writes "Our CTO has asked us to move our entire dev/test platform off of shared, off-site, hardware onto Amazon, Savvis or the like. Because we don't know enough about this, we're nervous about the costs like CPU: Jenkins tasks checks-out 1M lines of source, then builds, tests and test-deploys 23 product modules 24/7; as well, several Glassfish and Tomcat instances run integration and UI tests 24/7. Disk: large databases instances packed with test and simulation data. Of course, it's all backed up too. So before we start an in-depth review of what's available, what experiences are dev shops having doing stuff like this in the cloud?"
