How Uber & DoorDash empower developers to preview every code change in production
The blog post discusses the challenges faced by Uber and DoorDash in their quest for efficient testing in production. Uber, dealing with unreliable end-to-end tests and conflicts over staging environments, developed SLATE (Short-Lived Application Testing Environment) to create on-demand ephemeral testing environments. This improved isolation and developer velocity. On the other hand, DoorDash, striving for faster feedback, adopted a new approach to preview features in the production Kubernetes environment, enhancing their product development process.
