Cloud computing is one of the hottest trends. Most technological solutions are now on cloud and the ones remaining are vying to be on cloud. Due to its exceptional benefits, it has magnetized the IT leaders and entrepreneurs at all levels.

What is Cloud Computing?

Cloud Computing is when many computers are linked through a real-time communication network. It basically refers to a network of remote servers that are hosted in Data Center, which further can be accessed via internet from any browser. Hence, it becomes easy to store, manage, and process data as compared to a local server or personal computer.

What is Cloud Networking?

The access to the networking resources from a centralized third-party provider using Wide Area Network (WAN) is termed as Cloud Networking. It refers to a concept where the unified cloud resources are accessible for customers and clients. In this concept, not only the cloud resources but also the network can be shared. With Cloud Networking, several management functions ensure that there are lesser devices required to manage the network.

When data began to move to cloud, security became a major debate, but cloud networking and cloud computing security has come a long way with better IAM and other data protection procedures.

Cloud networking and cloud computing security revolves around three things-

1. Safeguarding user accounts in the cloud
2. Protecting the data in the cloud
3. And, then the third aspect is application security.

Trending Research Areas in Cloud Computing Security

Following are the trending research areas in the Cloud Computing Security:

1. Virtualization: Cloud computing itself is based on the concept of virtualization. In this process, virtual version of a server, network or storage is created, rather than the real one. Hardware virtualization refers to the virtual machines that can act like a computer with an operating system. Hardware virtualization is of two types: Full Virtualization and Para-Virtualization.
2. Encryption: It is the process of protecting data by sending it in some other form. Cloud computing uses advanced encryption algorithms in order to maintain the privacy of your data. Crypto-shedding is another measure in which the keys are deleted when there is no requirement of using the data. There are two types of encryption used in cloud computing security including Fully Homomorphic Encryption and Searchable Encryption.
3. Denial of Service: It is a type of attack in which an intruder can make the resources of the users unavailable by disrupting the services of the internet. The intruder makes sure that the system gets overloaded by sundry requests and also blocks the genuine incoming requests. Application layer attack and Distributed DoS attack are some of its types.
4. DDoS Attacks: It stands for Distribution Denial of Service. It is a type of Denial of Service attack in which hostile traffic comes from various devices. Hence, it becomes difficult to differentiate between the malicious traffic and the genuine one. Application layer DDoS attack is another type of DDoS attack in which the attacker targets the application layer of the OSI model.
5. Cloud Security Dimensions: Software called Cloud Access Security Brokers (CASB) in between the cloud applications and cloud users, monitors all the policies related to cloud security and also enforces the cloud security policies.
6. Data Security: The Encryption method is used in protecting and maintaining the privacy of the data because security in the cloud-based services has always been the focal point. Due to some vulnerabilities and loopholes, data might get exposed to the public cloud.
7. Data Separation: An important aspect of data separation is the geolocation. Organizations should make sure that the geolocation for data storage must be a trusted one. Geolocation and tenancy are the major factors in data separation.

Cloud is one of the topics with no limit at all. With its help, you can perform any kind of project in order to enhance the performance in speed and magnify the security algorithm so as to prevent the files from being hacked.

Sify allows enterprises to store and process data on a variety of Cloud options, making data-access mechanisms more efficient and reliable.

The ever-increasing demand for the Data-Center and network virtualization has its ramifications on the Data Center interconnect (check out Cloud Cover). It has gained the attention of the service provider’s network architecture making them think in the direction of load-sharing and distributed workloads. It has also become a way to connect various Data Centers in the cloud using SDN to allocate resources as per the requirement, automatically.

There was a time when Data Center interconnect (DCI) used to be simple. But due to the many technological advances and the availability of various options, there is a lot of confusion in the market. First, let’s take a look at the Data Center interconnect market:

Intra-Connections-The intra Data Center interconnect refers to all the connections within the Data Center. They can be within one building, or between Data-Center buildings within the campus. The connections may be at a distance of meters to few kilometers.

Inter-Connections-These refer to the connections that are between the 10km-80km range. Undoubtedly, the connections may be far apart, but inter-Data Center connectivity market is focused within this range.

