ABSTRACT:
A new wave of virtualization-related technologies has emerged that address these challenges and improve upon the efficiency and value of virtualization. Native virtualization is a new approach that improves performance, reliability and total cost of ownership. New virtualization solutions that leverage open source hypervisors derived from the Xen open source project offer users choice and minimize the risk of proprietary lock up. Additionally, hardware-assisted virtualization, now available in new processors from AMD and Intel, enable high performance virtualization without modification to operating systems.
With these new capabilities, a truly dynamic IT infrastructure is emerging -transforming the static, hard-wired data center into a software-based, dynamic pool of shared computing resources. These new solutions provide simplified management of industry standard hardware and enable today's business applications to run on virtual infrastructure without modification. Using centralized policy-based management to automate resource and workload management, they deliver "capacity on demand" with high availability built in.
