What Is Cloud Computing?

Cloud computing refers to an on-demand access via the internet or other network, to IT resources such as servers, applications (physical and virtual), development tools such as data storage, networking capabilities and much more. They are hosted at remote data centers that are managed by a cloud services provider. Users are able to official statement access this infrastructure via secured connections. Cloud services are available on an ongoing basis or are charged according to use.

Companies that adopt cloud systems can cut down on the cost and time needed to maintain IT infrastructure, while also freeing IT staff to concentrate on more productive tasks. The savings that a business will experience will depend on the type of system they decide to migrate to the cloud and what they are replacing. However, a recent survey found that IT and business professionals reported saving between 30 to 50 percent by shifting to cloud computing.

There are a variety of cloud-based service models, such as Software as an Service(SaaS), Platform as a Serviceand Infrastructure as a Service. SaaS is the most familiar model and probably the one that the majority of companies already use. It delivers the application layer–software like CRM and office software, as well as email, over the internet, eliminating the requirement to maintain or upgrade hardware.

Another advantage is the ease with which companies can scale up or down the size of their servers and disk space, paying only for what they need when they need it. This elasticity that is rapid can be crucial to ensure that processes are agile and for rapid introduction of new technologies into production. Cloud providers can also keep IT departments current on the latest technological advancements without worrying about costly hardware.
