“Cloud computing is the delivery of computing as a service rather than a product”“Cloud computing entrusts, typically centralized, services with your data, software, and computation on a published application programming interface (API) over a network.”“End users access cloud based applications through a web browser or a light weight desktop or mobile app while the business software and data are stored on servers at a remote location.”
• Infrastructure as a Service (IaaS)• Platform as a Service (PaaS)• Software as a Service (SaaS)
Infrastructure as a Service (IaaS)In this most basic cloud service model, cloud providers offer computers – as physical or more often as virtual machines –, raw (block) storage, firewalls, load balancers, and networks
Platform as a Service (PaaS)In the PaaS model, cloud providers deliver a computing platform and/or solution stack typically including operating system, programming language execution environment, database, and web server.Application developers can develop and run their software solutions on a cloud platform without the cost and complexity of buying and managing the underlying hardware and software layers
Software as a Service (SaaS)In this model, cloud providers install and operate application software in the cloud and cloud users access the software from cloud clients.The cloud users do not manage the cloud infrastructure and platform on which the application is running.
• Public cloud• Community cloud• Hybrid cloud• Private cloud
Public cloudApplications, storage, and other resources are made available to the general public by a service provider.Public cloud services may be free or offered on a pay-per-usage model.
Community cloudCommunity cloud shares infrastructure between several organizations from a specific community with common concerns (security, compliance, jurisdiction, etc.), whether managed internally or by a third- party and hosted internally or externally.
Hybrid cloudHybrid cloud is a composition of two or more clouds (private, community or public) that remain unique entities but are bound together, offering the benefits of multiple deployment models.
Private cloudPrivate cloud is cloud infrastructure operated solely for a single organization, whether managed internally or by a third-party and hosted internally or externally.
