## What it is
Motan is a cross-language remote procedure call (RPC) framework for rapidly building high-performance distributed services, originally developed at Weibo. It provides cluster support, service discovery integration with Consul and Zookeeper, load balancing, and synchronous/asynchronous calls with clients in Java, Go, PHP, and Lua.

## Use cases
- build high-performance distributed services in java
- rpc framework with service discovery via zookeeper or consul
- cross-language rpc between java go php and lua services
- weighted load balancing across data centers
- synchronous and asynchronous remote procedure calls
- microservices communication framework for high load scenarios

## When to choose
- you need a jvm-based rpc framework with mature cluster and service discovery support
- your services span java, go, php, or lua and must interoperate
- you run high-traffic production systems needing idc-aware scheduling and load balancing

## When to avoid
- you want a polyglot-first ecosystem like grpc with broad community tooling
- your stack is not jvm-centric and you don't need motan's specific features
- you need rest/http-first apis rather than binary rpc

## Facets
- artifact type: framework
- maturity: active
- function: rpc, microservices, service-discovery, load-testing, middleware
- domain: microservices, backend, developer-tools
- platform: jvm, cross-platform
- tags: rpc-framework, distributed-services, service-governance, cross-language, high-performance, consul, zookeeper, java
