SOA正在帮助企业做从自动执行商务流程到提高灵活性等一切事情。但是，实施这种技术并不是一件简单的事情。由于对稳定性、安全性和技术支持消失等问题的担心，开源软件已经成为企业级IT的一个主要成分。开源软件能够像专有的解决方案一样稳定、安全和能够得到技术支持，如果不是说更好的话。
SOA is to help enterprises do from the automatic execution of business processes to improve flexibility and all other things. However, implementation of this technology is not a simple matter. Due to the stability, safety and technical support to vanish. Worry, open source software has become an enterprise IT is one of the main components. Open source software as proprietary solutions like stability, security and able to receive technical support, if not to say the words. (2012-07-11, PDF, 400KB, 下载4次)
