How we migrated our Android endpoints out of a monolith into a new microservice by Rohan Dhruva , Ed Ballot As Android developers, we usually have the luxury of treating our backends as magic boxes running in the cloud, faithfully returning us JSON. At Netflix, we have adopted the Backend for Frontend (BFF) pattern : instead of having one general purpose “backend API”, we have one backend per client (Android/iOS/TV/web).

Chaos Mesh is a cloud-native chaos testing platform that orchestrates chaos in Kubernetes environments. While it's well-received in the community with its rich fault injection types and easy-to-use dashboard, it was difficult to use Chaos Mesh with end-to-end testing or the continuous integration (CI) process. As a result, problems introduced during system development could not be discovered before the release.
