Software as a Service (SaaS) is a mainstream way of bringing enterprise applications to hundreds of thousands of application users at a stable cost. Rather than loading client software on a desktop PC, we lease software from the cloud, and monitor how the SaaS application is delivered. That makes it available to everyone in the enterprise.

Salesforce.com is an essential mission-critical application for many enterprises. Because it is only delivered through the cloud, its performance is highly dependent upon where it is being served from, accessed from, end-to-end network characteristics and type of usage within in an enterprise.
