Cloud computing is the delivery of computing services — servers, storage, databases, networking, software, analytics and more — over the Internet (“the cloud”). It is a type of internet-based computing that provides shared computer processing resources and data to computers and other devices on demand. It employs the use of remote servers over a network. These servers can provide functionality like storage, processing, security, analytics etc. delivered in a pay-per-use basis. Cloud computing works by storing data off the device, then retrieving the data when needed using an Internet connection, thereby consuming large amount of scarce bandwidth.
Fog computing is a decentralized computing infrastructure in which data, compute, storage and applications are located somewhere between the data source and the cloud. Like edge computing, fog computing brings the advantages and power of the cloud closer to where data is created and acted upon.
Edge computing pushes computing power to the edges of a network, implementing data analytics close to the end devices and close to the source of data.
Major Cloud Computing Service Providers are Microsoft Azure, AWS (Amazon Web Services), Google Cloud Platform, IBM Cloud, VMware. These are available as Infrastructure as a service (IaaS), Software as a service (SaaS), Platform as a service (PaaS), etc.
Google Cloud and Boston Consulting Group (BCG) in a joint study released in Feb. 2020 said that India continues to show potential for rapid growth in public cloud. Projected to grow at a CAGR of 25% from US$3 billion in 2018 to US$8 billion in 2023, public cloud deployments in India have the potential to contribute approximately US$100 billion in GDP cumulatively from 2019 to 2023 according to the study.
