The effects of deploying virtualization technologies reach far beyond the parts of the infrastructure that are being virtualized by altering the roles of traditional infrastructure components. Virtualizing servers and desktops changes how organizations go about providing IT services, but also changes how the performance of IT services is being managed across the entire delivery chain. Sixty-two percent of organizations that participated in TRAC's recent survey reported that lack of visibility across the IT service delivery chain is one of the key challenges for managing IT performance in virtualized environments. As a result, organizations are increasingly realizing that ensuring optimal performance of their networks becomes even more important once they have virtualized their infrastructure. Furthermore, managing network performance in virtualized environments requires network management systems (NMS) to be enhanced with a new set of capabilities so they can address key challenges of virtualization management.
This report from TRAC Research analyzes the impact of virtualization technologies on network management and examines capabilities that are becoming increasingly important in virtualized environments.

Some of the key reasons for the proliferation of cloud services and virtualization technologies in the enterprise are measurable business benefits, such as improved flexibility of managing computing resources, decreases in operating cost and total cost of ownership (TCO). Many management vendors recognized this opportunity and enhanced their product portfolios with capabilities for managing the performance of virtualization and cloud technologies. However, only a few of these vendors are actually offering management products that are based on virtualization technology or using SaaS as a delivery method. So this brings up the following question: If organizations can achieve significant business benefits from virtualization and the Cloud when managing their computing resources, can they achieve similar benefits from using these technologies for managing the performance of IT and business services?
The changes in the economic climate that happened in late 2008 and 2009 forced organizations to take a hard look into their IT spend and find areas where they can cut cost and still be able to support the needs of end-users. Some of the main areas that many of them identified where:
- They were paying for management capabilities that they were not using
- They had computing resources that were underutilized
- Their operational cost for managing IT performance was too high

Over the last 2-3 years, the term “Application Performance Management” (APM) became an integral part of marketing messaging for more than 70 technology vendors. Even though solutions provided by all of these vendors are helping to improve the speed and availability of business-critical applications, these vendors are providing solutions that are significantly different. These solutions could range anywhere from network performance monitoring to application acceleration, Web management and even managed/carrier services.
However, the APM as a general concept has become relatively easy for decision makers of end-user organizations to digest, as it hits all key pain points that IT organizations are dealing with. As a result, multiple vendors were more than happy to jump on this bandwagon and position themselves as players in this space.
Other than the language in their press releases and marketing collateral, these vendors really have nothing else in common. Technology wise, how similar are the offerings of F5, NetQoS, Keynote Systems and OpTier? They are not similar at all.