There are Data Centers situated to serve the entire continent and there are others focused in a specific metro area.

Case-Study (Online Retailer)

You are a global retailer, and you might have several thousand transactions running in a second. When the Data Center is far away, the data is more secure from the various natural disasters. But, then there is a challenge that comes with greater distance. The transactions that are in-flight may get lost due to latency.

So for online transactions, there is a local Data Center (primary Data-Center), and the other is a secondary Data Center that’s almost 80Km away. The benefits, in this case, are dual. First, your transactions will not be affected by the distance and the data is secure. Second, none of the transactions are lost due to latency. So in the worst case, only a small number of transactions might get affected or lost.

The traffic may be within Data-Centers, or between two Data-Centers for the load-balancing. Now the two important traffic categorization:

1. East-West Traffic: The traffic between Data-Centers is referred as East-West.
2. North-South: The traffic to the user is referred to North-South.

Which DCI Challenges Have To Be Overcome?

There are many challenges that have to be overcome. Let’s take a look at some of them.

Distance: The DCI applications vary greatly in size and scope in response to the Data Centers that may be dispersed across the globe or metro area or around a country. So it becomes critical to carry most of the bits farthest, but when the distance increases the latency increases as well. While choosing shortest route may minimize latency, bad equipment may also lead to latency.

Connection Capacity: The Data Centers store and deliver applications. The data sets that are coming in a Data-Center or leaving it may be very large. The range may vary from few hundred Gigabits to Terabits. To handle such large data, the equipment should offer reliable and high-capacity connections. It’ll make sure that they may quickly scale to address the spikes in traffic.

Data Security: Data Centers store a large amount of critical information. It demands that the Data Center connections are reliable, safe, and encrypted to avoid costly breaches and also data losses. While the security of stored data is crucial, what’s more, crucial is the security of in-flight data.

Automated Operations: As we know, manual operations may be labor-intensive, complicated, slow and may be error-prone as well. So it is very much imperative that complexity and lower speed of connection that arises out of manual operations may be minimized by moving towards automation. It shouldn’t take much time to establish a connection between Data-Centers and shouldn’t require on-going manual operations.

Rising Costs: When a large stream of data enters and leaves the Data-Center, it should be carried out in the most cost-efficient manner. If the Data Centers remain viable, the costs shouldn’t rise in the same way as the bandwidth. To take care of these issues, the solutions in high-speed networking should offer a solution that connects Data Centers at the lowest cost per bit.

Are you in search of the best application hosting? Well, choosing the best-dedicated server for your enterprise could be a task in itself. But why dedicated web server? A dedicated web server ensures resilience and resources to host a web application.

Selecting a dedicated server which is fast, secure, properly managed, and has the perfect software tools is very much essential for the growth of your business. A company looking forward to having more control and power will opt for a service provider who offers dedicated server hosting. The server is built and maintained by the provider, thus cutting down the cost of purchasing your own server.

So, let us take a sneak peek into the advantages of choosing a dedicated server hosting provider and some other useful tips in getting started with your new dedicated server.

Advantages:

1. High Performance and SecurityHow can you maximize the uptime for your website or application? It is through a dedicated hosting provider. Dedicated servers provide more reliability and stability than the shared hosting. It makes sure that you are not sharing your space with any other malicious software or a potential spammer. Dedicated server leads to enhanced security, this is the reason it is essential for companies taking transactions over FTP or SSL. Moreover, the best-dedicated server hosting comes with 24×7 support to deal with failures and complaints which further ensures high uptimes.
2. FlexibilityA dedicated server comes up with flexibility, as you can always customize your server as per client’s requirements of RAM, disk space, CPU, and software. If you want a customizable server environment, then a dedicated server might fit your needs.
3. Server Resources are not sharedChoosing a dedicated server fetches you all the resources of a server. With a dedicated server, your server won’t slow down, as there are no other applications sharing your space and clogging up the server’s RAM and CPU. In case of dedicated hosting, your server bandwidth is only yours.
4. No Purchase and MaintenanceIf a company requires a dedicated hosting, and it does not have the time and resources to manage a server, the dedicated hosting is a low-cost way to access the resources of the server. Dedicated server hosting helps in maintaining the server equipment, thus reducing the overhead for a business.
5. Full ControlOne of the most widely held benefits of dedicated hosting is that you have full control on your server. You decide which site management tool and application you wish to deploy, provided your hosting provider can service them.

