Software as a Service (SaaS) is a model that has become a popular choice for deploying enterprise applications, delivering efficiencies and value to organizations in many ways. The benefits SaaS solutions deliver include not only avoiding the major resource drain and licensing costs associated with deploying business-critical software across the organization, they also relieve IT from ongoing maintenance tasks associated with on-premise deployments, such as performing upgrades, installing patches and managing availability. Moreover, SaaS can enhance flexibility and scalability for enterprise applications and workloads. Of course, while these benefits gained from adopting SaaS solutions in the enterprise are significant, they must nevertheless be balanced against potential risks. In particular, consideration must always be given as to whether cloud applications are sufficiently secure.
