Google Cloud App Engine
Google Cloud’s App Engine (GAE) is an HTTP-based platform-as-a-service (PaaS) cloud computing platform for hosting web applications, REST APIs, and mobile backends. You can develop applications using multiple languages, including Python, C#, Java, Node.js, PHP, Ruby, Go, and .NET, or any other language using custom runtimes. Applications are sandboxed and run across multiple Google-managed servers. GAE supports automatic scaling for web applications, allocating more resources to web applications as the amount of requests increases.
With App Engine, you pay only for the resources your applications consume. The service provides a free tier, and scaling is handled automatically based on the traffic your application receives (see: Google Cloud’s App Engine (GAE) is an HTTP-based platform-as-a-service (PaaS) cloud computing platform for hosting web applications, REST APIs, and mobile backends.

With App Engine, you pay only for the resources your applications consume. The service provides a free tier, and scaling is handled automatically based on the traffic your application receives (see: Pricing | App Engine | Google Cloud for pricing information). Since App Engine is a managed service, Google automatically updates and patches the underlying OS and language runtimes. Additionally, App Engine ensures security by adhering to compliance standards like ISO, SOC, and PCI.
Many users leverage App Engine in conjunction with GCP’s DevOps capabilities, such as continuous deployment through Cloud Build, GitHub, or other CI/CD tools, built-in monitoring with Cloud Logging and Cloud Monitoring, and versioning capabilities for deployment and rollback.
