Anchored lifecycle platforms

Although anchored platforms have most of the same characteristics as theintegrated lifecycle platform, there is one key difference: These environmentshave a packaged business software at the core.

bilities may be a specific tool.

For example, although Amazon.com provides a comprehensive IaaS platform,it also offers platform tools such as SimpleDB and Simple Query Service(SQS). Other enabling technology environments (such as Rightscale) providean integrated management platform designed for the cloud. Hyperic, a divi-sion of Springsource (recently acquired by VMWare), offers a cloud-basedmonitoring environment. WaveMaker lets users customize their platform andallows developers to reuse existing code within the PaaS environment. Thereare testing-based and social networking-based services as well.

The following sections in this chapter take a closer look at these three typesofPaaS. To do this, we look at some of the key vendors that provide thesecapabilities. Clearly, there are many other players besides the ones we listhere, and there will be even more before this book is even published. Ourgoal is to give you an understanding of how each of these PaaS approachesworks.
