VIRTUALIZATION REACHES BEYOND THE HYPERVISOR
Virtualization admins' top concern is no longer choosing a hypervisor -- it's choosing the right suite of tools that will help with overall virtualization management, improve VM performance, make capacity predictions, and enable self-service IT and rapid provisioning. This chapter explains the latest challenges of managing a virtualized infrastructure, with insight into particulars tools to improve virtualization and cloud management. Virtualization technology has changed the way servers are purchased and deployed, but effectively monitoring and managing these virtualized environments is no small challenge. More and more, IT infrastructure companies are looking beyond the hypervisor to help users solve virtualization management challenges and to assist them in operating virtualized and cloud environments in a cost-effective manner. For instance, tools that allow chargeback and showback can help a business to track which units are consuming particular resources and to tally the associated costs.
Virtualization has been widely implemented, and its merits are well-established. But organizations realize that monitoring and managing a virtualized environment requires sophisticated tools that aid capacity planning, provisioning and configuration management. Major hypervisor vendors and IT infrastructure companies are working hard to differentiate their management tools from the competition.
