Adding in-app chat to a B2B SaaS: edge vs managed realtime?

Curious how teams here approached realtime infra. I'm building FluxyChat as a smaller/self-hostable alternative to managed realtime vendors. Stack is: Workers Durable Objects D1 Main idea: one D

An 87MB WordPress plugin broke my Cloud Run deployment, so I built a 1.5MB replacement

I was running WordPress on Google Cloud Run as a side project — testing whether it could work as a horizontally scalable, serverless CMS. Everything ran fine until I needed to offload media uploads to

Lambda@Edge vs CloudFront functions. Edge won.

Spent two weeks optimizing cold starts on our Lambda functions, cut them from 1.8s to 340ms

We ship a React component library as Lambda@Edge for dynamic header/footer injection. Cold starts were killing us in prod, especially during traffic spikes. Started with the obvious stuff: smaller bun

Everyone pretending Lambda cold starts don't matter

The amount of cargo cult "best practices" around Lambda is exhausting. Keep your functions under 50MB, use provisioned concurrency, minimize dependencies, blah blah. Yeah, and sometimes a cold start j
