The answer is C: Enablement of application as SaaS.
A cloud can provide IT infrastructure network services like storage and servers. Once an application has been identified as a potential candidate for cloud migration, it is important to consider what type of cloud environment; PaaS, SaaS, or IaaS. In this case, SaaS will be considered. SaaS host business application and makes them available to clients online. It removes the need for enterprises to run applications on their own.
