What Is Cloud Computing?

Cloud computing is the term used to refer to on-demand internet access to IT resources, which includes applications, servers (physical or virtual) tools for development and storage of data. These IT resources are located in a remote datacenter, which is managed by cloud services providers. The cloud computing infrastructure is typically accessed by users via a secure connection. Cloud services can be accessed through a subscription or charging per usage.

Businesses that make use of cloud systems can cut down on costs and time required to maintain IT infrastructure, while also allowing IT personnel to concentrate on other productive tasks. The savings a business will realize will depend on the systems they decide to transfer to the cloud, as well as what they are replacing. However, a recent study found that IT and Business professionals reported saving between 30 to 50 percent by moving to the cloud.

There are several cloud service models, including Software as a Service(SaaS), Platform as a Serviceand Infrastructure as a Service. SaaS is the most familiar model and probably the one that most businesses are already using. It provides the application layer, which includes software such as CRM Office, email and CRM software–over the internet, thus eliminating the requirement to maintain or upgrade hardware.

Businesses also gain from the ease of scaling up or down the size of their servers as well as disk storage, only paying for what they require. This elasticity that is rapid is an important feature for efficient work processes and for quickly getting new technologies into production. Cloud providers can keep IT departments informed on the latest technological advancements without the need to worry about expensive hardware.
