FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -What is cloud computing? Cloud computing is on-demand access, via the internet, to computing resources-applications, servers (physical servers and virtual servers), data storage, development tools, networking capabilities, and more-hosted at a remote data center managed by a cloud services provider (or CSP).

Detailed explanation-2: -According to Microsoft, 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.

Detailed explanation-3: -A cloud delivery model represents a specific, pre-packaged combination of IT resources offered by a cloud provider. Three common cloud delivery models have become widely established and formalized: Infrastructure-as-a-Service (IaaS) Platform-as-a-Service (PaaS) Software-as-a-Service (SaaS)

Detailed explanation-4: -Most cloud computing services fall into four broad categories: infrastructure as a service (IaaS), platform as a service (PaaS), serverless, and software as a service (SaaS). These are sometimes called the cloud computing “stack” because they build on top of one another.

Detailed explanation-5: -Infrastructure as a Service (IaaS) Infrastructure as a Service, sometimes abbreviated as IaaS, contains the basic building blocks for cloud IT and typically provide access to networking features, computers (virtual or on dedicated hardware), and data storage space.