Factors to Consider while Purchasing Best Dedicated Server Hosting Plan

Developers and business owners try to find the best-dedicated server hosting because they can be configured easily in order to quench the programming requirements, server load support, and top-notch security. So, here are the points which should be kept in mind before purchasing a dedicated server hosting plan:

1. Different types of RAM- Primarily used is DDR3, DDR4, and ECC options in present
2. Focus on CPU Benchmark Performance- Know the difference between Xeon, Atom, and Opteron product lines
3. Choice of Bandwidth and Data Center Concerns- Internet Backbone Network Speeds, Power Supply, and Cooling
4. OS- Windows and LINUX; and choosing between different LINUX distributions
5. Technical Support- the capability to support your clients
6. Disk Drive Storage- HDD vs Solid State Drives (SSDs)

Almost all the users of dedicated servers yearn for the best hardware configurations at the lowest possible price. However, some choose to bargain on the older equipment available at a particular discount. Legions of mobile applications that come with custom code require complex web server that shared hosting plans do not support. However, it is advised that the business owner should consult with their system administrator to discover the development requirements for their productive applications. Novice development in cloud hosting may soon have an upper hand over the dedicated server plans, and cheaper cum better plans are available on VPS plans with more resource allocation. Hence it becomes quintessential, as how to keep your online business up to date in a rapidly innovating web hosting industry.

Focus on your core business and outsource the complexities of Data Center management with Sify

The internet can be accessed in many ways, as evidence in the form of the evolution of the internet connections over the last few years. Today, the broadband is usually considered as the most popular medium for accessing the internet, especially in homes. However, when it comes to larger establishments and commercial spaces such as hospitals, corporate offices, and colleges, internet leased lines are preferred. Why is that, exactly?

Defining internet leased lines and broadband connections

An internet leased line is a premium, dedicated internet connection between the local exchange and one’s premises. Usually delivered over fibre, an internet leased line, which is also otherwise called as a private line, data circuit, a dedicated line or an ethernet leased line, provides symmetrical, uncontended, and identical internet upload and download speeds. An internet leased line has a fixed bandwidth and isn’t dependent in contention with other users.

Broadband, on the other hand, is a non-dedicated connection between the local exchange and one’s premises. Not only does it have a variable bandwidth, but it also provides asymmetric speeds which are slower for uploads and faster for downloads as well as is subject to contention with other users.

Difference between internet leased lines and broadband

• Connection: Internet leased lines and broadband connect to the business premises in different ways. While they both are transferred via cables, the difference lies in how. An individual gets their internet from the local cabinet/box on the street/apartment building where one lives. That box contains a copper-wire or fibre connection to one’s premises and delivers the internet. Thus, the exchange is via a series of cables in both cases. However, in broadband connections, cables are split between all other local premises, while leased lines are dedicated circuits coming only to your premises – that means no sharing in leased lines
• Consistent speeds and contention: Since various premises share the same cable split ‘n’ number of ways in broadband, the speed is also affected. So, even if one gets a 76Mbps connection, the speed varies according to how many other people are using the broadband at the same time. Realistically, at peak time, one might be getting a much slower speed if everyone is using unlimited downloads. However, with an internet leased line, there is no slower speed because there is no contention with others. Even if you have only a 10Mbps connection, you’re getting the 10Mbps in its entirety.
• Reliability and SLAs: When it comes to issues such as the internet being down, for how long can you work without it? This is where Service Level Agreements come in. Some broadband providers don’t even provide SLAs, but do mention about the internet being fixed as quickly as they can in their service terms. However, one might have to wait for a few days. With internet leased lines, users can expect strong, to-the-point SLAs with better reliability. In fact, leased line issues might even get fixed within a matter of a few hours, while of course, keeping the issue in mind.
• Bandwidth choices: When it comes to internet leased lines, users can take their pick from a wide range of bandwidth choices, right from 64 Kbps and 128 Kbps to 2 Mbps, 80 Mbps, and even as high as 155Mbps. The choices are much more restricted and lesser when it comes to broadband.

