Once the apps have been migrated, IT needs to continue to monitor the cloud for changes or deviation of
baselines to determine if more resources are required. In some cases, resources can be dynamically applied at
certain times of the day to keep up with peak demands, then released when those peak times have passed, making
those resources available for other applications.
Leveraging virtualization in the cloud enables organizations to dynamically reallocate or move virtual machines
(VMs) to resources when needed. However, moving VMs to different resources can present problems for IT in terms of
maintaining visibility of the VM and assessing the impact of the move, because some tools will treat a moved VM as
new and history can be lost.
Solving the cloud management conundrum
Enterprise IT organizations leveraging private and off-premises public cloud services face several additional
performance management challenges:
" Cost containment -- Collecting, monitoring and baselining performance across technologies is critical to
allowing IT to right-size environments based on the needs of the services they support and deliver, therefore
optimizing or maximizing their infrastructure investments.
" Timely notification -- Baselines are essential because IT must rapidly identify changes in performance
behavior. Business dissatisfaction is a big problem and when performance issues arise due to an increase in
application usage, proactive notification allows IT to dynamically reallocate resources to ensure SLAs are met.
" Traffic management -- Analyzing usage data allows IT to better architect and plan for new services. They need
to understand where they can reduce costs through virtualization and convergence of infrastructure, while also
enabling leading edge delivery models supported by usage-based accounting.
" Triage -- When problems arise, IT needs the visibility to quickly identify where within the cloud performance
of key business services is affected.

For IT, the primary objective is managing the infrastructure and connectivity and ensuring that the bandwidth of
the latter is sized appropriately so that SLA commitments on performance and resource availability can be met. The
ability to on-board new business applications and end users rapidly is a necessity, meaning a single performance
management platform is vital if IT organizations are to avoid the cost and complexity of having to deploy and
configure multiple systems and then aggregate performance data back to a single point to achieve end-to-end
