According to Gartner, most of midsize and enterprise customers will be adopting a hybrid or a multi-cloud strategy. Companies have already realized that in order to move to public cloud, it is important to structure workload in hybrid cloud model.

Companies must understand that hybrid IT is not an easy methodology and therefore they must organize their existing IT resources and application workloads both on-premises and in public cloud efficiently to accomplish the goals of hybrid model. Additionally, they must also look for right skills for different private/public clouds and different sets of tools from respective cloud providers.

At Sify, we define some guidelines and structure to right fit your workloads in Hybrid Cloud. Please read on to know how Sify can help customers identify the right cloud (from the set of appropriate private and/or private clouds) for different sets of workloads.

Unique Challenges in Hybrid Cloud

In hybrid cloud, there are some unique challenges that businesses need to address first. key challenges that need to be addressed while designing solution on Hybrid Cloud are mentioned herein.

• Generally, it is very difficult to identify the most suitable cloud environment and manage the cost of different clouds.
• Though all cloud environments are powerful in providing features like scalability and elasticity, however the process of managing a hybrid cloud is quite a complex task.
• Security Risks: The threat of data breach or data loss is perhaps the biggest challenge faced during hybrid cloud adoption. Generally, companies prefer on-premises private cloud to protect data locally. However, in order to ensure top-tier security of data and applications on hybrid cloud, companies must draft robust data protection policies and procedures.

Identify Applications for Hybrid Cloud

It is very important to identify applications for hybrid cloud, and your decision must be based on application’s architecture, behavior and user accessibility. Below are some key points to remember while designing Hybrid Cloud strategy: –

• Consider the compatibility of applications before deciding whether you want to continue running the applications in an on-prem cloud environment or migrate them to Public Cloud.
• Identify the running cost/budget for an application and compare it with different cloud providers to choose the most suitable cloud platform that suits your budgetary outlines and business requirements.
• Pay due attention to licensing requirements before migrating to Public/Private Cloud because a minor loophole in this aspect can have a major impact on the overall business.
• Re-look experience of existing IT team to manage different Private/Public cloud seamlessly.

Why VMC on AWS as Hybrid Cloud Choice?

VMware Cloud (also called as VMC) on AWS brings VMware’s enterprise-class Software-Defined Data Centre software to the AWS Cloud and enables customers to run production applications across VMware vSphere-based private, public, and hybrid cloud environments, with optimized access to AWS services.

AWS is VMware’s preferred public cloud partner for all vSphere-based workloads. The VMware and AWS partnership delivers a faster, easier, and cost-effective path to the hybrid cloud while allowing customers to modernize applications enabling faster time-to-market and increased innovation.

New Amazon EC2 i3en.metal instances for VMware Cloud on AWS, powered by Intel Xeon Scalable processors, deliver high networking throughput and lower latency so you can migrate data centres to the cloud for rapid data centre evacuation, disaster recovery, and application modernization.

VMC on AWS can be the right choice because VMware is trusted as a trusted virtualization platform for many years in the industry and enterprise VMware ensures that all your applications run seamlessly. Plenty of companies are already running on VMware platform and have applications running on it. Below are some key identifiers for VMC on AWS:

• VMware SDDC is running on bare metal, which is delivered, operated, supported by VMware
• On-demand scalability and flexible consumption
• Full operational consistency with on-premises SDDC
• Seamless workload portability and hybrid operations
• Global AWS footprint, reach, and availability
• Native AWS services accessibility

How VMC on AWS Solution Works?

VMware Cloud on AWS infrastructure runs on dedicated, single tenant hosts provided by AWS in a single account. Each host is equivalent to an Amazon EC2 I3.metal instance (2 sockets with 18 cores per socket, 512 GiB RAM, and 15.2 TB Raw SSD storage). Each host is capable of running many VMware Virtual Machines (tens to hundreds depending on their compute, memory and storage requirements). Clusters can range from a minimum 3 hosts up to a maximum of 16 hosts per cluster. A single VMware vCenter server is deployed per SDDC environment.

How do We Access AWS Services?

