Simply put, cloud computing is the delivery of computing services—which includes everything from servers, databases and storage to networking, software, intelligence and analytics—over the Internet (“the cloud”) offering resource flexibility, quicker innovation, and economies of scale. Typically, you only pay for the cloud services that you use which enables lower operating costs, increased infrastructure operational efficiency, and offers the ability to scale up or down as your business needs change.
Nearly everyone uses the cloud, but not everyone uses the same type of cloud. There are three different ways to deploy cloud resources: public, private and hybrid cloud. Each one offers similar benefits such as performance, reliability, scalability and cost-effectiveness, but the method you choose to deploy will be determined by your specific business needs.
Cloud computing has changed the way businesses think about IT resources; a massive shift from how resources were thought of and consumed less than 10 years ago. Some of the most common reasons organizations turn to cloud computing services include cost, global scalability, performance, productivity, reliability, speed, and security.
Removing the capital expense of running an onsite datacenter—think racks of servers, round-the-clock electricity (and potentially a backup generator) to power and cool said servers as well as the IT experts for managing the infrastructure as well as the outlay for purchasing and maintaining both hardware and software—the cost savings with cloud computing is undeniable.
The ability to scale elastically and deliver the perfect amount of IT resources, such as the allocation of more/less computing power, bandwidth, storage, the moment they’re needed and at the correct geographic location is one of the primary benefits of cloud computing.
The largest cloud computing providers leverage a global network of secure datacenters that are updated with the most up-to-date generation of fast and efficient computing hardware which allow for reduced network latency for applications and larger economies of scale than a single corporate datacenter.
On-site datacenters usually require a lot of time-consuming IT management tasks, such as hardware setup and constant software patching. With cloud computing, the provider maintains the datacenter and all of its components, freeing up IT teams to spend time on more pressing business needs.
Because data can be mirrored at multiple redundant sites on the cloud provider’s network, cloud computing makes data backup, disaster recovery, and business continuity easier and less expensive
The ability to provide computing services on demand and to utilize enormous amounts of computing resources at a moment’s notice and typically with only a few mouse clicks provides flexibility and takes the pressure of capacity planning out of their hands.
Most cloud providers have a expansive set of policies, technologies, and controls that strengthen an organization’s overall security posture and help to protect their data, apps, and infrastructure from potential threats.
