How Cloud Data Centers Differ from Traditional Data Centers
Every organization requires a Data Center, irrespective of their size or industry. A Data Center is traditionally a physical facility which companies use to store their information as well as other applications which are integral to their functioning. And while a Data Center is thought to be one thing, in reality, it is often composed of technical equipment depending on what requires to be stored β it can range from routers and security devices to storage systems and application delivery controllers. To keep all the hardware and software updated and running, a Data Center also requires a significant amount of infrastructure. These facilities can include ventilation and cooling systems, uninterruptible power supplies, backup generators, and more.
A cloud Data Center is significantly different from a traditional Data Center; there is nothing similar between these two computing systems other than the fact that they both store data. A cloud Data Center is not physically located in a particular organizationβs office β itβs all online! When your data is stored onΒ cloud servers, it automatically gets fragmented and duplicated across various locations for secure storage. In case there are any failures, yourΒ cloud services providerΒ will make sure that there is a backup of your backup as well!
So how do these different modes of storage stack up against each other? Letβs compare them across four different metrics: Cost, Accessibility, Security and Scalability.
Cost
With a traditional Data Center, you will have to make various purchases, including the server hardware and the networking hardware. Not only is this a disadvantage in itself, you will also have to replace this hardware as it ages and gets outdated. Moreover, in addition to the cost of purchasing equipment, you will also need to hire staff to oversee its operations.
When you host your data on cloud servers, you are essentially using someone elseβs hardware and infrastructure, so it saves up a lot of financial resources which might have been used up while setting up a traditional Data Center. In addition, it takes care of various miscellaneous factors relating to maintenance, thus helping you optimize your resources better.
Accessibility
A traditional Data Center allows you flexibility in terms of the equipment you choose, so you know exactly what software and hardware you are using. This facilitates later customizations since there is nobody else in the equation and you can make changes as you require.
With cloud hosting, accessibility may become an issue. If at any point you donβt have an Internet connection, then your remote data will become inaccessible, which might be a problem for some. However, realistically speaking, such instances of no Internet connectivity may be very few and far between, so this aspect shouldnβt be too much of a problem. Moreover, you might have to contact your cloud services provider if thereβs a problem at the backend β but this too shouldnβt take very long to get resolved.
Security
Traditional Data Centers have to be protected the traditional way: you will have to hire security staff to ensure that your data is safe. An advantage here is that you will have total control over your data and equipment, which makes it safer to an extent. Only trusted people will be able to access your system.
Cloud hosting can, at least in theory, be more risky β because anyone with an internet connection can hack into your data. In reality, however, most cloud service providers leave no stone unturned to ensure the safety of your data. They employ experienced staff members to ascertain that all the required security measures are in place so that your data is always in safe hands.
Scalability
Building your own infrastructure from scratch takes a lot of input in both financial as well as human terms. Among other things, you will have to oversee your own maintenance as well as administration, and for this reason it takes a long time to get off the ground. Setting up a traditional Data Center is a costly affair. Further, If you wish to scale up your Data Center, you might need to shell out extra money, albeit unwillingly.
With cloud hosting, however, there are no upfront costs in terms of purchasing equipment, and this leads to savings which can later be used to scale up. Cloud service providers have many flexible plans to suit your requirements, and you can buy more storage as and when you are ready for it. You can also reduce the amount of storage you have, if thatβs your requirement.
Canβt decide which one to go for?
There is no universal right choice. Your choice should depend on what your business is prepared to take on, what your exact budget is, and whether or not you have an IT staff available to handle a physical Data Center.

What Are the Trending Research Areas in Cloud Computing Security?
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, butΒ cloud networking and cloud computing securityΒ has come a long way with better IAM and other data protection procedures.
Cloud networking and cloud computing securityΒ revolves around three things-
- Safeguarding user accounts in the cloud
- Protecting the data in the cloud
- And, then the third aspect is application security.
Trending Research Areas in Cloud Computing Security
Following are the trending research areas in theΒ Cloud Computing Security:
- Virtualization:Β 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.
- Encryption:Β 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.
- Denial of Service:Β 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.
- DDoS Attacks:Β 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.
- Cloud Security Dimensions:Β 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.
- Data Security:Β 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.
- Data Separation:Β 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.
Data Center Interconnect: Details, Challenges & Solution
The ever-increasing demand for the Data-Center and network virtualization has its ramifications on the Data Center interconnect (check outΒ Cloud Cover). It has gained the attention of the service providerβs 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, letβs 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 thatβs 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:
- East-West Traffic:Β The traffic between Data-Centers is referred as East-West.
- North-South:Β 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. Letβs take a look at some of them.
Distance:Β 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:Β 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. Itβll make sure that they may quickly scale to address the spikes in traffic.
Data Security:Β 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, whatβs more, crucial is the security of in-flight data.
Automated Operations:Β 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 shouldnβt take much time to establish a connection between Data-Centers and shouldnβt require on-going manual operations.
Rising Costs:Β 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 shouldnβt 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.

