situation

NCR's backend services handled 10K+ req/min through an aging REST-only API layer on GKE. High-frequency service-to-service calls had throughput bottlenecks, the gateway infrastructure needed modernizing, and the platform required FedRAMP compliance to support government contracts.

challenge

Migrate 20-30 REST APIs to a new gateway platform without disrupting live traffic, improve throughput on critical high-frequency paths, and achieve FedRAMP compliance - all while maintaining on-call availability for the services throughout the transition.

solution

Adopted gRPC for high-frequency service-to-service paths, cutting REST payload overhead and improving overall performance 30%. Migrated 20-30 APIs to Apigee X on GCP as the unified gateway layer. Profiled and load-tested to target the highest-impact bottlenecks first. Implemented FedRAMP compliance controls across the microservices platform.

KEY CONTRIBUTIONS

  • Adopted gRPC for high-frequency service-to-service paths - reduced REST payload overhead and improved throughput 30%
  • Migrated 20-30 REST APIs to Apigee X on GCP as the unified gateway layer without service disruption
  • Implemented FedRAMP compliance controls across the microservices platform for government contract eligibility
  • Profiled and load-tested bottlenecks to prioritize the highest-impact migration targets
  • Owned on-call availability throughout the migration, triaging failures and restoring service via pod-level remediation
