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 PaaS offerings that handle provisioning, scaling, and health monitoring. OCI does not have a single, direct Beanstalk/App Service-style PaaS for general web apps; teams typically use OCI Compute instances or OCI Container Engine for Kubernetes (OKE) with supporting managed services (load balancer, monitoring) to achieve similar outcomes.