So, while broadband might be cheaper than an internet leased line, but it certainly isn’t a match for the latter when it comes to the above-mentioned aspects. When one is considering a new internet solution, the best thing would be to analyse what you exactly need and compare the options for both broadband and internet leased lines before zeroing in on one.

There are numerous internet leased line providers in India and Sify is proud to be one of the oldest & widest network coverage providers.

With growing Internet infrastructure and new technologies, VoIP (Voice over Internet Protocol) has gained tremendous popularity among businesses. Regardless of size and industry, organizations are migrating their communication network from traditional PSTNs to VoIP. The wide-ranging benefits of the system are bound to attract businesses from across the board – reliability combined with steep cost savings and a plethora of productivity-enhancing features make it the communication network of choice for enterprises.

But, in today’s landscape of increasing cyber-attacks, VoIP must also strengthen its security protocols to ensure businesses are not left vulnerable to malicious cyber agents.

Main Security Threats faced by VoIP

VoIP networks are open to the following threats

• Identity and service threat – this usually involves eavesdropping and phreaking – Eavesdropping is a scenario in which attackers infiltrate the VoIP lines to listen in to conversations to gain access to sensitive business data or private information and accounts to carry out corporate sabotage or identity theft. Phreaking is a term used for the practice of passing off call charges to other accounts by getting unauthorized access to their VoIP service.
• Viruses and Malware – the bane of all Internet-based services – VoIP services are also open to attacks by malware, worms, and viruses.
• Denial of Service – Another threat that is used most often against Internet-based services – DOS can bring the communication network to a halt by flooding it with unnecessary messages.
• Call tampering – call tampering refers to the practice of interrupting the call by injecting noise packets in the network or withholding call packets to cause call delays and poor call quality. Call hijacking is another form of call tampering in which an outside party enters the call and tricks the person on the other line by masquerading as the original caller.

How are VoIP service providers countering these security challenges?

Service Providers understand that the continued popularity of VoIP services depends, to a large degree, on how secure and comfortable businesses feel while using these services. The VoIP providers and organizations have given top priority to securing their communication networks and have spent the considerable amount of effort and money in putting together some of the most cutting-edge security solutions to safeguard their systems.

The threats listed above can be taken care of by a judicious mix of preventive measures –

• SBCs (Session Border Controllers) – SBCs manage VoIP protocol signals and with in-built security firewalls they are the first and one of the most effective lines of defense against cyber threats.
• Anti-virus – installing and operating an updated anti-virus or anti-malware on all connected computer hardware is especially important as they can enter the VoIP network through unsecured channels.
• Encryption – usually provided by the service providers as an add-on service to secure the network and is highly recommended for enterprise users. VoIP encryption is especially important when the organization has many users connecting from outside the office network – from mobiles or from home devices.
• Call restrictions, authorization, and passwords – businesses must restrict access to the VoIP network by making sure that only the required people are given access to the network. This along with call restrictions, to track and monitor call activity and stringent password policies can ensure that people within the organizations are made aware of the importance of keeping the network secure.
• Deep Packet Inspection (DPI) – DPI monitors the network and can identify extra or fraudulent data packets and flag them for review.
• VoIP authentication protocols – the most stringent of these protocols is the so-called three-way handshake – Challenge-Handshake Authentication Protocol (CHAP) uses a three-step process to test the legitimacy of the incoming messages and is far superior to basic password protection which is widely used.

Conclusion

While the future of VoIP services is secure – the benefits of the technology ensures that – security concerns that have dogged all Internet-based services are also giving network engineers sleepless nights. From cloud platforms to on-premise IT infrastructures, all systems have vulnerabilities that can be exploited and as Cyber-attacks become more aggressive and better organized no one is truly safe.

It is estimated that the global cost of cybercrime will reach $2 trillion by 2019 – keeping these numbers in mind organizations can no longer count on just plain old luck to keep their businesses safe, they need to be prepared for the worst. And this is especially true for mission-critical functions like communication!

