Cloud Computing Quick read

Context:  With rising pandemic pushing people to work remotely has contributed  to a long-term trend of rising demand in cloud computing 

  • Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale. 
  • There are three different ways to deploy cloud services: on a public cloud, private cloud or hybrid cloud.
    1. Public clouds are owned and operated by a third-party cloud service providers, which deliver their computing resources like servers and storage over the Internet
    2. A private cloud refers to cloud computing resources used exclusively by a single business or organisation. A private cloud can be physically located on the company’s on-site datacenter.
    3. Hybrid clouds combine public and private clouds, bound together by technology that allows data and applications to be shared between them.
