At its simplest, cloud computing is "the delivery of computing services over the internet ('the cloud')... computing services cover a range of categories, including servers, storage, databases, networking, software, and analytics." Rather than having your own physical data centers and hard drives, you can access computing technology through cloud computing service providers like Amazon Web Services, Microsoft Azure, or Google Cloud. How It Works: The "Rental" Model Think of cloud computing like a utility, like electric or water service. You don't have to have your own power plant to flip on a switch and see a light bulb turn on. You simply "rent" electric service based on how much you use it. https://www.iteducationcentre.com/best-network-cloud-computing-classes-in-pune
