Cloud computing can be well interpreted as an expanded feature of the internet that facilitates users with a "cloud of on-demand computing resources such as servers, storage space, and even data centers" on a pay-per-use basis. The cloud service has three main characteristics: it's available on-demand, usually by the hour or the minute; it allows users to utilize as much and as little of service according to the need; and it is entirely managed by a thirty-party service provider. A personal computer with internet access is all you will need to access the cloud from anywhere and at any given time.

Types of Cloud Infrastructure
A cloud can be public, private or the combination of both (known as the hybrid cloud). Public cloud is open for anyone on the internet, whereas private cloud infrastructure is exclusively for a single company. Public or private, cloud computing is entirely focused on providing users with easy, scalable and fast access to IT services and computing resources. When it comes to Hybrid cloud, it is composed of multiple clouds (public or private) that serve as individual entities, providing the advantages of multiple deployment models.

There are three types of cloud computing services: Saas (Software as a Service), PaaS (Platform as a Service) and IaaS (Infrastructure as a Service). SaaS runs on remote computers that are owned by others and connect to your computer through the internet and a web browser. PaaS establishes a virtual environment that has everything needed to support the entire lifecycle of developing and providing cloud applications, devoid of complexity and cost of purchasing and updating underlying software, hardware and hosting. As far as IaaS is concerned, it renders the clients with computing resources such as storage, servers, data centers, and networking services on a rental basis.

Key Benefits of Cloud Computing service
Cloud computing maximizes the effectiveness of shared resources. The resources are not only shared among multiple users but also re-allocated according to the demand. This feature of cloud is greatly helpful in allocating computing resources to users in varying time zones. When an organization moves to cloud, it means moving away from traditional model Capex (buying dedicated hardware package and utilizing it over the period of time) to Opex (shared cloud on pay per use basis). Key benefits of cloud computing service are reduced the cost of technology infrastructure, streamlined processes and improved accessibility, reduced capital costs, improved flexibility, globalized workforce and many more.
