Computing as a service over the Internet (Cloud)

  • Cloud computing, often referred to as simply “the cloud,” is the delivery of on-demand computing resources—everything from applications to data centers—over the Internet on a pay-for-use basis.

Software as a Service (SaaS)

  • Cloud-based applications—or software as a service—run on distant computers “in the cloud” that are owned and operated by others and that connect to users’ computers via the Internet and, usually, a web browser

Platform as a Service (PaaS)

  • Platform as a service provides a cloud-based environment with everything required to support the complete lifecycle of building and delivering web-based (cloud) applications—without the cost and complexity of buying and managing the underlying hardware, software, provisioning and hosting.

Infrastructure as a Service (IaaS)

  • Infrastructure as a service provides companies with computing resources including servers, networking, storage and data center space on a pay-per-use basis.