Comparing internet lease lines and broadband services
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 oneβs 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 isnβt dependent in contention with other users.
Broadband, on the other hand, is a non-dedicated connection between the local exchange and oneβs 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 oneβs 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, whileΒ leased linesΒ are dedicated circuits coming only to your premises β that means no sharing in leased lines
- Consistent speeds and contention: Since various premises share the same cable split βnβ 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, youβre 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 donβt 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 isnβt 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.
Network Security, the key to VoIP adoption
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 β reliability combined with steep cost savings and a plethora of productivity-enhancing features make it the communication network of choice for enterprises.
But, in todayβs 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 threatΒ β this usually involves eavesdropping and phreaking β 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 MalwareΒ β the bane of all Internet-based services β VoIP services are also open to attacks by malware, worms, and viruses.
- Denial of ServiceΒ β Another threat that is used most often against Internet-based services β DOS can bring the communication network to a halt by flooding it with unnecessary messages.
- Call tamperingΒ β 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 β
- SBCs (Session Border Controllers)Β β 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-virusΒ β 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.
- EncryptionΒ β 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 β from mobiles or from home devices.
- Call restrictions, authorization, and passwordsΒ β 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 InspectionΒ (DPI) β DPI monitors the network and can identify extra or fraudulent data packets and flag them for review.
- VoIP authenticationΒ protocolsΒ β the most stringent of these protocols is the so-called three-way handshake β 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 β the benefits of the technology ensures that β 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 β 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.
The 3 core components that make up Enterprise Collaboration Services
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 β the expectation of the employees, clients and end customers also rise β employees and clients demand to be connected 24Γ7 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 β 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 β
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 asΒ cloud computingΒ to offer exceptional communication and collaboration services to users, where they are β either within office or outside.
This includes a Wide Range of Services and Solutions with Capex and Pay-as-You-go modelsβ
- Basic Video conferencing
- Mobility solutions to connect people on the go
- High end bridging solutions
- Large display solutions for niche applications such as NOCs and digital signage.
- 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 β 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 β small, medium or large β 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 todayβs global workplace.

VoIP services β How does it work?
The world over, communication β reliable and secure β 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 β VoIP services market is predicted toΒ 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 uncompressedΒ 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 β endpoints include applications running on mobile devices or dedicated desktop VoIP phones. VoIP is also available as a computer to computer service wherein you donβt need any extra hardware β calls can be made directly from the computer with just a microphone or a soundcard β 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 β 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 β while cost savings may be one of the main reasons for migrating to VoIP (on an average, businesses can save betweenΒ 50 β 75 %Β 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.

5 Key VoIP features that Empower 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 βpay per useβ 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 businessβ 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.

Cloud Driving Transformation in the Healthcare Sector
The βSify: Power Discussionβ hosted at the βHealthcare Senate & Healthcare Information Technology Summit 2017β 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 βCheck-in / Checkout/ Post Checkout Careβ?
- Challenges in the Inter-departments users of IT systems at the hospitals. For example, the HIS at times hasnβt 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 β 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 βNetwork as a serviceβ 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 βPer Bill generated i.e. Outcome Based Modelβ.
With this model, the role of the CIO will focus not on βSwitch on β Switch off issuesβ 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.
Conclusion
On the whole, it was a good participative discussion where the various points of view from the Business side, IT side and the service provider angle were discussed. Obstacles as well as advantages for adopting an agile cloud based model were deliberated upon and a need for business outcome based model to help IT and business alike was unanimously agreed upon.
New technologies and solutions β such as mobile apps, cloud computing, the Internet of Things, and analytics β are available to make healthcare organizations more accessible, simpler, faster, and more cost effective.
