The IaaS PaaS SaaS diagram shows a minor decrease in SaaS and a slight increase in IaaS and PaaS, which is expected to continue in the next few years. PaaS can be summarised as: A layer on top of IaaS, which provides the ability to run application software. In general, PaaS providers -- which include public cloud giants AWS, Microsoft and Google, but also a wide range of other players-- host application development platforms and tools on their own infrastructure, which enterprise development teams can then access as a service. PaaS definition. IaaS is attractive because acquiring computing resources to run applications or store data the traditional way requires time and capital. Cloud computing offers companies convenient models to access infrastructure, platform, and software offerings on a pay-as-you-go basis. It facilitates the use of software. definition of Cloud Computing comes from the National Institute of Standards and Technology (NIST) [1]. This helps businesses to eliminate the need for costly on-premises hardware and shift them to the cloud. It saves small and medium businesses from the expense of running their own data centers , and even large enterprises can use PaaS products to supplement on-site servers. Customers use the internet to access the hardware and resources. Cloud computing services are available through hyperscale public data centers, on-premises in privately owned data centers, or in hosted or managed settings. The debate over a cloud computing definition reflects its many elements and nuances. The NIST definition of cloud computing Author: NIST Computer Security Division (CSD) Keywords: NIST SP 800-145, The NIST Definition of Cloud Computing, Cloud Computing, SaaS, PaaS, IaaS, On-demand Self Service, Reserve Pooling, Rapid Elasticity, Measured Service, Software as a Service, Platform as a Service, Infrastructure as a Service Created Date IaaS stands for ‘Infrastructure as-a-Service’, PaaS stands for ‘Platform as-a-Service’, and SaaS stands for ‘Software as-a-Service’.
