From Monolith to Serverless

on YouTube ↗01h 02m

" summary

Migrates a 20‑year ASP/ASP.NET/VB.NET system with many SQL Server instances and zero tests into an evented serverless stack using AWS Lambda, Kinesis, S3, API Gateway and read stores like Elasticsearch/DynamoDB; captures DB changes, validates and tags events, fans them to feature‑specific stores, and serves a React SPA. Claims move from six‑monthly releases to continuous delivery with ~10‑minute deploys, testing lambdas in‑memory, daily dev tear downs, and a demo built in 230 lines of code that costs $0.40/month for 2M lambda calls.
