Serverless Migration Path
About This Architecture
Incremental migration from server-based to serverless without big-bang rewrite. Five phases: background jobs to Lambda (-20% cost), API endpoints to API Gateway+Lambda (-40%), RDS to DynamoDB for suitable tables (-50%), frontend to S3+CloudFront (-55%), and final EC2 decommission (-65%). Shows hybrid architecture during transition and cost savings at each phase.
