There are several good diagrams retrievable from Google Images that show the infrastructure of cloud computing. For a few good diagrams that show, explain, and provide details on its growth all from a single source, check out the Web site at http://abacuscloudcomputing.com/content/Cloud-Resources/cloud-computing-diagrams.html.

For a discussion on cloud computing, there is a blog posted at a site called NetStart Project (http://netstartproject.com/blog/cloud-computing/). Anyone can join in on the blog conversations by leaving a reply and clicking on the "Submit" button. To learn more about the "cloud," hence the cloud represents the Internet, cloud computing, and the three primary types of clouds, take a look at the blog from Dave McCrory (http://community.hyper9.com/blogs/h9labs/archive/2009/10/27/cloud-computing-explained-part-2.aspx) who claims to be a cloud-computing expert.

On the Internet, there are several Web sites that talk about cloud computing. Just type in “cloud computing” at any search engine site to retrieve several pages on the subject. One site in particular that is both reputable and seems to always provide good articles and information on topics is InfoWorld. On their Web site, there is an article, “What cloud computing really means” (http://www.infoworld.com/d/cloud-computing/what-cloud-computing-really-means-031) that explains this technology in detail. Another site with great answers on cloud computing are posted at Mahalo’s site (http://www.mahalo.com/answers/are-there-any-online-courses-offered-for-cloud-computing), which provides responses to questions (like this one) on the topic; plus, explains where people like you can learn more about it.

Cloud Computing Companies states that Cloud architecture, the systems architecture of the software systems involved in the delivery of cloud computing, typically involves multiple cloud components communicating with each other over a loose coupling mechanism such as a messaging queue. Elastic provision implies intelligence in the use of tight or loose coupling as applied to mechanisms such as these and others.
