How SOA Fits into Cloud Computing

Prof. Paul A. Strassmann, George Mason University 2010 SOA Symposium April 22, 2010

FY2011 Spending for I.T.

2 SOURCE: http://www.whitehouse.gov/omb/e-gov/

Note: I.T. spending does not include costs of >150,000 soldiers & civilians, or >$15 Billions

Will I.T. Increase as the Base Budget Declines?

57% of I.T. Costs Are in an Expensive Infrastructure

What Are the Primary Benefits of SOA?

•  Discover Data from a Data Registry; •  Discover Applications Anywhere; •  Mediate the Extraction of Data from Data Bases; •  Execute Requests from Multiple Servers; •  Provide Credentials Validation to Everyone.
