What Is Cloud Computing?

Cloud computing refers to access on demand, via the internet for IT resources, including servers, applications (physical and virtual), development tools and networking capabilities, data storage and much more. They are hosted at remote data centers that are operated by a cloud services provider. This infrastructure is generally accessed by end users over secured connections. Cloud services are accessible via a subscription or by charging per use.

Companies that adopt cloud systems can cut down on costs and time needed to maintain IT infrastructure, while also freeing up IT staff to focus on other important tasks. The exact savings that a business experiences will depend on which systems it chooses to move to the cloud as well as what they’re replacing. A recent survey revealed that IT and business professionals reported savings of between 30 and 50 percent moving to the cloud.

A variety of cloud service models are available that include Software as a Service (SaaS), Platform as a Service and Infrastructure as a Service. SaaS is most likely the most popular, and is one that many companies use. It delivers the application-layer—software like CRM email, office software- over the internet, eliminating the need to upgrade or maintain hardware.

Another benefit is the ease with which companies can increase or decrease server size and disk space, paying only for the space they require as they require it. This elasticity that is rapid is crucial to ensure that work processes are agile and to speedily bring new technologies into production. Cloud providers can keep IT departments informed on the most recent technological advancements without worrying about costly hardware.
