Cloud Computing: As Service or As Architecture?
Last week I saw an incoming link at my blog site from privatecloud.com, a website promoting private cloud computing inside enterprises backed by EMC. Due to curiosity, I browsed the website and found a video by VMware CEO Paul Maritz on cloud computing. BTW, my website is also featured at the home page. Thanks privatecloud.com!
In the video, Paul talked about the cloud computing, mostly referring to services over the Internet, can also be an architecture pattern for enterprises. When that architecture is implemented, you will have a private cloud on premise. Although not using cloud services from any service provider, you still get almost all the benefits in a private cloud.
From the system architecture perspective, your applications built within a private cloud aren’t much different than those built using external cloud services. If both of the services follow the same interface spec, your application may switch between public cloud and private cloud either statically or dynamically.
