Speedscale is a Y-Combinator backed startup that helps Kubernetes engineering teams build resilient and performant containerized apps. Our production traffic replication platform is a more reliable, cost-effective, and scalable way to test and deliver cloud-native software applications. Unlike other tools, we use agents/sidecars to record and playback sanitized traffic that you see in prod. With Speedscale, engineers can generate load, simulate production conditions, and mock third party backends modeled after real traffic patterns.

Jeff Kwan, Principal Software Engineer, discusses how and when his team at Cimpress (parent company of Vistaprint) starts preparing for holiday load testing.

A common approach in software is to start small, then move to bigger initiatives, but it's often easier said than done. The theory breaks down in production, which is why devs need new approaches.
