Cloud Computing Types - Public,Private & Hybrid Cloud |Updegree|:

Cloud computing is a general term for anything that involves the delivery of services hosted on the Internet. These services are broadly divided into three categories: Infrastructure as a service (IaaS), Platform as a service (PaaS) and Software as a service (SaaS).

A cloud service has three characteristics that differentiate it from traditional web hosting:

• It is sold on demand, usually by the minute or hour • It is elastic, a user can have as much or as little of a service as they want at any time • The service is completely managed by the provider (the consumer does not need anything just a personal computer and Internet access).

Important developments in virtualization and distributed computing, as well as the improvement of high-speed Internet access, have accelerated interest in cloud computing.

A cloud can be public or private. A public cloud sells services to anyone on the Internet (currently, Amazon Web Services is the largest provider of the public cloud). A private cloud is a proprietary network or data center that provides services to a limited number of people. Private or public, the goal of cloud computing is scalable, easy access to computing resources and services.

Cloud computing implementation models Services on the private cloud are delivered from a data center to internal users. This model offers the versatility and convenience of the cloud while retaining the management, control, and security common to local data centers. Common private cloud providers and technologies include VMware and OpenStack.

In the public cloud model, a third-party service provider offers cloud service on the Internet. Public cloud services are sold on demand, usually by the minute or hour, although long-term commitments are available for many services. Clients only pay for the CPU, storage or bandwidth cycles they consume. Major providers of public cloud services include Amazon Web Services ( AWS), IBM and Microsoft Azure, Google Cloud Platform. A hybrid cloud is a combination of public cloud services and a local private cloud, with orchestration and automation between the two. Companies can run mission-critical workloads or sensitive applications in private and use the public cloud to handle a load for bursts or peak demand. The goal of a hybrid cloud is to create a unified, automated and scalable environment that takes advantage of all that a public cloud infrastructure can provide, while still maintaining control over mission-critical data. In addition, organizations are increasingly adopting a multi-cloud model or the use of multiple infrastructure providers as a service. This allows applications to migrate between different cloud providers or even operate simult ... https://www.youtube.com/watch?v=Cz3PJTqs-qE
