You went serverless, deployed Lambda, and then watched your RDS instance die under 10,000 simultaneous connections. I've been there. RDS Proxy saved my backend - here's how!
AWS sneaked a feature into Lambda in 2022 that lets you call functions directly via HTTPS — no API Gateway required. I've been saving hundreds per month with it. Here's how.
If you're copy-pasting the same utility code and npm packages across 30 Lambda functions, your deployment zips are a disaster and your sanity is next. Lambda Layers fix this — here's everything I wish I knew earlier.
Your Lambda chaining logic looks like my college codebase — a mess of callbacks, error handlers, and prayers. Step Functions exists specifically so you never have to write that again.
I once chained 7 Lambda functions together with async callbacks and SNS triggers. It worked great — until it didn't. Step Functions turned my distributed spaghetti into a debuggable, visual workflow. Here's everything I learned building e-commerce order flows with it.
I scaled Lambda to handle 10x traffic and watched our RDS instance die in real-time. Turns out each Lambda invocation opens its own DB connection — and RDS has a limit. Here's how RDS Proxy saved our e-commerce backend from connection hell.

Your Lambda functions are calling each other in a tangled mess of async chaos? After years of architecting serverless workflows on AWS, here's how Step Functions saved me from callback hell and $500/month in wasted Lambda executions!
