Yes, Google App Engine (GCP’s App Engine) is designed to be highly scalable. It is a fully managed, serverless platform for developing and hosting web applications and APIs. One of the key features of App Engine is its ability to automatically scale resources to match the demands of your application.

App Engine automatically allocates resources to handle increasing traffic and scales down when the traffic subsides. This means you only pay for the resources you actually use, and you don’t have to worry about infrastructure management or provisioning.

App Engine supports popular programming languages, including Python, Java, Go, Node.js, PHP, Ruby, and .NET, and offers built-in services such as caching, databases, and logging. The platform also integrates with other Google Cloud services, making it easier to leverage various tools and components to build your application.

In summary, App Engine on Google Cloud Platform is highly scalable, enabling you to build applications that can effortlessly handle traffic fluctuations and growth.
