Application delivery services are critical for successful applications. Whether such services add scalability, reliability, or security, most applications rely on one or more. Application Delivery Controllers (ADCs), therefore, occupy a critical place in most application, cloud, and data center designs.
But what does "performance" actually mean? In general, ADC vendors publish four main types of metrics to demonstrate performance:
Requests per second (RPS) Connections per second (CPS) Transactions per second (TPS) Throughput (often measured in gigabits per second, Gbps)

The SVM provides an aggregated view of the detailed findings from NSS Labsí group tests. Individual PARs are
available for every product tested. CARs provide detailed comparisons across all tested products in the areas of:

Empirical data from our individual Product Analysis Reports (PARs) and Comparative Analysis Reports (CARs) is used to create the unique Security Value MapTM (SVM).
The SVM provides a quick, clear overview of the relative value of security investment options by mapping security effectiveness and value (TCO per protected-CPS) of tested product configurations.
So far, most data centers have virtualized their least-critical workloads as a matter of basic cost containment. Virtualizing mission-critical applications is still forthcoming for the majority,though, largely due to infrastructural concerns. Complicating matters is the shift in IT purchasing decisions from IT to business management.
Integrated Computing Platforms (ICPs), private cloud computing, and public cloud services all leverage virtualization to achieve a number of IT and business goals, including increased ROI, reduced OpEx, and business process improvement. Now more than ever, it makes sense to explore the benefits of ICPs.
