Cloud computing eliminates the capital expense concerns of investing in more hardware and software. Cloud computing also eliminates several other resource burdens including setting up and running on-site datacenters, adding racks of servers, round-the-clock electricity bills, and hiring additional staff for sustaining on-premise infrastructure.
Most cloud computing services are provided on demand with self-service capabilities. This allows vast amounts of computing resources to be provisioned in minutes, typically with just a few mouse clicks, giving businesses flexibility and taking the pressure off capacity planning.
Cloud computing services include the ability to scale IT resources elastically. In "cloud-speak", that means increasing or decreasing computing power, storage, and bandwidth when it is needed, and from the desired geographic location.
On-site datacenters can require a lot of hardware set up, software patching, and other time-consuming IT management chores. Cloud computing removes the need for many of these tasks allowing IT teams to focus on activities that add value to the business.
The biggest cloud computing services run on a worldwide network of secure datacenters that are regularly upgraded to the latest generation of fast and efficient computing hardware. This offers several benefits over a single corporate datacenter, including reduced network latency for applications and greater economies of scale.
Cloud computing makes data backup and disaster recovery easier and less expensive because data can be mirrored at multiple redundant sites on the cloud provider's network. This ensures business continuity in the event of a catastrophic failure.
