Explore a comprehensive conference talk on managing multiple development environments within a single Kubernetes cluster. Dive into advanced techniques for implementing service mesh, event routing, and data isolation to support stable, branch-specific, and release candidate environments. Learn how to leverage Istio virtual services, create dynamic event subscriptions, and handle database migrations safely. Discover the benefits and challenges of ephemeral environments, and gain insights into optimizing your development workflow. Understand the cognitive load implications and potential drawbacks of this approach while exploring solutions to common issues in multi-environment setups.