Here, VOIP is clearly the solution of choice for organizations looking for a secure communications network.

A lot is being written these days about the increasingly important role of communication and collaboration services in running a business smoothly. As the world becomes more connected and doing business across vast geographies becomes the norm – the expectation of the employees, clients and end customers also rise – employees and clients demand to be connected 24×7 from anywhere in the world and customers expect near instantaneous resolution of their problems.

In this scenario, most organizations need to revaluate their collaboration systems. Several ICT players have harnessed technology to provide solutions that allow real time collaboration across devices – making it easier for people to work together without wasting time and money in traveling across distances.

Many of you might wonder what services are available under the umbrella of collaboration services and this is just what we will address below.

Components of Collaboration solutions

A comprehensive end-to-end Collaboration solution has three main components –

Audio Visual Collaboration Solutions

A few years ago, AV collaboration meant basic video conferencing solutions from fixed meeting or boardrooms, but service providers are now leveraging latest digital technologies such as cloud computing to offer exceptional communication and collaboration services to users, where they are – either within office or outside.

This includes a Wide Range of Services and Solutions with Capex and Pay-as-You-go models–

1. Basic Video conferencing
2. Mobility solutions to connect people on the go
3. High end bridging solutions
4. Large display solutions for niche applications such as NOCs and digital signage.
5. AV integration solutions for creating immersive communication environments for large areas such as board rooms, VC rooms, auditoriums etc.

Collaboration services also offer additional functionalities and benefits – recording and streaming facilities, integration with business applications, flexible and user-friendly interface etc. And businesses have added flexibility in terms of using these services either as an on-premise, hosted or hybrid model.

Hosted Contact center solutions

The second element of collaboration services is tailored to the needs of businesses – small, medium or large – whose business models revolve around customer interactions which necessitates the need to run customer care centers.

Customer experience during their interactions with provider organizations are key business drivers and hence critical to businesses. To enable enhanced customer experience, Contact center solutions have evolved over years with the help of state-of-the-art technology. These technologies are normally Capex intensive. However, today businesses can opt for Contact center-as-a-service model which has no upfront CAPEX costs and is completely flexible and scalable. This as-a-service model allows businesses to outsource all the technological aspects of contact centers and concentrate on their core business operations.

VoIP security and TDM to IP conversion with SBCs

VoIP services have taken on a mission critical role in many organizations, hence it is imperative to protect and isolate the VoIP infrastructure from external threats and allow seamless communication between multiple voice devices.

VoIP security forms an important component of Collaboration services. With SBCs (Session Border controllers) organizations can centrally manage VoIP policies and bandwidth for VoIP devices and applications and protect the network from cyber-attacks.

One of the hallmarks of a successful enterprise is how well its employees work together as a team. Teamwork and Collaboration is essential for running a successful organization, more so in today’s global workplace. Professional collaboration solutions based on the latest technology delivers on several fronts – cost, productivity and flexibility – and for many organizations is one of the smartest business moves for staying competitive in the current global marketplace.

 

When it comes to providing collaboration and communication services to organizations spread over continents, Sify which is a pioneer in Voice and Data services, with its decades of experience in data communication solutions, network integration services, Data Center services and application integration services can provide enterprise grade collaboration services to verticals ranging from Healthcare, IT/ITes, Manufacturing, Retail, Education and more.

 

The world over, communication – reliable and secure – is taking on a more critical role in the functioning of organizations and businesses. The more geographically spread your organization is, the more important it becomes to keep communication networks up and running.

Voice Over Internet Protocol (VoIP) has gained tremendous traction over the last decade and has become a popular choice for organizations looking for cost-effective and reliable communication networks to manage their growing business – VoIP services market is predicted to expand 10 % every year until 2021 and touch $140 billion.

What is VoIP (Voice over Internet Protocol)?

VoIP services use Internet connections to make phone calls. The analog voice signal is turned into data packets and transmitted over the Internet, enterprise local networks or Wide area networks. Apart from voice data, VoIP also transmits multimedia content over IP networks.

