Customer Business Needs:

Oxigen was running their three mainstream business applications in on-premise setup in a hybrid model of physical and virtual machines.

The infrastructure hardware was nearing its end of life. The fact that they had both B2B and B2C applications, they were looking for a public cloud platform which can support the growth based on the user base that might potentially get added in the near future.

Rapyder worked with Oxigen to do a complete assessment of their on prem deployment.

As part of the assessment conducted, the following points were deduced:

  1. Total Cost of Ownership by moving to AWS
  2. Migration strategy
  3. Migration plan and wave planning

As part of the migration, 90+ servers across 10 applications were moved to AWS.
A detailed operating model was setup with monitoring and backup needs.

  • AWS Dedicated hosts were used for provisioning of EC2 instances.
  • Direct Connect and site to site VPN was implemented from AWS to connect to the partner banks for the applications.
  • AWS VM Import/Export was used to move custom VM files to AWS for OEMS,B2B,B2C and PCI application.
  • Route53 is used for the DNS configuration.
  • All Software licenses, including Microsoft Windows and SQL Server, were under BYOL agreement, which is used as per the application’s need on the instances in Dedicated hosts. This helped in bringing the cost further down.