For companies that are using VMware Cloud on AWS (VMC) as production environment for their business-critical application, it will require connectivity to an AWS account. This is enabled by an AWS elastic network interface which provides a 25Gbps connectivity between VMC and AWS. Applications deployed on VMC can leverage native AWS services for storage, EC2 instances, RDS Databases, load balancing and DNS routing, etc., providing customers with the best of both worlds. These native services can be accessed from applications deployed on VMC and include:

• Simple Storage Service (S3)

With the increased demand in scalability and flexibility of the infrastructure for organization to ramp up and speed up the go-to-market approach, it has become necessary to adopt the Public Cloud which can tackle this challenge efficiently. Therefore, businesses are looking for simple, reliable, and rapid migration of on-premises workload to Public Cloud with minimal disruption. Sify, being an AWS Advance Partner, has successfully carried out many large cloud migrations for several customers using CloudEndure and the best practices it brings in.

CloudEndure is a SaaS service offering from AWS to migrate workload from any source (physical, virtual, or private/public cloud) to AWS, from one AWS region to other AWS account (within same Account), and across different AWS accounts. It uses block level continuous replication to replicate data on to the target AWS environment.

To replicate data from source machine to target machine, we need to install agent on the source machine and should have the required CloudEndure license for migration. The migration license has expiry date post which the data replication stops.

The Continuous Data Replication task is performed and pushed to the staging area (includes Replication Server, EBS Volume, S3 Storage, Subnets and IP). The CloudEndure Service Manager ensures the co-ordination among the Source Machine, Replication Server and the Target Server.

Three points of contact for CloudEndure’ s components with the external network:

• The CloudEndure Agent needs to communicate with the CloudEndure Service Manager.
• The CloudEndure Agent needs to communicate with the CloudEndure Replication Servers.
• CloudEndure Replication Servers need to communicate with the CloudEndure Service Manager and S3.

CloudEndure helps you overcome below migration challenges effectively:

• Diverse infrastructure and OS type
• Legacy application
• Complex database
• Busy continuously changing workloads
• Machine compatibility issues
• Expensive cloud skills required
• Downtime and performance disruptions
• Tight project timelines and limited budget

Best Migration Practices that CloudEndure recommends:

Planning

• Begin by mapping out a migration strategy that identifies clear business motives and use cases for moving to the cloud.
• Migrate in phases/waves or conduct a pilot light migration in which you start with the least business-critical workloads.
• Do not perform any reboots on the source machines prior to a cutover.
• When scheduling your cutover, ensure that you allow enough time for data replication to complete and for all necessary testing to be carried out.

Licensing

• Ensure that you have sufficient migration licenses for your project.
• CloudEndure Migration license is free for 90 days of use following agent installation on source machine.
• While the use of CloudEndure Migration is free, you will incur charges for any AWS infrastructure that is provisioned during migration and after cutover, such as compute (EC2) and storage (EBS) resources.

Testing

• Check and optimize the network needed for migration.
• Perform a test at least one week before you plan to migrate your source This time frame is intended for identifying potential problems and solving them, before the actual cutover takes place.
• Train the staff early on CloudEndure and mitigate any risk during testing phase only.
• Ensure connectivity to your target machines (using SSH for Linux or RDP for Windows) and perform acceptance tests for your application.

Successful Implementation

• Cutover the machine on planned date.
• Carry out the acceptance test for the application migrated and functionality.
• Remove Source machines from the console after the cutover has been completed in order to clean up the staging area, reduce costs, and remove no longer needed replication resource.

Use cases

The Most Common uses cases for CloudEndure Migration are:

• Lift and Shift, then optimize
• Vast majority of Windows/Linux server when agent can be installed on source machine
• Replicating Block Storage devices like SAN, iSCSI, Physical, EBS, VMDK, VHD
• Replicating full machine/volume

Conclusion

You must keep these above points in mind while migrating to AWS using CloudEndure to reap the desirable outcomes. Sify would be glad to help your organization as your AWS Managed Services Partner for a tailor-made solution involving seamless, cloud migration experience and for your Cloud Infrastructure management thereafter.