How does VoIP work?

VoIP has become an increasingly popular choice for business communications and provides a stable alternative for traditional telephone networks known as Public Switched Telephone Networks(PSTN).

VoIP provides a reliable and secure communication channel with highly cost-effective models. To understand how VoIP can achieve this, one needs to look at the technology behind the services.

VoIP uses a codec to encapsulate audio into data packets and transmits them across an IP network and decapsulates them back into audio at the other end of the connection. VoIP uses standard codecs by the International Telecommunication Union, such as G.711 for transmitting uncompressed packets, or G.729 for compressed packets. This compression is typically used to decrease bandwidth requirements.

After it is encapsulated onto IP, voice data is transmitted via the real-time transport protocol or through its encrypted variant, secure real-time transport protocol. The most common communication protocol is Session Initiation Protocol (SIP) and is used for signaling that is necessary to create, maintain and end calls.

In an enterprise setup, VoIP emulates the traditional telephone networks with dedicated instruments – endpoints include applications running on mobile devices or dedicated desktop VoIP phones. VoIP is also available as a computer to computer service wherein you don’t need any extra hardware – calls can be made directly from the computer with just a microphone or a soundcard – the most popular example of this is Skype!

In many organizations, there may be an existing PBX system and VoIP system can use a SIP codec to connect with the PBX and allow it to manage user phone numbers; gateways to connect networks and provide failover in the event of a network outage.

VoIP networks have several other components such as session border controllers to provide security, call-policy management and inter-operator network connections. VoIP also has a host of additional functionalities which help users and management to operate smoothly – these are location-tracking databases for call routing and management platforms to collect call-performance statistics for voice-quality management.

Conclusion

A peek into the VoIP technology lays bare the reason for its popularity, especially among businesses – while cost savings may be one of the main reasons for migrating to VoIP (on an average, businesses can save between 50 – 75 % after switching to VoIP), businesses have consistently seen enormous jumps in productivity thanks to additional functionalities such as unified communication and telecommuting. In the current market scenario, where customers expect quick responses and a seamless customer experience is key to business success, VoIP has quickly become the only communication choice for most organizations.

Our cutting-edge networking services ensure reliable data connectivity services as well as the best-in-class Voice services in India – all available as cost-effective payment models aligned to scale with the growing needs of individual businesses.

During the early days of the VoIP (Voice over IP) technology, it was surrounded by skepticism over its long-term viability and its suitability across industries. However, the past decade has seen VoIP being firmly recognized and implemented across businesses of every size and industries of every nature.

VoIP in its current evolved form offers many such features that help provide increased functionality, cost-effectiveness, and improved efficiency. Beyond the basic options such as voicemail, call waiting and call forwarding, there are many strategic features that empower businesses.

Security

Security for its communications is fundamental for all businesses. VoIP offers that by adding a layer of security for all voice communications and encryption for media and other data. Most Voice over IP providers use Multiprotocol Label Switching (MPLS) at both ends, ensuring greater security for the users.

Mobility

VoIP solutions enable remote operation, giving the employees and managers, spread across vast geographies, access to constant and reliable communication, even when they are away from their offices. It reduces the requirement to travel, allows them to telecommute and increases team productivity. It also presents a wide reach across borders for the businesses at a nominal cost.

Scalability

As against a traditional alternative, where scaling up translated into expensive hardware and access to basic features entailed a minimum set-up size, VoIP uses the limited resources of money, space and manpower more efficiently. There is a reduced requirement for infrastructure freeing up physical space. There is a built-in flexibility of ‘pay per use’ that allows a business to scale up or down without the prohibitive expense of redundant infrastructure/ related software or the associated time to implement and operate the revised solutions.

Unified Communications

Unified communications (UC) fuses and brings together all corporate communication channels such as voice, chat, video, mobile and email as a part of a single integrated suite. UC, when linked with the right business processes, can dramatically amplify productivity. This is especially significant in industries with a sizeable and continuous customer interface as it provides customers with greater flexibility while communicating with the company.  UC makes it possible for businesses to maintain a single easy-to-manage network instead of wrestling with different infrastructures for voice, data, and video.

