Cloud computing is the on-demand access of computing resources—physical servers or virtual servers, data storage, networking capabilities, application development tools, software, AI-powered analytic tools and more—over the internet with pay-per-use pricing.Cloud computing plays a pivotal role in our everyday lives, whether accessing a cloud application like Google Gmail, streaming a movie on Netflix or playing a cloud-hosted video game.The cloud computing model offers customers greater flexibility and scalability compared to traditional on-premises infrastructure.
A private cloud is a cloud computing environment dedicated to a single organization. In a private cloud, all resources are isolated and in the control of one organization. So, the private cloud is also called the internal or corporate cloud.
Public cloud computing is a model where a third-party provider manages and hosts servers, storage, and applications for the public. The public can access these services over the internet on demand, and pay for them as they go.
A community cloud in computing is a collaborative effort in which infrastructure is shared between several organizations from a specific community with common concerns (security, compliance, jurisdiction, etc.),
A hybrid cloud—sometimes called a cloud hybrid—is a computing environment that combines an on-premises datacenter (also called a private cloud) with a public cloud, allowing data and applications to be shared between them.
