Application Migration

Application Modernization Using Pivotal Cloud Foundry

application-modernization

A Fortune 500 Financial Services company needed to modernize their applications so as to be able to deploy to an on-premise PaaS and phase out the expensive legacy platform, to have an elastic infrastructure to meet new business demands and to deliver business capabilities to production in an accelerated manner.

Client Challenges and Requirements

  • Single tests for both Android and iOS platforms
  • Excellent test coverage for Regression and Smoke
  • Non-availability of physical devices for testing
  • Changes in platform versions and compatibility testing due to these changes
  • Cost to maintain apps on legacy platform (WebSphere) was significant
  • Every few years IBM WebSphere forced teams to conduct an expensive migration of  their apps to newer versions to maintain support
  • Infrastructure provisioning for new business capabilities took a long time with extensive planning
  • Delivering business capabilities to production took a long time, typically 12 weeks for even small changes
