A managed platform service that runs your web applications without requiring you to set up or manage the underlying servers. Like renting a fully-furnished apartment instead of building a house — you just move in your code and everything else is handled for you.
A development team uses AWS Elastic Beanstalk to deploy their Node.js web application. They upload their code and Beanstalk automatically handles capacity provisioning, load balancing, auto-scaling, and health monitoring — letting them focus on features instead of infrastructure.
These services provide a managed platform to deploy web apps without managing servers. Elastic Beanstalk, Azure App Service, and App Engine are direct PaaS-style web app hosting options. OCI does not have a single, direct “App Service/App Engine” equivalent; teams typically use Functions + API Gateway for serverless web backends or run web apps on managed containers (OKE/Container Instances) with less “one-click” web app PaaS abstraction.
