SCloud services are designed to provide easy, scalable access to applications, resources and services, and are fully/partly managed by a cloud services provider. A common analogy to describe cloud computing is renting versus buying. Essentially, you rent capacity (server space or access to software) from a cloud service provider and connect over the internet. Instead of buying your own IT requirements, you are renting from a service provider, paying for only the resources you use.
