Apache Etch provides is a cross-platform, language- and transport-independent RPC-like messaging framework.
Etch is a cross-platform, language- and transport-independent framework for building and consuming network services. The Etch toolset includes a network service description language, a compiler, and binding libraries for a variety of programming languages. Etch is also transport-independent, allowing for a variety of different transports to be used based on need and circumstance. The goal of Etch is to make it simple to define small, focused services that can be easily accessed, combined, and deployed in a similar manner. With Etch, service development and consumption becomes no more difficult than library development and consumption.
