What is Cloud Computing?

What is Cloud Computing?

Cloud Computing means storing and accessing data and programs over the Internet instead of your computer’s hard drive. The cloud is just a metaphor for the Internet. Cloud computing is a game-changer in the Information Technology world and the way we utilize compute services, especially the small and medium businesses. 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.

Types of Cloud Computing-

Public cloud

Public clouds are owned and operated by a third-party cloud service provider, which delivers their computing resources like servers and storage over the Internet. With a public cloud, all hardware, software and other supporting infrastructure are owned and managed by the cloud provider. You access these services and manage your account using a web browser.

Private cloud

A private cloud attributes to cloud computing resources handled exclusively by a particular business or organization. A private cloud can be physically located on the company’s on-site datacenter. Some companies also pay third-party service providers to host their private cloud. A private cloud is one in which the services and infrastructure are maintained on a private network.

Hybrid cloud

Hybrid clouds blend public and private clouds, connected by technology that allows data and applications to be shared between them. By allowing data and applications to move between private and public clouds, a hybrid cloud gives your business greater flexibility, more deployment options and helps optimize your existing infrastructure, security, and compliance.

Types of Cloud Services-

Infrastructure as a Service (IaaS)

The most basic category of cloud computing services. IaaS contains the basic building blocks for cloud IT. It typically provides access to networking features, computers (virtual or on dedicated hardware), and data storage space. IaaS gives you the highest level of flexibility and management control over your IT resources.

Platform as a Service (PaaS)

Platform as a service point to cloud computing services that provide an on-demand environment for testing, developing, managing and delivering software applications. PaaS is designed to make it easier for developers to quickly create web or mobile apps, without worrying about setting up or managing the underlying infrastructure of servers, storage, network and databases needed for development.

Software as a Service (SaaS)

SaaS provides you with a complete product that is run and managed by the service provider. Users can connect to a rented app over the Internet, usually with a web browser. All of the underlying middleware, infrastructure, app data, and app software are placed in the service provider’s data center. The service provider handles software and the hardware and with the relevant service agreement to ensure the security and availability of the app and data.