In today’s hyper-connected and fast-paced global marketplace, connectivity is the lifeblood needed to keep businesses running smoothly. Enterprise, small or large, need reliable and fast communication networks to work and grow.

MPLS with its ‘labeling protocol’ provides organizations with a communication network that is completely dependable, fast, flexible and cost effective. The obvious and many benefits of MPLS Connectivity is driving businesses to consider switching to MPLS networks, but with the industry inundated by a wide range of services and management models the process of selecting an MPLS service provider can be long and complicated.

How do you evaluate the various telecom service providers and their offerings to get the best possible solution for your requirements? We list out the 5 key criteria that you need to consider.

Network coverage and reach of the MPLS service provider

The first thing that business need to check, is the network coverage offered by the service provider. Do all your desired locations fall under the network carrier’s footprint and in case you need global connectivity can they offer reliable international coverage? The coverage and reach of the service provider will directly impact issues such as latency, jitter, resilience and cost of the MPLS network.

Network project management and monitoring

Complex networks require constant management to run smoothly. Proactive management can lead to reduced costs and downtimes and enhanced security. Businesses need to understand the details of pricing and the scope of services offered under the head of network management and monitoring services. Do they monitor the entire network? Can they provide managed services to free up IT staff?

Complete MPLS Network Security

Security capabilities of the MPLS service provider need to be scrutinized closely. Businesses need to ensure that service providers are able to support and monitor the entire network closely and provide access to a dedicated security infrastructure including experienced NOC engineers to ensure guaranteed uptime.

Compare SLAs and check references

Another surefire way to assess the capabilities of the service provider is to check the SLAs (Service Level Agreements) offered. While experienced service providers with tested capabilities are usually willing to back their services with SLAs, it pays off to compare SLAs of several MPLS network providers. It is also helpful to look at their existing clients and check references to evaluate their performance.

Class of Service and Quality of Service

Businesses need to evaluate and understand the classes of service (COSs) offered by the carrier. How the carrier consolidates and prioritizes various traffic types will affect the Quality of Service (QoS). It is important that these COSs match your business requirement and the contract with the service provider clearly defines and states these service commitments.

While the above mentioned points form a base to shortlist the right MPLS network provider, other points, such as routing protocols, staff expertise, 3^rd party partnerships, network architecture and future scalability capabilities, must also form a part of the decision making process.

Although cost always plays a big role in any business decision, alignment to your business’ current and future needs and long-term goals should be the deciding factor. After all, your MPLS Network will form the backbone of your business for a long time to come.

Sify Technologies is uniquely positioned to cater to the MPLS Virtual Private Network (VPN) connectivity requirements of Large & Emerging Enterprise customers through its SiteConnect™ services which enable cost-effective converged network solutions that enable point to point data, voice and video traffic.

New-age network architecture and design for Intelligent Network Services

In response to emerging trends and the fast-changing IT landscape, organizations need to rethink network architecture and design strategies to drive digital transformation. It becomes quite critical to align network capabilities in accordance with the changing business requirements and modern topologies. In this light, some of the expectations from Intelligent Network Services are the following:

• Support the fast-changing set of users, applications, devices, and services and unify them intelligently for top-tier user and application experience
• Seamlessly connect between distributed IT assets and applications in a DC and hybrid multi-cloud environment
• Leverage Software and other functionalities to control, rather than physical access and distributed policy control
• Leverage the cutting-edge technologies and algorithms to collect, assimilate, analyze, and visualize networking information in real time for better visibility and control

To achieve the above objectives, there are 3 broad aspects that the IT leaders must follow while designing and architecting the new-age network architecture.

Rationalize, Scale, and Manage your network effortlessly.

In today’s technologically advanced era, enterprises across realms have complex ICT environments – virtual and geographically spread. The advent of Cloud and rise of multiple solution providers globally have encouraged organizations to pick and choose the perfect mix to host their applications, servers, and data across a diverse landscape of Data Centers and multiple clouds. This has benefitted organizations worldwide, in terms of ease of operations, higher level of flexibility and better speed to market. However, at the same time, one must acknowledge that management of such a highly complex ICT environment has become a major challenge for many organizations in the digital era.

