AWS Serverless Migration

Migrate EC2/S3 apps to serverless: Lambda + API Gateway + DynamoDB event-driven. Schema migration dual-write zero-downtime cutover — saves compute costs 60-80%.

• Event-driven refactoring (SNS/SQS/Lambda)
• DynamoDB single-table pattern design
• Lambda cold-start + provisioned concurrency
• Dual-write validation during migration window
• RTO/RPO dashboard per migrated workload

• 60-80% compute cost reduction vs EC2
• Zero-downtime cutover with dual-write
• Auto-scale 0 to 10k RPS no cluster provisioning
• Serverless ops overhead near-zero
