Overview
Migrated a legacy monolith to a microservices architecture on AWS, reducing infrastructure costs and improving uptime to 99.99%.
The Challenge
A 7-year-old monolithic application was costing $28K/month to run, had frequent outages during peak load, and took 45 minutes to deploy. The engineering team couldn't ship features fast enough due to tight coupling.
Our Solution
We decomposed the monolith into 12 microservices, containerized with Docker, orchestrated with ECS, and provisioned with Terraform for reproducibility. A blue-green deployment pipeline reduced deploy time to under 5 minutes with zero downtime.
Key Features
12 independently deployable microservices
Infrastructure as Code with Terraform
Blue-green deployments with automatic rollback
Centralized logging with CloudWatch and Grafana
Auto-scaling policies based on real traffic patterns
