Platform as a service (PaaS) is a cloud computing model that provides a platform allowing customers to develop, run, and manage applications without dealing with the complexity of building and maintaining the underlying infrastructure. It supplies runtime environments, middleware, development tools, database services, and deployment automation.

Core features include application frameworks and programming languages support, automatic provisioning of compute resources, storage, and networking, built-in load balancing, auto-scaling, integrated CI/CD pipelines, monitoring, logging, and security services such as identity and access management. PaaS often offers managed databases, message queues, caching, and integration with external services.

Architecture emphasizes abstraction of the infrastructure and developer-centric tooling. It supports multi-tenant or isolated environments, and is accessible via web consoles and APIs. Deployment models include public cloud platforms, private PaaS deployments, or hybrid arrangements. Applications typically run in containers or managed runtimes, with vendor-provided runtimes and middleware.

Benefits include faster application development, lower operational burden, built-in scalability, easier collaboration, and predictable costs. Limitations include potential vendor lock-in, reduced control over infrastructure, performance variability, and dependence on platform capabilities. Use cases include web and mobile backends, APIs, microservices, event-driven workloads, and rapid prototyping.

Security and governance considerations involve data isolation, encryption at rest and in transit, IAM, auditing, and compliance with standards. Providers may offer compliance attestations, network controls, and data residency options. Notable examples include public cloud offerings such as Heroku, Google App Engine, AWS Elastic Beanstalk, and Microsoft Azure App Service, among others.
