Software as a service offerings are expanding, and gaining more acceptance. How would you like to just stop deploying enterprise software, stop monitoring application performance, and stop participating in the finger-pointing and second-guessing which occurs when there are performance problems? That's the basic attraction of software-as-a-service (SaaS).
Customers access SaaS applications and data via the Web and essentially rent the application from the SaaS provider on a per-user or per-month basis. The SaaS provider is responsible for delivering, securing and managing the application, data and underlying infrastructure.
SaaS sounds good, but you need to also consider the main trade-off: Someone else will be responsible for your organization's application performance and for safeguarding your corporate data. Is your organization ready to make that kind of trade-off?
