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.
All provide a managed way to deploy web apps without managing servers. App Engine is a Google Cloud PaaS with built-in scaling and traffic management. AWS Elastic Beanstalk and Azure App Service offer similar app deployment and scaling experiences. OCI does not have a direct, current one-to-one App Engine PaaS; teams commonly use OCI Container Instances or OCI Kubernetes Engine to run web apps with less server management than raw VMs.
