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 Architecting the Enterprise, looked at the considerations in each TOGAF phase, but in a more specific way. The two presentations showed different approaches to similar subject matter, which proved a very stimulating combination.
This session was followed by a presentation from Steve Else of EA Principals in which he shared several use cases related to cloud computing. Using these, he discussed solution architecture considerations, and put forward the lessons learned and some recommendations for more successful planning, decision-making, and execution.

We then had the first of the days security-related presentations. It was given by Omkhar Arasaratnam of IBM and Stuart Boardman of Getronics. It summarized the purpose and scope of the Security for the Cloud and SOA project that is being conducted in The Open Group as a joint project of The Open Groups Cloud Computing Work Group, the SOA Work Group, and Security Forum. Omkhar and Stuart described the usage scenarios that the project team is studying to guide its thinking, the concepts that it is developing, and the conclusions that it has reached so far.
The first session of the afternoon was started by Ed Harrington of Architecting the Enterprise, who gave an interesting presentation on current U.S. Federal Government thinking on enterprise architecture, showing clearly the importance of cloud computing to U.S. Government plans.
The U.S. is a leader in the use of IT for government and administration, so we can expect that its conclusions that cloud computing is already making its way into the government computing fabric, and that enterprise architecture, instantiated as SOA and properly governed, will provide the greatest possibility of success in its implementation will have a global impact.
We then had a panel session, moderated by Dana Gardner with his usual insight and aplomb, that explored the considerations that must be made when choosing a cloud solution custom or shrink-wrapped and whether different forms of cloud computing are appropriate to different industry sectors.
