![]() ![]() Your app receives web requests, performs work, and sends responses by interacting with this environment. Your Go application runs on Google’s scalable infrastructure and uses large-scale persistent storage and services.Īpp Engine builds and executes Go application code using a safe “sandboxed” environment. With the Google App Engine for Go, you can build web applications using the Go Programming Language. However, GAE now supports Google Cloud SQL a fully managed MySQL service hosted on Google Cloud Platform. This means that you can’t run MongoDB, for example, on the Google App Engine (GAE). DataStoreĪpp Engine Datastore is a schemaless object datastore providing robust, scalable storage for your web application. Putting data in the cloud improves the user experience because recovery is simplified and users have more access to their data. ![]() When developing such apps, it’s much safer to store data in a distributed manner and not solely on devices which could get lost, stolen, or destroyed. App Engine is also a popular backend system for mobile apps. While many applications running on Google App Engine are web-based apps, they are certainly not limited to those. The Developers Console supports all the Cloud Platform products, including App Engine, as well as other Google developer APIs. Google recommends that you use the Google Developers Console instead. Access the Console by visiting this link in your web browser. The Google App Engine Administration Console gives you complete access to the public version of your application. The list of all the services that are available to users changes quite often as new APIs are created. Need a database? Google provides both its traditional NoSQL scalable datastore and access to the relational MySQL-compatible Google Cloud SQL service. Want your app to send and receive e-mail or instant messages? That’s what the e-mail and XMPP APIs are for! Want to reach out to other web applications? Use the URLfetch service! Need Memcache? Google has a global Memcache API. The App Engine team has created a set of higher-level APIs/services for developers to use. These include: open a local file for writing, open a socket connection, and make operating system calls. This is a Warningīecause of the sandbox, applications can’t execute certain actions. To ensure this, all App Engine applications run in a restricted environment known as a sandbox. Sandboxĭevelopers would not be interested in letting other applications/users get any kind of access to their application code or data. And it is free to start: upload your app and share it with users right away, at no charge and with no commitment required. All applications can use up to 1 GB of storage and enough CPU and bandwidth to support an efficient app serving around 5 million page views a month, absolutely free.Ĭreating an App Engine application is easy, and only takes a few minutes. With App Engine, there are no servers to maintain: You just upload your application, and it is ready to serve your users. Google App Engine lets you run web applications on Google’s infrastructure. Furthermore, it provides a development platform… users get to create apps, not use the ones provided by the cloud vendor, and it leverages the infrastructure as a hosting platform. ![]() Instead of a fixed application (SaaS) or raw hardware (IaaS), App Engine manages your infrastructure for users. It is something in-between - PaaS (Platform-as-a-Service). Google App Engine is different from most other cloud systems because it is neither IaaS (Infrastructure-as-a-Service, e.g., Amazon EC2) nor SaaS (Software-as-a-Service, e.g., Salesforce). I’ll be able to change things, reorganize parts, and generally make a better eBook. As part of the lean publishing philosophy, you’ll be able to interact with me as the eBook is completed. Thanks for downloading and checking out this eBook. Constructive criticism is definitely appreciated I want this eBook to get better through your feedback. I can be reached via e-mail at Please contact me if you have any questions, comments, kudos or criticism on the eBook. Using Code ExamplesĪll of the code in this book can be used pretty much anywhere and anyhow you please. In the end, you will understand and know the how to deploy web apps to the Google App Engine. Don’t know how? If yes, then this eBook is for you and will show you how it’s done. Are you new to Go and taking part in the Go Challenge? Some of the challenges might require you to create a web app in Go and deploy it to the Google App Engine.