Organizations must understand that all the components of their diverse IT and network infrastructure – consisting of applications, servers, machines, network peripheral equipment, sensors, or even distinct Cloud environments – are not discrete or isolated units anymore, but a part of a larger organization context, making them extremely valuable for business progression and business continuity. All these components must be unified and viewed in a consolidated way for better performance and security. That’s where, Network Consolidation becomes imperative!

Organizations that have complex ICT environments face distinct challenges that hamper their overall performance and efficiency. Some of the most common challenges in this changing and ever evolving Network and IT environment are:

• Multiple service providers management: Modern enterprises leverage a perfect blend of best-of-breed network solutions from distinct service providers as this ensures advantages of redundancy, resiliency, choice of network media, and connectivity to remote locations. However, managing all the distinct service providers is quite a challenging task and has some inherent problems, such as lack of ownership and visibility, inconsistency in services, inability to leverage analytics, and governance related risks.
• Limited in-house network management capabilities: This is another major concern for organizations across industry verticals. If they opt for establishing an in-house network management setup, then it becomes a very cost-intensive decision to hire the skilled workforce, procure the technology, develop the competence, and achieve a high level of scalability. Furthermore, an in-house setup would need hefty and timely investments to keep pace with evolving technology landscape.
• The demand for constantly re-architecting network: Every enterprise network nowadays has a host of different applications, which has given rise to changed traffic patterns. These mission-critical applications demand uninterrupted collaboration and traffic exchange, which calls for a continuous re-architecting of network to connect data, applications, people, and varied components of the IT infrastructure.
• Shift of focus from Network uptime to Application performance: Traditionally, network has always been uptime-focused, however in current situation where applications are hosted in multiple of Data Centers, Public & Pvt Clouds, businesses are more concerned about how applications perform over the network as this directly impacts the end user experience. The changing demands of high-performance computing and fast cloud migrations have led to a change in paradigm for networks with their SLAs being evaluated on Application intent rather than Network intent. Therefore, new-age networks must capably meet the rising needs of all mission-critical applications that are running concurrently.
• Unification of underlay and overlay networks: To meet changing demands of businesses, networks have grown and evolved organically over different periods of time. This has resulted in complex architectures of underlay & overlay networks. With changing priorities of organizations and rise of application-focused networks, it is important to unify the underlay and overlay networks for optimal utilization, enhanced efficiency, improved user experience, and robust security.
• Connectivity across DC and Cloud landscape: With increased Cloud adoption, it is very important to maintain a perfect sync between data centers and Cloud. Therefore, they need an excellent Network Interconnection that can guarantee seamless connectivity across all the data centers, Cloud environments, international cable landing stations, third party telco infrastructure, etc. for deterministic connectivity and extensive reach.
• Integration of IT, OT, and People: Majority of organizations nowadays have geographically distributed offices, where employees and end users use multiple devices in different regions. It is important to allow them secure and fast access to applications in Cloud and data centers for better experience, collaboration, and organizational efficiency. At the same time, the same Network must ensure seamless connectivity of IT Infrastructure as well as OT assets like WiFi access points, IoT devices and sensors. Herein, network plays an important role in integration of all aspects of IT, OT, and people.

As discussed above, organizations with complex ICT environments face distinct challenges. This not only hampers efficiency and performance but also impacts end user experience, hence compelling organizations to revisit their network strategies. Enterprises want actionable information to be available to end users wherever they are. The rise in mobility and multitude of devices has paved way for direct access to corporate information, which highlights the need of secure and consolidated network which can be scaled rapidly on-demand. The CIOs need to have complete visibility of all network assets and take decisions on network performance and network behavior dynamically. This can be achieved only through network consolidation.

Consolidating your network under one trusted service provider will ensure you a centralized real-time visibility and control over your entire network. Network consolidation improves network performance management and makes network provisioning easier with lesser handoff points between providers, devices, and IT assets, at a reduced cost!

Network consolidation becomes a very complex task and it has a lot of parameters and moving parts to be looked into. Therefore, it is imperative to seek an expert guidance in this quest.

