started as a means for server consolidation in order to obtain better
efficiency in IT infrastructure. Cost savings came from increased system
utilization and reduced server hardware needed to support multiple workloads. However,
as private clouds were increasingly deployed in modern data centers, there has
been a sharp increase in the number of Virtual Machines that are managed. Many
of these clouds have been architected with a hypervisor model supporting many
operating system copies. This model actually creates issues of poor efficiency and
high management overhead. In other words, IT managers are back again looking at
the issue of how to improve the efficiency in their clouds.
This blog entry describes how Oracle's layered virtualization model, and state-of-the-art life-cycle management, provides the ideal foundation for building efficient private clouds.
