Continuous Integration in the cloud: good idea?
The topic of running a CI server in a virtualized environment, such as with Amazon's EC2 service, is an interesting issue, particularly in the Hudson community. About 10 months ago Kohsuke announced the Hudson EC2 plugin which has seen slow, but steady development since then, including support for the Ubuntu Enterprise Cloud which was added to the plugin in a release last Monday.
As The Build Doctor and his readers point out, continuous integration is a difficult task to offload into the cloud because of the immense hardware demands constant building and testing presents. That said, Hudson does very effectively manage spinning slaves up and down on demand if you've configured it as such. Implication being: running Hudson in the cloud may be more efficient to meet peak demands without needing to run a large farm of machines.
Would you run Hudson in the cloud?
