Customer Business Needs:
Medi Assist was running their TPA production workloads on-premise, consisting of a combination of Linux and Windows-based environments.
Mediassist customer base is increasing rapidly, and they needed a public cloud platform that could scale according to the user traffic without any manual intervention or delays in infrastructure procurement.
Business Solution:
Rapyder worked with Mediassist to assess their current application and infrastructure landscape, and a detailed plan was created for migrating their applications to AWS concerning cost, security, and scalability.
As part of this, around 25 applications running across 70+ servers were migrated in a lift-and-shift fashion to AWS. Also, high-traffic facing applications were deployed across availability zones with autoscaling to ensure high availability.
Solution Provided To The Customer:
- Implemented a robust approach for deployments, rollbacks, and database replication for all the applications.
- Connectivity from AWS to on-premise was established using a site-to-site VPN.
- Palo Alto Firewall was deployed in high availability across Availability zones from AWS Marketplace for gateway firewall services.
- Route53 was used for the DNS configuration.
- All Software licenses required for SQL Server were brought into AWS under the BYOL agreement, reducing migration costs significantly.
- Servers were set up in MultiAZ High Availability/Cluster structure.
- Microsoft Active Directory was hosted in a shared account of AWS and will be synced with On-Prem AD.
- AWS LCM was used for backup (AMI) with the RTO and RPO requirements of the customer.
- The Rapyder team has suggested recommendations based on Well-Architected Review, which will be remediated soon, along with Mediassist.
