Cloud computing has two meanings. The most common refers to running workloads remotely over the internet in a commercial provider’s data center, also known as the “public cloud” model. Popular public cloud offerings—such as Amazon Web Services (AWS), Salesforce’s CRM system, and Microsoft Azure—all exemplify this familiar notion of cloud computing. Today, most businesses take a multicloud approach, which simply means they use more than one public cloud service.

The second meaning of cloud computing describes how it works: a virtualized pool of resources, from raw compute power to application functionality, available on demand. When customers procure cloud services, the provider fulfills those requests using advanced automation rather than manual provisioning. The key advantage is agility: the ability to apply abstracted compute, storage, and network resources to workloads as needed and tap into an abundance of prebuilt services.


Cloud backup is a service in which the data and applications on a business’s servers are backed up and stored on a remote server. Businesses opt to back up to the cloud to keep files and data readily available in the event of a system failure, outage or natural disaster. Cloud backup for business operates by copying and storing your server’s files to a server in a different physical location. A business can back up some or all server files, depending on its preference.

Customers typically back up and restore their data and apps using a web browser or a service provider’s control panel. Cloud server backup is a necessity for many organizations today because they store most or all of their business-critical data and applications on cloud servers.

File backup and disaster recovery is the second leading use of cloud computing among medium and large enterprises, according to a recent Clutch survey. Sixty-two percent of the enterprise respondents use the cloud for this purpose, with only file storage (70 percent) being more popular.