AWS cost optimization is an ongoing process. AWS cloud resource utilization needs to be continually monitored to determine when the resources are being under-utilized or not being utilized or idling to reduce the costs by deleting/terminating/freeing the unused resources.

It’s also helpful to consider the Saving Plan or Reserved Instances to ensure full utilization as per the anticipated constant level of consumption.

While the fundamental process of cost optimization on AWS remains the same – monitor AWS costs and usage, there are a number of tactical ways to analyze the operational data to find the opportunities for savings and take actions to realize the savings.

Pillars of Cloud Cost Optimization

1. Right-Sizing

Identify the resources with low-utilization and reduce the cost by stopping or rightsizing.

• Use AWS Cost Explorer Resource Optimization report to get the list of idle or low utilized resources. Reduce the costs by either stopping or downsizing the instances.
• Use AWS Compute Optimizer for downsizing recommendations within or across instance families, upsizing recommendations to remove performance bottlenecks and recommendations for EC2 instances that are parts of an Auto Scaling group.
• Identify Amazon RDS, Amazon Redshift instances with low utilization and reduce the cost by stopping (RDS) and pausing Redshift outside of business hours or non-processing timeframe.
• Use Amazon EC2 Spot Instances to reduce EC2 costs where possible – SPOT instance mgmt. can be effectively managed by 3rd part tool, such as Spotinst, for automatic termination and new instance availability without impacting end users.
• Review and modify EC2 Auto-Scaling Groups configuration to ensure scaling is happening on the right thresholds instead of setting it at the lower thresholds.
• Try using Elastic Kubernetes Services (EKS) and Elastic Compute services (ECS – EC2 Model) worker nodes under auto-scaling using SPOT instances (instead of on-demand/RI) for reducing the cost.
• Consider using Elastic Compute services (ECS -Fargate) to start the tasks with lower configuration (e.g. 0.5 vCPUs & 1GB RAM) per task and use auto-scaling instead of higher configuration per task.
• Multi-AZs configuration for DEV, test, UAT, or DR environment may not be necessary or useful for RDS, Redis, NAT, or other PAAS services (unless business really requires achieving any objective); therefore, it’s important to design wisely.

2. Instance Family Refresh

Each instance/series/family offers different varieties of computing, memory, and storage parameters. Instance types within their set groupings are often retired as a unit when the hardware required to keep them running is replaced by newer technology.

• Upgrade instances to the latest generation offering lower costs.
• For PAAS services, such as RDS, Redis, ElasticSearch, MSK, use instance type wisely, particularly for pre-PROD or DR and appropriate AZs to scale the instances. It may not require more than 2 AZs even while considering business SLAs. Keep an eye on the latest family of infrastructure and refresh to take the benefits of lower costing.
• Use low costing instance type for Development, QA, or the environment (e.g. T3a) wherein performance benchmarking certainly is not required for the business SLA.
• Always start with low and upgrade the right size to a suitable family considering the business use cases and traffic patterns.

3. Compute Savings Plans to reduce EC2, Fargate and Lambda costs

Compute Savings (Compute Savings Plans and EC2 Instance Savings Plans) Plans automatically apply to EC2 instance usage regardless of instance family, size, AZ, region, OS or tenancy, and apply to Fargate and Lambda usage. Use one year, no upfront Compute Savings Plans to get a discount of up to 54% compared to On-Demand pricing. Once you sign up for Savings Plans, your computer usage is automatically charged at the discounted Savings Plans prices. Any usage beyond your commitment will be charged at regular On-Demand rates. Please follow Point Nos. 1 and 2 before adopting Saving PLAN. Saving Plan has a lot of advantages over AWS Reserved Instances with one condition – “Usage commitment/Hour”

4. Reserved Instances (RIs)

Even though the Saving plan supersedes the RI option, some of the PAAS services are outside of the Saving Plan program as of today in April 2020.

• Purchase reserved nodes for RDS, Redshift, Elasticsearch and ElastiCache Services to reduce the cost.
• Many instance type discounts are larger and at the top end may be over 60% in the case of some 3 year all upfront terms. Identify the instances & take call saving plan vs RI intelligently.
• You can get shorter term RIs on the marketplace.

