In Kubernetes environments, concerns like retries, security, observability, and traffic control often end up scattered across application code, leading to duplicated logic, inconsistent behavior, and systems that are harder to operate and debug. The service mesh was designed to solve exactly that.
In this episode, David talks with William Morgan, co-founder and CEO of Buoyant, about the origins of the service mesh ...
