SOA and Cloud Computing: Are They The Same?
SOA has been a buzzword in enterprise computing for a while. Cloud computing is relatively new one but gaining stronger momentum than SOA. With these two terms, many people get a little confused: is cloud computing just a new name for SOA? And can they play together?
Definitions
Before drawing a conclusion, let’s take a look at the definitions from wikipedia.org:

Cloud Computing: is Internet-based computing, whereby shared resources, software and information are provided to computers and other devices on-demand, like a public utility.

In my previous blog, I mentioned cloud as architecture pattern (CAA), which can be leveraged in enterprises as well. If we compare the SOA and CAA, they look somewhat similar and share some core principles:
