What Is Google App Engine?

What Is Google App Engine?

Google App Engine is a Platform as a Service (PaaS) offering that lets you build and run applications on Google’s infrastructure. App Engine applications are easy to build, easy to maintain, and easy to scale as your traffic and data storage needs change. With App Engine, there are no servers for you to maintain. You simply upload your application and it’s ready to go.

  App Engine Runtime Enviournment-

Google App Engine supports apps written in a variety of programming languages.

• Java: Using App Engine’s Java runtime environment, you can build your application using standard Java technologies.
• Python: App Engine features a fast Python interpreter and standard Python libraries.
• PHP: App Engine uses Google's Cloud Platform services under the hood when you call standard PHP functions.
• Go: App Engine features a Go runtime environment that runs natively compiled Go code.

Google App Engine makes it easy to build and deploy an application that runs reliably even under heavy load and with large amounts of data. It includes the following features:

• Persistent storage with queries, sorting, and transactions.
• Automatic scaling and load balancing.
• Asynchronous task queues for performing work outside the scope of a request.
• Scheduled tasks for triggering events at specified times or regular intervals.
• Integration with other Google cloud services and APIs.

Applications run in a secure, sandboxed environment, allowing App Engine to distribute requests across multiple servers, and scaling servers to meet traffic demands. Your application runs within its own secure, reliable environment that is independent of the hardware, operating system, or physical location of the server. For a full list of features.

 

App Engine Development Enviournment-

Software Development Kits (SDKs) for App Engine are available in all supported languages. Each SDK includes:

• All of the APIs and libraries available to App Engine.
• A simulated, secure sandbox environment, that emulates all of the App Engine services on your local computer.
• Deployment tools that allow you to upload your application to the cloud and manage different versions of your application.

The SDK manages your application locally, while the Administration Console manages your application in production. The Administration Console uses a web-based interface to create new applications, configure domain names, change which version of your application is live, examine access and error logs, and much more.

 

Quotas and limits-

App Engine gives you 1 GB of data storage and traffic for free, which can be increased by enabling paid applications. However, some features impose limits unrelated to quotas to protect the stability of the system. For more details on quotas, including how you can edit them to suit your needs, see the Quotas page.

To get started...

1. Download the SDK.
2. Sign up for an account.
3. Read the getting started information for your language.
4. Check out the rest of the App Engine documentation.
