Go Micro is an open-source framework for building distributed systems and microservices in Go. It provides abstractions for common service concerns such as RPC, service discovery, messaging, configuration, encoding, transport, and client/server communication so applications can use consistent interfaces across different infrastructure choices.

The framework emphasizes pluggable components, allowing developers to swap implementations for registries, brokers, stores, transports, and other underlying services. This approach keeps application code focused on service behavior while the framework handles recurring patterns associated with networked Go applications.

Go Micro is intended for developers building service-oriented systems who want more structure than assembling every distributed-systems primitive independently. It can be used to standardize communication and infrastructure patterns across multiple Go services while preserving flexibility in the concrete technologies deployed underneath.
