Windows Azure is Microsoft's application platform for the public cloud. Recent addition of Infrastructure as a Service (IaaS) offers a powerful way for developers and DevOps to take advantage of the benefits of cloud computing by allowing them to provision infrastructure resources (CPU, memory and network) on the fly. These resources are typically priced per hour and you only pay for what you use. Best of all, these resources are only a service management API call away. Thus making it very interesting for developers and DevOps alike.
