What is the Linkerd service mesh?

Service meshes, like Linkerd, address a core challenge faced by engineers building modern "cloud native" applications today: adding and maintaining critical security, reliability, and observability features to their microservices applications without changing any code.

Its core value is that it decouples the platform team from its reliance on the developer teams, providing critical observability, security, and reliability features at the platform level. And it does that in a way that is uniform and consistent across all microservices—regardless of language, framework, or team. Beyond adding consistency and uniformity to the platform, Linkerd allows each team to focus on its job: the platform team on delivering a reliable, secure, and scalable platform for the developers; and the developers on implementing the fundamental business logic of the application.
