Cloud services basics

What are cloud services? Cloud services provide information technology capabilities as a service over the internet to multiple users at once. Many software vendors now deliver their services in the cloud as opposed to enterprises needing to host them onsite. Depending on the vendor's architecture, there is a varying degree of infrastructure that is outsourced to the cloud. 

  • Infrastructure as a Service (IaaS) is a provision model in which an organization outsources the equipment used to support operations, including storage, hardware, servers and networking components. The service provider owns the equipment and is responsible for housing, running and maintaining it. The customer typically pays on a per-use basis. (Examples: Rackspace, IBM, Amazon Web Services, Microsoft Azure)
  • Platform as a Service (PaaS) is a way to rent hardware, operating systems, storage and network capacity over the Internet. The service delivery model allows the customer to rent virtualized servers and associated services for running existing applications or developing new ones. (Examples: Amazon Web Services, Microsoft Azure)
  • Software as a Service (SaaS) is a software distribution model in which applications are hosted by a vendor or service provider and made available to customers over the Internet. (Examples: Google Apps, Microsoft 365, ServiceNow)
