Microservices Migration Platform

Healthcare Technology Provider

Challenge

A healthcare company needed to migrate from a monolithic architecture to microservices while maintaining HIPAA compliance and zero downtime during the transition.

Solution

We designed and implemented a microservices architecture using Express.js for each service, with centralized authentication, encrypted communication, comprehensive audit logging, and gradual traffic migration using feature flags.

Results

  • 12 microservices deployed
  • Zero downtime during migration
  • Full HIPAA compliance maintained
  • 70% improvement in deployment frequency
