Since the VMs are trapped on physical machines in this approach, first-generation providers dictate cookie-cutter sizes that make that stacking game easier for themselves. In the process, though, these providers can't do anything to ... (more)

Cloud: Performance Matters, Benchmarking Saves Comparing cloud providers is complicated. With constant price drops and the frequent introduction of new instance types, no matter what answer you come up with today it is sure to change in three months.
