GOAL: New Workload Delivered in Under One Hour
is still in the early stages of maturity.
Yet there are some expectations that, if not met, will break the back of
IT. Four expectations emerge as
critical. Reliability is expected to 100%. Enough backup, but not too much, is required
to deliver “Always available” reliability.
Resiliency is expected to be fail proof, so that there is no break in
service if any component in the system fails.
Speed and agility are expected to be transformed so that new workloads
can be delivered in as little as one hour, rather than days or weeks. And self-service is a critical
component. End users expect to be able
to deploy and manage their own resources so that the delivery of IT resources
Users of IT resources now have the opportunity to use a credit card and get cloud-delivered workloads themselves. This might meet their short-term needs, but does little to help IT control costs and resources, or provide any kind of IT governance. So delivering resources "at the speed of cloud" is not only responsible but imperative.
The cost advantages of cloud computing -- public, private or hybrid --
are astounding. However, it requires a shift in IT thinking and
strategy: from managing hardware and software, to delivering workloads
in a dynamic environment (IT-as-a-Service).
The Risk of the Cloud is Diversity and Redundancy. If all of your backups and Raid and tapes etc are all in one data center the risk and possibility of losing everything in 1 giant disaster goes up.
