Monitoring and Diagnosing Cloud Infrastructure

Wojtek Kozaczynski, Microsoft

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.

Cloud infrastructures get large very quickly and countless things can, and do, go wrong in them. One of the fundamental questions is how to monitor and diagnose those infrastructures so that when something goes wrong, we can either take a corrective action immediately or prevent the same fault from happening again.

Every data center must provide some level of monitoring and diagnostics, so there is no shortage of often very creative custom and point solutions. Most, if not all, of those solutions deploy custom agents to compensate for lack of monitoring functionality in the bottom layers of the cloud infrastructure and the OS.

So what do we need to put natively in those bottom layers to create a foundation for scalable, resource efficient monitoring and diagnostics solutions?
