Application Modernization
Transform legacy monoliths into cloud-native microservices on AWS EKS, Lambda, and Fargate. Automated CI/CD with CodePipeline, blue/green deployments, and event-driven architectures.
Modernization Approaches
Choose the right modernization path based on your application's complexity, team capabilities, and business objectives.
Container-First (EKS/ECS)
Containerize applications and deploy on managed Kubernetes (EKS) or ECS for predictable scaling, portable workloads, and consistent environments.
Reference Architecture:
Serverless-First (Lambda)
Event-driven architectures with Lambda, API Gateway, and Step Functions. Pay-per-execution with zero infrastructure management.
Reference Architecture:
Hybrid (Strangler Fig)
Incrementally extract services from the monolith using the Strangler Fig pattern. Route traffic between legacy and new services with ALB.
Strategy:
- 1. Identify bounded contexts in monolith
- 2. Extract service with anti-corruption layer
- 3. Route via ALB path-based routing
- 4. Gradually shift traffic to new service
- 5. Decommission legacy component
Event-Driven Architecture
Loosely coupled services communicating via events. EventBridge for routing, SQS for buffering, and SNS for fan-out patterns.
Event Patterns:
- • Event sourcing with DynamoDB Streams
- • CQRS with separate read/write models
- • Saga pattern with Step Functions
- • Fan-out with SNS + SQS subscriptions
- • Dead-letter queues for resilience
CI/CD & Deployment Automation
Fully automated deployment pipelines with blue/green, canary, and rolling update strategies on AWS.
AWS CodePipeline
End-to-end CI/CD orchestration with source (CodeCommit/GitHub), build (CodeBuild), and deploy stages. Cross-account deployments with approval gates.
AWS CodeBuild
Managed build service with custom environments, parallel builds, and caching. Docker image builds, unit tests, SAST scanning, and artifact generation.
AWS CodeDeploy
Blue/green deployments for EC2, ECS, and Lambda. Automatic rollback on CloudWatch alarm triggers with traffic shifting controls.
GitOps with ArgoCD
Declarative deployments on EKS using ArgoCD. Git as single source of truth for cluster state with automatic drift detection.
Pipeline Architecture
