The IaaS provider owns and maintains the equipment while the organization rents out the specific services it needs, usually on a "pay as you go" basis.
- Platform as a Service (PaaS) is a cloud model designed for software developers that streamlines the development process by shifting specific aspects of systems management to the service provider. PaaS is used to develop web and mobile applications using components that are pre-configured and maintained by the service provider, including programming languages, application servers and databases.
- Software as a Service (SaaS) is a cloud model that delivers on-demand applications that are hosted and managed by the service provider and typically paid for on a subscription basis. SaaS solutions offer a numberA unit of abstract mathematical system subject to the laws of arithmetic. of advantages over on-premises deployments, including minimal administration and maintenance, anywhere access, and in many cases improved communication and collaboration.
Organizations might implement all, two or only one of theses models. In all three of these cases, organizations take advantage of saving money and / or increasing efficiency (which makes more money).
