Today, global businesses are increasingly turning to Service Oriented Architecture (SOA) for their information technology infrastructure and applications. SOA is becoming an increasingly practiced approach to building software solutions as it can support integration and consolidation of activities in complex enterprise systems. This year the percentage of functioning SOAs has almost doubled, according to Evans Data Corporation's latest Web Services development survey: "Twenty-four percent of respondents (the sample data set being 400) are saying they currently implement SOA, an 85% increase from last year." The survey also shows that Web Services are now experiencing more comprehensive implementation, with 30% of respondents predicting they will be using more than 20 services in the next year - a 58% increase from current levels. Twenty-five percent of respondents ... (more)

Testing SOA Solutions

Service Oriented Architecture (SOA) has been discussed as an important architectural style for the last few years. Organizations have started to develop service-oriented solutions and many are now leveraging services in their production environments.

Counting the Cost of Cloud

IT costs were always a worry, but only an occasional one. Cloud computing has changed that. Here's how it used to be. The New System was proposed. Costs were estimated, more or less accurately, for computing resources, staff increases, maintenance contracts, consultants and outsourcing. The battle was fought, the New System was approved, the checks were signed, and everyone could forget about costs for a while and concentrate on other issues, such as making the New System actually work. One of the essential characteristics of cloud computing is "measured service." Resource usage ... (more)

A Peaceful Leap to Cloud Computing

History has many examples of invaders wielding steel swords, repeating rifles, or whatever the latest weapon may be, driving out people who are less well-equipped. Corporate IT departments are starting to go the same way, at the hands of people equipped with cloud computing. Recently I was at The Open Group conference in Boston. The Open Group is neutral territory with a good view of the IT landscape: An ideal place to watch the conflict develop. The Open Group Cloud Computing Work Group has been focused on the business reasons why companies should use cloud computing. The Work Gro... (more)
