云端的一个关键特色是它能够通过增减计算能力来满足变化的需求，提供有弹性的可伸缩性。
A key characteristic of the cloud is its ability to offer elastic scalability by easily increasing or decreasing compute power to meet changing demand.
这些需求包括系统审核与控制、可扩展性、弹性、垂直伸缩性和水平伸缩性、多站点问题以及第三方工具的集成。
These requirements include system audit and control, extensibility, resilience, vertical and horizontal scalability, multisite issues, and integration of third-party tools.
如果采用专有技术，也许为了解决可伸缩性或弹性需求，可以添加服务网关组件以提供Web服务连接性。
If a proprietary technology is adopted, perhaps in order to address scalability or resilience requirements, a service Gateway component could be added to provide web services connectivity.
