Federal Reserve Bank of Saint Louis: Migration to GovCloud



Federal Reserve Bank of Saint Louis requested support in reviewing the architecture and roadmap for the migration of the e-Invoicing application to a cloud environment.  The application was described as a highly complex architecture with technology implementations requiring expertise in application, database, and security to understand, design and develop an AWS Gov Cloud roadmap and level of effort estimate. The goal was to provide Client the ability to evaluate its options for continued use of the system after sunsetting its data center.


Client engaged UNCOMN to assess their proposed environment and architecture design. UNCOMN was to help Client establish a cloud-based environment for continued operation of a critical application after on-premises datacenter shutdown.  Cloud resources were to allow for rapid deployment and high scalability without significant change to the existing application.


  • Identified several areas where meeting FIPS compliance requirements was not possible in original architecture
  • Recommended Blue/Green deployment design
  • Provided sample Cloud Formation Templates (with in-line comments) for FRB use
  • Identified concern with CIDR block assignment
  • Existing maturity of on-premises automation using WebLogic Scripting Tool (WLST) demonstrated a mature team and a solid head start on automation in cloud environments.
  • FRB goals for containerization and server less technologies will ultimately position the enterprise for more supportable and resilient solutions in the future.
