Platform-as-a-Service (PaaS) is a key enabler of software-driven innovation – facilitating rapid iteration and developer agility. It comprises a set of tools, libraries and services for deploying, managing and scaling applications in the cloud. Adopting an enterprise-grade, multi-cloud PaaS solution frees developers to create game-changing web and mobile applications. It also allows these applications to scale across cloud environments, based on the business need.
Like IaaS, PaaS includes infrastructure—servers, storage, and networking—but also middleware, development tools, business intelligence (BI) services, database management systems, and more. PaaS is designed to support the complete web application lifecycle: building, testing, deploying, managing, and updating.
PaaS allows you to avoid the expense and complexity of buying and managing software licenses, the underlying application infrastructure and middleware or the development tools and other resources
