Faster time to market. If an application development team requires five servers to be online in hours, the server team can provide the appropriate resources
without having to provision new physical servers.
High availability and workload balancing. With cloud computing, when the systems management tools determine that the infrastructure supporting an application is about to go down, they can automatically launch a new virtual machine and shift the load to it.
Ability to maintain control over data and regulatory environments. Private cloud computing brings together the benefits of public cloud computing while still enabling an organization to maintain control over its data, including where it is physically located, who can access it, and the physical security profile. This control also enables customers to more closely adhere to regulatory constraints for data locality, disaster recovery, and privacy.
Ability to provide consistent support and service-level agreements (SLAs). With private cloud computing, IT organizations can apply business process– based SLAs to ensure that mission-critical applications continue to operate in the event of an outage, while tier 2 and tier 3 applications can continue to be supported in a more cost-effective environment.
Driving New Levels of Policy Management in the Datacenter
While cloud computing is enabling — and, in some instances, forcing — organizations to change their approach to technology deployment, organizations must also change
the processes and policies governing their technology deployments. In addition to the technology benefits cloud computing provides, it can also be a strong catalyst for driving best practices in policy management. For example, when datacenters made the transition to VMs, many relaxed their policies for requesting and approving server deployments because they assumed that VMs were "practically free." This contributed to the VM sprawl we see today. Organizations are starting to reel their processes back in, requiring justification and approval for deploying new VMs, much like they did with physical servers. Having to justify the need for new servers makes sense, whether those servers are physical or virtual.

own systems integrator, purchasing servers, storage, networking, and management software and performing an implementation project to deploy and integrate these technologies. Dependencies and risks had to be identified and evaluated, tasks and project plans had to be assembled and executed against, and change management had to be put in place.
