Windows Azure - What is an Extra Small Instance?
During a presentation today, people were discussing the various sizes of Windows Azure compute instances. Small, Extra Small, Large, Medium etc. I have provided the table below for quick reference. Windows Azure compute instances come in five sizes to enable complex applications and workloads. Each Windows Azure compute instance represents a virtual server. Although many resources are dedicated to a particular instance, some resources associated to I/O performance, such as network bandwidth and disk subsystem, are shared among the compute instances on the same physical host.
