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. Most companies with private clouds will evolve to manage workloads across data centers.Metered service so you only pay for what you use.
Infrastructure as a service provides companies with computing resources including servers, networking, storage, and data center space on a pay-per-use basis.
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 provides a cloud-based environment with everything required to support the complete lifecycle of building and delivering.
Public clouds are owned and operated by companies that offer rapid access over a public network to affordable computing resources. With public cloud services, users don’t need to purchase hardware, software, or supporting infrastructure, which is owned and managed by providers.
A private cloud is infrastructure operated solely for a single organization, whether managed internally or by a third party, and hosted either internally or externally. Private clouds can take advantage of cloud’s efficiencies, while providing more control of resources and steering clear of multi-tenancy.
A hybrid cloud uses a private cloud foundation combined with the strategic integration and use of public cloud services. The reality is a private cloud can’t exist in isolation from the rest of a company’s IT resources and the public cloud.
