Google Cloud's platform for building and hosting web applications without managing servers. Like renting a fully-managed restaurant kitchen where you just need to provide the recipes.
A developer uploads their Python web application to App Engine and Google handles all server management and scaling.
Google App Engine is a fully managed platform-as-a-service (PaaS) for deploying web apps without managing servers. AWS Elastic Beanstalk and Azure App Service are the closest managed PaaS equivalents. OCI does not have a single, direct App Engine-style PaaS; similar outcomes are typically built using OCI Compute or OCI Container Engine for Kubernetes (OKE) plus managed load balancing, autoscaling, and CI/CD.
