In the Clouds

Most likely you have at least heard about the ambiguous "cloud" and are familiar with a talent management system that claims to be "cloud-based." But what is the cloud all about, really? Read on for some basic definitions.

The cloud is a metaphor for the Internet in cloud computing.

Cloud computing enables a user to access software applications, hardware, data, and computer-processing power over the web, rather than by loading software onto an organization's server or a personal computer. Consequently, the user can use the power of the Internet (the cloud) as his personal computer, processor, and storage environment—connecting to tools and resources as needed.

A cloud-native system or application is designed from the ground up to work in the cloud. It is not an existing software or legacy system with a web front-end attached to it. Cloud-native systems must be inherently distributed to support operating in a cloud, and they are elastic—they should be able to scale applications down as well as up, based on load.

Additionally, a cloud-native system must offer multitenancy, which means that only a single instance of an application runs on a server, but it serves multiple client organizations or "tenants." Finally, these applications typically are self-service and offer granular billing (pay per use rather than pay by user or pay by timeframe).
