Platform as a service
Platform as a service (PaaS) is a cloud service model that provides a managed application development, deployment, or runtime platform while abstracting management of the underlying infrastructure.
Acing the CCNA Exam: Volume 2 Advanced Networking and Security
Platform as a service is a cloud service model that provides an application development and execution platform while the customer manages the applications.
- How it is used
- Provides customers with a managed platform for developing, running, and managing applications without maintaining application infrastructure.
- How deep it goes
- Defines the responsibility boundary and distinguishes PaaS from SaaS and IaaS, but does not detail platform configuration or implementation.
- Examples
- Uses a responsibility-spectrum figure comparing PaaS with SaaS, IaaS, colocation, and on-premises solutions.
- What you can do after
- Evaluate cloud service choices by identifying which party manages the applications, platform, and infrastructure.

Platform as a Service is a cloud service model that provides a managed application platform while abstracting underlying infrastructure.
- How it is used
- Positions PaaS as a way to deploy an application quickly without first managing servers.
- How deep it goes
- Works through health checks, App Engine configuration, and a deployment pipeline; leaves underlying server provisioning abstracted.
- Examples
- Uses a Go health handler, App Engine YAML, and a GitHub Actions deployment followed by an HTTP request.
- What you can do after
- Apply it via Google App Engine by configuring health checks and a test-gated deployment pipeline.
Microsoft Azure in Action
Platform as a service (PaaS) is a cloud service model that provides a managed application platform so customers can deploy software without managing the underlying infrastructure and operating system.
- How it is used
- Deploys applications while abstracting operating-system maintenance and much infrastructure work.
- How deep it goes
- Explains abstraction and shared security responsibilities, then compares scaling, startup time, and control with serverless.
- Examples
- Uses Azure web services, hybrid virtual-network access, Entra ID, and serverless services as comparison points.
- What you can do after
- Evaluate PaaS against IaaS and serverless using responsibility, scaling, startup, and control trade-offs.

Amazon Web Services in Action, Third Edition: An in-depth guide to AWS
A platform as a service is a cloud service model that provides a managed platform for deploying and running applications without managing the underlying infrastructure.
- How it is used
- Frames PaaS as a managed way to deploy custom cloud applications while contrasting it with infrastructure and software service models.
- How deep it goes
- Defines the service model and works through App Runner deployment, operations, pricing, and limitations without detailing platform internals.
- Examples
- Uses AWS App Runner to launch, inspect, price, and delete a containerized web server.
- What you can do after
- Operate a containerized web application through AWS App Runner using creation, status, URL, and deletion commands.
