linker∙d is a transparent proxy that adds service discovery, routing, failure handling, and visibility to modern software applications.
Linkerd is an open source network proxy designed to be deployed as a service mesh: a dedicated layer for managing, controlling, and monitoring service-to- service communication within an application. It is a resilient service mesh for cloud native apps.
What problems does it solve?
Linkerd was built to solve the problems we found operating large production systems at companies like Twitter, Yahoo, Google and Microsoft. In our experience, the source of the most complex, surprising, and emergent behavior was usually not the services themselves, but the communication between services. Linkerd addresses these problems not just by controlling the mechanics of this communication but by providing a layer of abstraction on top of it.
By providing a consistent, uniform layer of instrumentation and control across services, linkerd frees service owners to choose whichever language is most appropriate for their service. And by decoupling communication mechanics from application code, linkerd allows you visibility and control over these mechanics without changing the application itself.
Today, companies around the world use linkerd in production to power the heart of their software infrastructure. Linkerd takes care of the difficult, error-prone parts of cross-service communication—including latency-aware load balancing, connection pooling, TLS, instrumentation, and request-level routing—to make application code scalable, performant, and resilient.
