The problem is that not everything is as black and white as security folks desire. If we implement performance and other management tools, we often need to expose part of our all important virtualization management network to others. But how do we do this safely, securely, with minimal impact to usability? Why do we need to this is also another question. You just have to take one look at the Virtualization ASsessment TOolkit (Vasto) to realize the importance of this security requirement. But the question still exists, how do you implement other necessary tools within your virtual environment without impacting usability?
VMware has combined resource monitoring, capacity management, configuration management, with the self-learning analytics that came from Integrien into vCenter Operations – creating an attractive bundle of functionality for the management of the performance and capacity of vSphere environments.
The right approach to monitoring a virtual or cloud based environment is to start with a clean sheet of paper, determine your requirements, and assemble a horizontally layered solution out of best of class vendor solutions that address each layer. Vendors should be evaluated on their mastery of one or more layers, their ability to keep up with the change in that layer, and their ability to integrate with adjacent layers.
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.
Self-learning performance management solutions like Integrien and Netuitive are going to be absolutely an essential part of the migration to dynamic data centers and IT as a Service. Once these dynamic data centers scale out to the thousands of applications in a typical enterprise, and scale up to address the most performance critical applications, the rate of change in the environment will be too high for legacy tools and manual administration to be able to keep. up. These automated self-learning approaches will be the only way in which IT Operations will be able to stay on top of these new environments while staying within staffing and budget constraints.
While VMware has articulated the need for a management strategy and has provided some building blocks for its management stack, there are currently and will be for the near term future significant gaps in the VMware management offerings even when the domain of the problem is constrained to the management of the VMware platform. Once the domain is expanded to include the physical infrastructure which underlies the virtualization platform, and once it is again expanded to include multiple virtualization platforms the use case is outside of what VMware intends to provide. For these reasons, third party solutions should be considered for each component of the diagram above when evaluating solutions from VMware.
