Go kit is a programming toolkit for building microservices
(or elegant monoliths) in Go. We solve common problems in distributed
systems and application architecture so you can focus on delivering

Go has emerged as the language of the server, but it remains underrepresented
in so-called "modern enterprise" companies like Facebook, Twitter, Netflix, and
SoundCloud. Many of these organizations have turned to JVM-based stacks for
their business logic, owing in large part to libraries and ecosystems that
directly support their microservice architectures.
To reach its next level of success, Go needs more than simple primitives and
idioms. It needs a comprehensive toolkit, for coherent distributed programming
in the large. Go kit is a set of packages and best practices, which provide a
comprehensive, robust, and trustable way of building microservices for
organizations of any size.

the motivating blog post and

- Operate in a heterogeneous SOA — expect to interact with mostly non-Go-kit services
- RPC as the primary messaging pattern
- Pluggable serialization and transport — not just JSON over HTTP
- Operate within existing infrastructures — no mandates for specific tools or technologies
- Supporting messaging patterns other than RPC (for now) — e.g. MPI, pub/sub, CQRS, etc.
- Re-implementing functionality that can be provided by adapting existing software
- Having opinions on operational concerns: deployment, configuration, process supervision, orchestration, etc.

Thank you, contributors!
Go kit is modules aware, and we
encourage users to use the standard modules tooling. But Go kit is at major
version 0, so it should be compatible with non-modules environments.
There are several third-party tools that can generate Go kit code based on
different starting assumptions.
