Etch was an open source, cross-platform framework for building network services, first announced in May 2008 by Cisco Systems.[1] Etch encompasses a service description language, a compiler, and a number of language bindings. It was intended to supplement SOAP and CORBA as methods of communicating between networked pieces of software, especially where there is an emphasis on portability, transport independence, small size, and high performance. Etch was designed to be incorporated into existing applications and systems, enabling a transition to a service-oriented architecture. It was derived from work on the Cisco Unified Application Environment, the product acquired by Cisco as part of the Metreos acquisition.


The mid-2008 release was planned to supported Java and C#. A second wave of support was supposed to include Ruby, Python, Javascript, and C.[1]

In July 2008, Etch was released under the Apache 2.0 license.

As part of the open source process, Etch was submitted to the Apache Incubator to be accepted as a new podling.[2] On August 25, 2008, the formal vote was proposed[3] and was eventually passed. In September 2008 Etch entered the start-up phase within the Apache Incubator.

The last update of Apache project was in 2011, since the project never got out of the "incubating phase".[4] Cisco announced the Unified Application Environment had its "end of life" on February 8, 2012.[5]
