Virtualization has helped to improve hardware efficiency
through consolidation of servers. It has also significantly lessened the time
needed to launch a server online; today, you can do this in a matter of hours
instead of having to wait for weeks to bring it online. This advantage has
given businesses a lot of agility but with every new improvement, there are
always issues to deal with. If these issues are not addressed right at the
start, it may end up eating into the overall efficiency of a virtual
infrastructure. Many virtual servers are being provisioned without any proper
justification or approval. Some continue to consume resources even when they
may no longer be needed. It becomes necessary to deal with these management
challenges and control the virtual servers. IT managers feel that the virtual
server sprawl can be controlled through the same processes or auditing measures
which are employed for physical servers. So, whenever a new server gets
requested it is important to evaluate the needs for it to find out whether it
is really needed or it is being installed just for convenience. Industry
watchers recommend using a server life-cycle management method through which a
virtual server’s use and status right from creation to expiry gets tracked.
