PaaS stands for Platform as a Service and provides an orchestration layer between front end applications and backend services. It allows for software deployment, application monitoring, topology provisioning, and SLA management. PaaS leverages IaaS resources and provides a standardized way to build, deploy, and manage applications independently of underlying infrastructure.
