Reinventing Infrastructure Performance Monitoring for the Cloud

Virtualization (the underlying foundation of a cloud) introduces a set of challenges to how one should monitor the performance of the infrastructure and the applications. These challenges are:

  1. Unlike physical systems that are mostly dedicated to specific applications, virtual systems are both shared and dynamic. This makes inferring the performance of the infrastructure by looking at resource utilization statistics ineffective. Leading edge Infrastructure Performance Management vendors like AppFirst, Akorri, CA|NetQos, Virtual Instruments and Xangati are taking an Infrastructure Response Time approach to this problem that avoids the issues of relying upon resource metrics, and provides a true picture of how the infrastructure is actually performing.