Analytics

VoIP provides the businesses with an option for analysis of their interactions with their employees and the customers. The nature of the industry that these businesses operate in, determines the level of analytics that they need. However, the information is made available for all interactions with the VoIP solution. The analysis could be used to benchmark call efficiency KPIs, reduce turnaround time for troubleshooting, track call quality, agent or team specific metrics or even for compliance purposes. VoIP systems offer call recording and built-in reporting tools to support a business’ unique objectives.

These features and functionality offered by a VoIP (Voice over IP) solution can positively impact team productivity, customer relations, and core business operations. VoIP solutions can achieve this by enabling employees to work efficiently while juggling multiple devices, working from remote locations or constantly traveling for work.

Additionally, the constantly evolving nature of technology ensures that innovative new features are incorporated in the VoIP solution on a regular basis. As VoIP solutions ably support the new environment and scale quickly as the business grows or shrinks, it would have a significant influence on businesses over the next couple of decades.

The “Sify: Power Discussion” hosted at the “Healthcare Senate & Healthcare Information Technology Summit 2017” organised by the Indian Express Group and Sify Technologies discussed the various benefits that cloud can bring to the Indian healthcare sector.

The CXOs who participated in the power discussion hosted by Sify shared their challenges in the ICT space and subsequently, various views were shared by the panellists and Sify on how the cloud technology can solve their pain points and finally help in building better patient experience.

Summary of Challenges

• Increasing Data volumes is becoming unmanageable in preserving, optimising and retrieval of data. The Cost associated with that is also an issue.
• Can IT play a role in reducing the time of the patient in “Check-in / Checkout/ Post Checkout Care”?
• Challenges in the Inter-departments users of IT systems at the hospitals. For example, the HIS at times hasn’t been successful in reducing the pain points of the doctors with Care Teams.
• Disparate IT systems do not talk to each other and are not compatible, so there should be a common platform that allows different technologies to work seamlessly.
• Hospitals should prioritise in terms of what they want to achieve and accordingly how IT can play a role. At times, the perception is that IT has a magic wand, and any problem in hospital, IT is made a scapegoat.

The Case for Cloud Computing

Anindya Sen, Transformation – Evangelist, Sify Technologies, spoke extensively on how cloud can solve various challenges faced not only by the IT function but also the functions in the hospitals. He started with a specific example of the cloud implementation for the radiology department at Cancer Treatment Services International (CTSI). In each of the twelve CTSI hospitals, which were hitherto running on separate IT systems, were now completely moved on cloud. The data was now directly fed to the radiology departments of these twelve hospitals. It helped radiologists to serve the patients by doing targeted radiation.

One of the panellists asked about how cloud can reduce cost for the organisations. Cloud can significantly slash costs for companies who want to serve multiple locations using the cloud technology, however, the cost advantage might not fructify if it were a single location. Nevertheless, the benefits of cloud beyond cost parameters only were discussed for such scenarios.

A specific discussion happened in terms of healthcare industry where in spite of adopting Cloud, the IT team still has a task at hand in managing end points, their networking, etc. Network-as-a-service, a relevant example in this case was discussed to take the pain away from internal network management. Sify has provided “Network as a service” to many companies having a wide geographical presence using the cloud model.

The panellists were of the consensus that different components of IT like networks, applications, different patient systems etc. on cloud hosted by a single CSP, who partners with different domain experts and partners can unleash the potential that cloud can offer.

Sify explained a case study of Uttar Pradesh Power Corporation Ltd (UPPCL). Sify has hosted the IT infrastructure, end-to-end on cloud, partnering with the right domain experts and service providers for the various components of the IT infrastructure be it network, security, antivirus etc. The customer pays Sify on “Per Bill generated i.e. Outcome Based Model”.

With this model, the role of the CIO will focus not on “Switch on – Switch off issues” but concentrate on the Innovation, Patient Experience, Improve Inter-Departmental Coordination, Post Checkout Patient Care, etc. Various other models like per bed, per patient were also deliberated.

