Detailed explanation-1: -PaaS, or Platform-as-a-Service, is a cloud computing model that provides customers a complete cloud platform-hardware, software, and infrastructure-for developing, running, and managing applications without the cost, complexity, and inflexibility that often comes with building and maintaining that platform on-premises.

Detailed explanation-2: -PaaS, or platform as a service, is on-demand access to a complete, ready-to-use, cloud-hosted platform for developing, running, maintaining and managing applications.

Detailed explanation-3: -PaaS also reduces the complexity of building, testing, and deploying applications by keeping the developers inside of a well-defined environment that limits the ability for the developers to make mistakes.

Detailed explanation-4: -Some examples of IaaS services are DigitalOcean, AWS, Azure and Google Compute Engine. With PaaS, a provider offers more of the application stack than IaaS, adding OSes, middleware–such as databases–and other runtimes into the cloud environment. PaaS products include AWS Elastic Beanstalk and Google App Engine.

Detailed explanation-5: -PaaS provides a platform with tools to test, develop, and host applications in the same environment. Enables organizations to focus on development without having to worry about underlying infrastructure. Providers manage security, operating systems, server software and backups.
