What is Platform as a Service (PaaS)?

PaaS is a cloud platform that allows developers to quickly develop, run, and manage applications without the capital expense and maintenance requirements of an in-house infrastructure.

Platform as a service definition

Platform as a Service (PaaS) is a complete development environment that is hosted in the cloud and enables application developers to create apps quickly and easily. It usually includes an OS, web server, tools, programming language, database, network, servers, storage, and more. The PaaS provider hosts and maintains the system and often builds a solution tailored to the unique needs of the customer. The customer maintains control of its applications. Many providers offer pay-as-you-go and other online pricing models.

Why platform as a service?

PaaS allows businesses to quickly and confidently develop, deploy, and iterate applications and integrations without having to purchase and maintain supporting infrastructure. PaaS solutions usually scale automatically to meet demand, and speed processes through automation and standardization of development and deployment tasks. Multiple people can use the same development application concurrently, which allows several developers to work on a project and stakeholders to interact with the development team.

How is PaaS different from Iaas and SaaS?

PaaS builds on IaaS, which streamlines and automates the provisioning of compute resources. The “platform” layer is the operating system that allows developers to develop and deploy apps in a highly streamlined manner. SaaS offerings are cloud-based apps built for end users.