5. Scheduling on/off times

It’s worth scheduling on/off for non-production instances used for development, staging, testing, and QA as it can save up to 65% of running these instances if you apply an “on” schedule of 8.00 a.m. to 8.00 p.m. from Monday to Friday. However, it’s possible to save a lot more — especially if development teams work in irregular patterns or irregular hours. Plan more aggressive schedules by analyzing utilization metrics to determine when the instances are most frequently used or apply an always-stopped schedule which can be interrupted when access to the instances is required.

6. Orphaned resources

Identifying waste takes time and accurate reporting. It is a great reason to invest time and energy in developing a proper tagging strategy to make this an easy process.

• For unutilized AWS EC2s, use Cost Explorer Compute Optimizer report or extract CW stats and take actions.
• Terminate VMs that were spun up for training or testing.
• Delete unattached EBS volumes – Check Volumes page and available EBS volumes status.
• Delete obsolete snapshots and lifecycle as required to meet the business demand.
• For idle load balancers, try to use ALB with path/content-based routing.
• Release unattached Elastic IP addresses.

7. Storage

• EBS volumes that have very low activity (less than 1 IOPS per day) over a period of 15 days indicate that they are probably not in use. Identify these volumes using the Trusted Advisor Underutilized Amazon EBS Volumes Check. To reduce costs, first, snapshot the volume (in case you need it later), and then delete these volumes.
• Use S3 Analytics to analyze storage access patterns on the object data set for 30 days or longer. It makes recommendations on where you can leverage S3 Infrequently Accessed (S3 IA) to reduce costs. You can automate the process of moving these objects into lower-cost storage tier using Life Cycle Policies. Alternately, you can also use S3 Intelligent-Tiering, which automatically analyzes and moves your objects to the appropriate storage tier.
• Move infrequently accessed data to lower-cost tiers.
• Use S3 One Zone if business SLA allows you to do so.

8. Containerization

Containers can help to get the most out of available computer hardware and software resources which are Lightweight, have start-up time in milliseconds, and require less memory space. Containers help to achieve the scale of the economy by reducing the IT management resources, snapshot size, spinning up applications, reduced & simplified security updates, etc. Containers are a better choice when your biggest priority is maximizing the number of applications running on a minimal number of servers.

9. Local Caching

If data transfer from EC2 to the public internet shows up as a significant cost, consider using Amazon CloudFront. Any image, video, or static web content can be cached at AWS edge locations worldwide, using the Amazon CloudFront Content Delivery Network (CDN). CloudFront eliminates the need to over-provision capacity in order to serve potential spikes in traffic. Use CloudFront when your userbase is geographically distributed.

10. VPC endpoints

Heavy data lifting to S3 from private subnets (e.g. static contents, backup, videos, etc.) require NAT gateway. Use VPC endpoint to reduce the NAT gateway data out the cost and move data securely over the AWS backbone. This will reduce the NAT Gateway data out the cost that occurs to S3.

11. Regional and AZs Cost

AWS AZ and regional cost can be eliminated wisely through right solutioning.

With-in availability zone (AZ)

• Data transfer costs for transferring data in the same region and within the same availability zone are zero, however with one requirement that you must be using a private IP address.
• If you are using a public or Elastic IPv4 address or IPv6 address, data transfer out from EC2 will be charged at 0.01/GB. In the same way, data transfer into AWS EC2 will be charged at 0.01/GB if you are using a public or Elastic IPv4 address or IPv6 address.

Across availability zones in the same region

• Data transfer between AWS services located in the same region but in different availability zones is considered as regional data transfer and is charged at $ 0.01/GB (outgoing data transfer).
• In the same way, data transfer into EC2 from an AWS service in another availability zone is charged at $ 0.01/GB.

This is only true for some AWS services like Amazon EC2, Amazon RDS, Amazon Redshift or Amazon ElastiCache instances, etc.

• Architect your systems so that there is minimal data transfer across AWS regions or availability zones.
• Architect your AWS environment such that data transfer is restricted to within an availability zone or within a region at the most.
• Try to use private IP addresses instead of public or elastic IP addresses wherever possible.
