Monitoring and diagnosing cloud infrastructure

Abstract

At the foundation of any cloud, a public cloud like Azure or Amazon EC2, or a private cloud like the one in Bing or Google, is the cloud infrastructure. It starts with the physical assets like server racks, physical servers, power units, network switches and storage devices. Then it extends to the layer that includes, among other things, hypervisors, virtual switches and networks, and storage clusters. It is not until the infrastructure works that the cloud management software can create and manage cloud services and virtual machines for the cloud tenants, which is the primary goal of any cloud.
