How to reduce pain during development on a microservice architecture
The pains of developing on microservices (debugging, local dependencies, slow deploys, costly mocks) and fixes that help, such as Lyft's routing of test requests through shared staging.

Integration/E2E TestingIs WASM the future for Kubernetes Operators?
What WebAssembly offers Kubernetes operators, a walkthrough of building and deploying a WASM filter for Envoy with Istio, and the reasons for skepticism about WASM on the server.

The struggle for developers to collaborate on microservices
Why features that span several microservices are hard to build and test together, where subsets, Docker Compose and namespaces fall short, and why a service mesh that routes test requests helps.

Integration/E2E TestingOpenTelemetry and Go: a whole new eBPF world
How eBPF brings automatic OpenTelemetry instrumentation to Go services without code edits, and how the project kept it stable across changing structs, stripped binaries and monotonic time.
