Introduction
What is Cloud Computing?
According to Wikipedia, Cloud Computing is a paradigm for enabling network access to a scalable and elastic pool of shareable physical or virtual resources with self – service provisioning and administration on demand. In other words, Cloud Computing is the delivery of computing services over the internet on – demand. It allows users to pay for only the services they use and offers benefits such as faster innovation, flexible resources and economics of scale.
Cloud Computing allows you to rent instead of buy your IT. Rather than investing heavily in databases, software and hardware, companies opt to access their compute power via the internet or the cloud, and pay for it as they use it.
There are four types of computing and then there are three types of cloud computing services. The four types of computing include, Private clouds, Public clouds, Hybrid clouds, and Multiclouds.
The three types of cloud computing services include Infrastructure- as – a – service(IaaS), Platform – as – a – service(PaaS), and Software – as – a -service(PaaS).
