The role of Software as a Service in cloud computing

The role of Software as a Service in cloud computing: "Want to know what role Software as a Service (SaaS) plays in cloud computing? Explore different flavors of SaaS, and see two examples of how SaaS works in cloud computing—namely, plant engineering management and distance learning—in the pay-on-demand infrastructure environment. Tune SaaS for optimal performance by combining the best of two worlds: multi-tenancy and virtualization. Discover solutions to the problems of unused resources and interoperability. And finally, understand that without proper planning and implementation, the costs of security safeguards can far outweigh the economic advantages of SaaS and cloud computing."
