Learn how one of the leading multi-disciplinary integrated private healthcare services providers in southern India, dealt with frequent outages and failures they experienced.

Challenge:

KIMS hospital had Internal facing HIMS application and other in-house application running in an on-premises data-center for approximately 600 users consisting of Administration, Accounts and Finance department, Doctors and pharmacist. They had experienced frequent outages and failures in past few months. Which led to significant loss in the business productivity. KIMS agreed to move the business critical workloads to cloud. They also wanted to achieve the business continuity without much impact on the RPO and RTO.

Solution:

Redington Carried out a thorough assessment of KIMS on-premises datacenter, studied the environment clearly and a detailed inventory list was prepared by having the following parameters in the infrastructure:

• Number of Servers to be moved
• Different types of Operating system and evaluation of security at the operating system level
• Processor and memory required for the application, user concurrency and various utilization levels.
• Storage growth rate, utilization, and configuration
• Methodologies and frequency of backup and restore requirements.

In an application review process, Redington identified the applications could be transitioned based on the buyer’s

• Integration and dependencies points
• Performances of the applications
• Remote access disk consumption and
• The growth rate of the user with a clear road map towards the cloud.

Redington as part of the implementation best practice followed the CIS guidelines throughout the implementation. Effectively using AWS Services like cloud watch and cloud trail to monitor and protect the complete AWS resources, secure the data in motion and at rest, AWS Managed encryption along with key storage and key management. Redington Established a IPSEC VPN Connection between KIMS Datacenter and AWS using the virtual private cloud to enable secure communication between point to point.

Redington had suggested moving 80 percent of the KIMS business critical workload to cloud, KIMS agreed to the same, by using the VM import and export migration service in AWS, the Virtual machines were migrated to the AWS S3 storage and from the S3 storage the EC2 instances were launched. All the EBS Volumes were encrypted so that snapshots of the volumes are also encrypted, to keep up the security in priority as per the KIMS Requirement.

The on-premises environment had no backup and DR strategy in place. On AWS, the Redington Team had configured automatic scripts to create snapshots of every volume and store them in Amazon simple storage service for the nightly backups of data.

10 TB of archival data present in the on-premises SAN storage needs to be backed up to Amazon S3. For backup of this data, cloudberry tool was used to back up to Amazon S3 frequently. Using the Amazon S3 lifecycle policies, the data was moved to glacier to optimize the cost of the storage.

Outcome:

By migrating the workload to Cloud, it helped to achieve the availability of the workload.

By moving to cloud their operation task like monitoring and log analysis and backing up of the data has been automated and reduced their repetitive tasks.

Low cost backup strategy was implemented to protect their data using AWS Storage like S3 and glacier. Comparatively they saved over 60 percent of cost in contrast to proposed on premises backup solution. Additionally, their availability and durability of the backed up data also increased multifold.
