Cloud Computing is a term that many people, particularly in the SME sector find confusing. The reality is that if you’ve been using it for years without even realising it. Hotmail, Facebook, Dropbox, Google Apps, and iTunes are all examples of Cloud computing. There are countless others you’ve probably used as well.
Simply put, Cloud Computing describes a service that delivers computer resources over the Internet. These services can include software, data storage, or data processing.
The reason this is called ‘Cloud Computing’ is because traditionally the symbol used to represent the Internet on the diagrams used by IT professionals was a Cloud.
There are 3 Cloud Models. These are: Software as a Service (SaaS); Platform as a Service (PaaS); and Infrastructure as a Service (SaaS)
There are 3 Cloud Types: Public, Private and Hybrid.
