Things that they must consider are design, implementation and administration.  If an organization is concerned about scalability and they want a quick implementation they will probably choose a public cloud model. Whereas if they are concerned more about security and would like the cloud managed internally and they arent concerned about scalability then they would more than likely consider a private cloud option. However, if security and scalability are both concerns of the business, they some sort or hybrid cloud option might be the best option.  Cloud computing and infrastructure are the most important factors is the IT community because they have similar roles and different similarities. For example, cloud computing is known for its ability to provide system resources as needed. But cloud infrastructure is known for the software and hardware components that are used, which include the servers, repositories,  networks, and software that provide the virtualization.
