The Open Group Conference in San Diego last week included a formal cloud computing conference stream on Wednesday, followed in that evening by an unstructured CloudCamp -- which made an interesting contrast. The cloud conference stream The Cloud Conference stream featured presentations on architecting for cloud and cloud security, and included a panel discussion on the considerations that must be made when choosing a cloud solution. In the first session of the morning, we had two presentations on architecting for cloud. Both considered TOGAF as the architectural context. The first, from Stuart Boardman of Getronics, explored the conceptual difference that cloud makes to enterprise architecture, and the challenge of communicating an architecture vision and discussing the issues with stakeholders in the subsequent TOGAF phases. The second, from Serge Thorn of Architect... (more)

Organizations have started to develop service-oriented solutions and many are now leveraging services in their production environments. SOA introduces new technical complexities and challenges and makes testing a critical component of the development lifecycle. Teams need to think about: How do you know if the solution is ready? How do you know that it will scale to accommodate future needs? How do you know that you can actually get the business flexibility that SOA ... (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)
