What is still missing here is any kind of an end-to-end view of infrastructure latency that is also real time, deterministic and comprehensive. The marrying of the SAN point of view with the IP network point of view is the obvious combination. The hard issue here will be the identification of the applications so that these view of infrastructure performance can be surfaced on a per application basis. In summary, we have a long way to go here, and this just might be why so many of those virtualization projects for business critical and performance critical applications are having so much trouble getting traction.
Applications Performance Profiling is an essential step in the process of virtualizing business critical and performance critical applications. In this case “performance” means response time not resource utilization. The virtualization team should go even further and commit to meeting response time based SLA’s for business and performance critical virtualized applications.
Attempting to infer the performance of a database server by looking at resource utilization metrics will fail technically and organizationally. In a shared and dynamic environment, the only way to truly assess the performance of an element of the infrastructure or an application is to measure how long it is actually taking to do its job. This makes response time and its companion metric latency into the two most important metrics for virtualized and cloud based systems.
VMTurbo has delivered a new free vSphere performance and capacity management solution that is neither time nor size of environment limited, and that breaks new ground in terms of capacity management functionality delivered in a free solution. The automatically generated VM Rightsizing Recommendations should prove to be of particular value to vSphere administrators.
BMC has acquired Coradiant the leader in web applications performance management. Now it remains to be seen if BMC will follow up this step with additional steps to create a modern monitoring stack suited for virtualization and the cloud, or if BMC will under-utilize Coradiant’s assets by simply integrating Coradiant with its legacy systems management framework.
It is also interesting to speculate what long term role the Hyperformix statistical modelling technology will play in CA performance management and performance assurance products. VMware has puts its stake in the ground via the acquisition of Integrien that only a real time and self-learning approach will be able to keep up with variability inherent in a virtualized or cloud based system in order to provide effective root cause analysis. It is possible that over time this modelling technology will evolve into a real time self learning performance management capability analogous to what is p; provided by VMware/Integrien and Netuitive. If this occurs this will mean that CA will be the first and only one of the big four systems management vendors with an effective root cause strategy for the new dynamic data center.
