Platform as a Service (PaaS) is a cloud computing model managed by a third-party provider that creates customized applications. PaaS uses the internet to deliver application infrastructure to users, presenting an easy and cost-effective service. Using PaaS makes application management more streamlined because it is scalable, customizable, and widely available. PaaS can also operate against data and processes inside a VPC, combining the simplicity of SaaS deployment with the security and privacy of the VPC.
Additionally, PaaS requires less coding and saves users from the need to install in-house hardware and software when developing new applications. Microsoft Azure App Services, OpenShift, Google App Engine, and AWS Elastic Beanstalk are all examples of PaaS.
