Hi platform peeps! Anirudh took some time to write about using OpenTelemetry and service mesh to fundamentally change how dev environments, testing, and staging all work. The idea is 'request isolation' and means using a much more accurate cluster to do all our testing and experimentation. From the article:

For each new dev/test/preview environment, we only deploy “what changed” [...], which is often a small number of microservices in comparison with the overall number, and share any unchanged dependencies with the baseline environment.
