The widespread implementation of virtualization and the acceleration of the adoption of cloud computing are changing the economics and operations model for managing IT infrastructure. Higher utilization of shared infrastructure is dramatically reducing the "per unit" costs, and business agility is being enhanced because organizations now have the ability to deploy IT infrastructure resources on-demand when needed.
While the business benefits of the new approach are undeniable, IT teams are facing a daunting challenge in ensuring the effective performance of the entire IT infrastructure that supports an organization's critical business services and processes. Within the new IT environment, business services and processes are often enabled using a diverse mix of in-house and external infrastructure and services.
A business application in a cloud environment may be dependent on the effective functioning of external application services, function-specific virtual machines, shared storage and dedicated physical servers. Additionally, a variety of communications links and network nodes may also be part of the supporting infrastructure.
So, how can IT teams effectively monitor the performance of all these interrelated resources in such a complex environment and, more importantly, how can they ensure the smooth functioning of dependent business services and processes?
