Cloud computing is a new edge technology and it continues getting the momentum that makes system administrators look for more ways to integrate with Cloud framework. Cloud users can establish the connection with their resources through the three Cloud delivery models, such as – Software-as-a-Service (SaaS),
Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS).
Connecting Cloud users to their resources need mapping WAN-to-server requests and the protocols that determine how the resources (server and
storage) are selected for a certain Cloud user.
