Cloud computing is when computing services are provided by a company or place outside of where they are being used.It is like the way in which electricity is sent to users: they simply use the electricity that is sent to them and do not need to worry where the electricity is from or how it is made and brought to them.Every month, they pay only for what they used and nothing more. IBM cloud computing is a set of cloud computing services for business offered by the information technology company IBM. IBM Cloud includes infrastructure as a service (IaaS), software as a service (SaaS) and platform as a service (PaaS) offered through public, private and hybrid cloud delivery models, in addition to the components that make up those clouds.
