If there is one thing that has caused revolution in the IT industry, then its Cloud Computing. Cloud Computing refers to the use of processing resources and data on demand while typically paying only for what you use and for the period you use. Cloud Computing can be further differentiated based on the offering by different vendors viz. Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service(IaaS).
Amazon Web Services, Microsoft Azure, IBM Cloud, VMWare, Oracle Cloud, Salesforce.com and many more are leading the way how Infrastructure is provisioned on-demand and how apps are deployed on that Infrastructure. Beyond this, several Cloud platfroms offer significant out-of-the-box services which make development faster and reliable.
