Keeping Virtualization Under Control

Arthur Cole

If the heady rush of virtualization is starting to give way to the headache of managing all that vapor, take heart: New breeds of management systems are making it easier to launch, optimize and retire virtual machines.


The chief culprit in the battle to maintain control over virtual environments is virtual sprawl. Now that the top virtualization vendors have perfected the art of provisioning and launching virtual environments, the need is growing for automated processes to retire those environments when they are no longer needed. Without effective management, the steady growth of virtual systems, which demand the resources of real hardware nonetheless, can become light years more serious than the physical sprawl that virtualization was supposed to combat in the first place.


I found a good run-down on issues surrounding virtual sprawl by Embotics' David Lynch here. He offers a number of key insights into how to tell when virtual sprawl is getting out of hand (it's not just the number of VMs being created), how it can negatively affect enterprise functionality, and the key elements in managing virtual lifecycles.


Many of the top vendors are already building out their virtualization management capabilities. Last month, we saw Microsoft unveil its Systems Center Operations Manager 2007 Cross Platform Extension, which not only keeps track of both virtual and physical systems, but extends this capability across multiple, non-Windows platforms like HP-UX, RHEL and Solaris.


This week sees the release of VMware's IT Service Delivery Bundle, aimed at full automation of VM lifecycles for use in IT service applications. The system provides for self-provisioning of VMs, as well as more extensive control over virtual environments by preventing sprawl through lifecycle management. The goal is to provide a more effective means to deploy IT services by minimizing risk to the enterprise and automating the development, testing and deployment of virtual environments.


Business software firm SAS is offering its own take on management of the VMware environment with the new IT Intelligence for VMware Infrastructure system. The idea was to bring business intelligence and analytics technology into VMware's VirtualCenter management system to not only automate many of the management tasks at play, but to predict the future needs of the environment and ensure resources are available to meet them.


In a similar vein, Tideway Systems is bringing its expertise in application dependency mapping (ADM) to virtual management in its Foundation 7.1 system. Traditional ADM systems offer a window into what types of applications are running at a given time, as well as how they are affecting server environments, storage and even other applications. Tideway tweaked its system to offer the same thing for virtual machines in VMware, Sun and now IBM AIX environments.


Effective management is the key to a smooth-running operation. Once you trade the physical world for a virtual one, the art of management becomes a greater challenge because the symptoms of an overloaded environment often don't present themselves until the situation reaches critical mass. If Job 1 was to get virtualization in place, Job 2 should be to develop the means to control it.

You should also consider the facts that (a) nearly every data center will have multiple VM and container technology before long... so you need a cross-technology mgmt approach, and (b) that you won't be virtualizing everything... so we'll need a solution that pulls managing VMs and workloads across Physical & Virtual realms too. There are some nice Physical-to-virtual conversion tools from Platespin, and nice cross-technology physical & virtual automation tools from Cassatt. Reply
