Overview
This project involved migrating a suite of critical aviation operations systems from traditional on-premises infrastructure to a modern, serverless architecture on AWS.
Key Outcomes
- Performance: 40% improvement in response times through optimized architecture
- Cost: 50% reduction in infrastructure costs through right-sizing and serverless compute
- Reliability: 99.99% availability achieved through multi-AZ deployment
- Agility: Deployment frequency increased from monthly to multiple times per day
Architecture Highlights
The migration followed the Strangler Fig pattern, allowing us to incrementally move functionality while maintaining system stability. Key architectural decisions included:
- Event-driven processing using Amazon SQS and Step Functions
- API-first design with Amazon API Gateway
- Serverless database with Aurora Serverless for variable workloads
- Comprehensive monitoring with CloudWatch and X-Ray
