Going Full Silo - Using Serverless to Build for Dev Simplicity

on YouTube ↗17m

" summary

Company builds wearable barcode scanners and runs a serverless multi-tenant backend by deploying the full stack into separate AWS accounts per customer, giving 3,500 AWS accounts with roughly 200 Lambdas per account (north of 600,000 functions total) and about 70 million events/month. CI creates per-PR sandbox accounts, runs the full test suite there, and then deploys through staged pipelines; architecture reduces accidental cross-tenant access and makes developer sandboxes identical to production while increasing observability and account-management complexity.
