" 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.
RESOURCES: 5 cool tools for cloud management
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 visibility.
Meanwhile, end users will also expect the enterprise IT team to be able to deliver end-to-end visibility on performance and quality of the application services if they are to justify their cloud investment. Although SLAs can be hard to enforce within a unified fabric scenario, moving forward, it will be essential for enterprises to have the right tools to be able to quickly isolate and resolve issues before they result in major business interruptions.
Cloud computing and virtualization indeed are transforming the way in which IT is delivered and consumed. But as adoption continues to rise, organizations require a unified view of network, server and application performance across physical and virtual infrastructures to meet current SLAs and future demands.
