Virtual infrastructure management challenges: VM sprawl and security
This article is part of the Virtual Data Center issue of June 2009, Vol. 11
Virtual infrastructure management involves the concerted use of automation, monitoring and management tools to keep hardware and software running effectively. Virtualization allows virtual machines (VMs) to run on any virtualized server hardware in any suitable rack or blade chassis, where administrators could easily identify the email server or locate mission-critical database servers. The hypervisor's ability to disconnect the software and hardware creates virtual infrastructure management challenges, making it more difficult for IT administrators to monitor the resource demands of VMs, gauge their performance and perform capacity planning in a timely manner. These virtual infrastructure management challenges only worsen as VMs proliferate across the enterprise. Organizations routinely use software tools to identify, evaluate and monitor the server resources available in the virtualized data center. Management challenges of a virtual data center Virtualization brings a number of benefits to the enterprise, but it also brings a...

Virtual infrastructure management gets more complicated as virtualization proliferates. VM sprawl and security pose some of the biggest management challenges.
Physical server virtualization isn't the end of a virtualization project. These eight critical postvirtualization tasks, including host server patching, monitoring virtual machine sprawl and exploring backup options, can help to ensure an efficient, healthy and secure virtual environment. An expert explores these tasks in this tip.