There is also a lot of potential waiting to be tapped in the on-premise cloud space. On premise cloud fits well with organizations having large IT resources in-house. IT and FMCG companies are a nice fit. Sify provides their infrastructure and services to these companies. This model was suggested by panel members specifically for concentrated IT landscapes.

With global issues like Global warming, floods are becoming more frequent and thus the availability of systems can get affected. One of the panellists spoke about how during the Chennai floods, because the systems were hosted in one place in Chennai, the hospitals in other cities were affected however in one of the similar instances of floods, this was avoided because now the systems were working on cloud. This brings in the case for DR as a service. Cloud can also be helpful in bringing innovation in IT processes.

The Potential of Telemedicine

Telemedicine has not been able to take off in India and the reasons to which were discussed. Various suggestions on how telemedicine can be made more reasonable for the medical community and patients alike.

One of the reasons, as a panellist claimed, that was not allowing telemedicine to take off is there is no certainty on who will bear the cost. It works for the government, who pays for it entirely however for private hospitals, there is no business model.

Notwithstanding, telemedicine can be useful for patient scheduling, touchpoints, delivering care and administration process. There was also a broad consensus that telemedicine can be tremendously beneficial for secondary care i.e. once the patient has visited the doctor personally and his case is well understood by the doctor, the patient need not visit him the next time.

The treatment can happen using telemedicine unless it is necessary for an in-person visit. So the school of thought in the healthcare industry about the necessity to give the touch and feel for the patient is reducing and is a myth. With IoT technologies, the medical devices are also getting connected and this can be a contributing factor for the emergence of telemedicine in India.

As more and more businesses, both big and small, are jumping on the VoIP (Voice over IP) bandwagon, it is interesting to examine what is causing this exodus from the traditional alternative of PSTN (Public Switched Telephone Network) including Mobiles and Landlines.

In order to understand the reasons for the switch, it is important to first appreciate what is significant for these businesses while opting for a communication system. The chief concerns for businesses, irrespective of their size, while choosing a network are,

• How to reduce costs and at the same time not compromise on the quality of the communication system.
• Is there a way that would improve communication with customers and employees and better connect them?
• How to achieve more value for your money and get additional features at the same cost.
• Can the communication system contribute to an increase in efficiency and productivity?

As VoIP addresses these concerns and provides a powerful tool for businesses to ‘up their game’, enterprises in increasing numbers are opting for this alternative.

Cost-Effective Choice

A VoIP solution has a definite edge over its PSTN alternative as it offers free CUG (VoIP-to-VoIP) calling for both local and international. The calls made to mobile and landline phones through VoIP have nominal subscription fees as against a much more expensive PSTN alternative. The sound quality is continually improving as the technology is evolving, providing superior communications and better filtering of background noise with VoIP. Its online conferencing and other features help reduce the requirement for travel. It also has a lesser bandwidth requirement (10 Kbps) than the PSTNs (64 Kbps).

Improve Communication with Customers and Employees

VoIP provides unified communication, helping the employees to work remotely from any place with an Internet connection and ‘take the office’ with them. It also provides the ‘presence’ technology that enables users to see if employees are available and accordingly get in touch with them. PSTNs on the other hand, are able to provide the remote extension facility only with dedicated lines for each extension and hence are very expensive.

More Value for Money

VoIP solution provides an ease of scalability without adding significant infrastructure and cost to the decision. Additionally, VoIP offers call waiting, call forwarding and call transfer options as a standard offering, but the same is available in PSTNs at an additional cost.

Increased Efficiency and Productivity

VoIP has an edge over its traditional counterpart as it allows businesses to get enterprise class software at an affordable cost. As the cost of scalability is low, even smaller businesses can enjoy customized solutions with many features as standard or as an affordable add-on. These lead to increased productivity, less down time, and hence more profit. However, as the service terminates when the Internet connectivity (power) is lost, organizations must have a VoIP backup plan. PSTNs, nevertheless, are able to continue service during power outages, as phone jacks do not require electricity.

Hence, traditional choices such as PSTNs are making way for VoIP as the latter are proving themselves as a powerful tool, giving the businesses a competitive edge and providing the ‘right-size’ technology at an affordable price.
