Backend processing (billing pipelines and data analysis)Įach service in GAE consists of the source code from our app and the corresponding App Engine configuration files.Internal or administration-type requests.Therefore, we can run our app in a single service or we can deploy multiple services to run as a microservice-set.Įx: An app which handles customer requests may include distinct services, each handle different tasks, such as: Generally, App Engine services behave like microservices. Services used in GAE is to constitute our large apps into logical components that can securely share the features of App Engine and communicate with each other. In this diagram, the app has 2 services that contain different versions, and two of those versions are actively running on different instances: The following diagram shows the hierarchy of a GAE application running with two services. When you create App Engine application, all your resources are created in the user defined region, including app code and collection of settings, credentials and your app's metadata.Įach GAE application includes at least one service, the default service, which can hold many versions, depends on your app's billing status. The Application part of GAE is a top-level container that includes the service, version and instance-resources that make up the app. Performance : Users can use a wider CPU and memory setting.Īpp Engine is created under Google Cloud Platform project when an application resource is created.Native feature support : Features such as microservices, authorization, databases, traffic-splitting, logging, etc are supported.Infrastructure Customization : GAE flexible environment instances are Compute Engine VMs, which implies that users can take benefits of custom libraries, use SSH for debugging and deploy their own Docker Containers.Integration with other GCP services and APIs.Ģ) Flexible Environment where developers have more flexibility such as running custom runtimes using Docker, longer request & response timeout, ability to install custom dependencies/software and SSH into the virtual machine.Scheduled tasks for triggering events at regular or specific time intervals. ![]() Asynchronous task queues for performing work.Persistent storage with queries, sorting, and transactions.Also known as split testing or bucket testing, it is used to compare two versions of a webapp against each other to determine which one performs better.) and see which version performs better under various workloads.ġ) Standard Environment with constrained environments and support for languages such as Python, Go, node.js It is a randomized experiment with two variantsA and B. Users can route traffic to different app versions to A/B testing (It is a research methodology applicable in determining user experience. Another way to use GAE is for Application Testing. One way to use GAE is building scalable application back ends that adapt to workloads as needed. They can use this to test and deploy code in the cloud. Users can create an account under GAE section, set up an SDK and write an application source code. Google App Engine also removed system admin and manual tasks to make it easier to write scalable apps. The legacy applications which are usually non-compatible to Google App Engine, must be rewritten with regards to Google App Engine to meet the standard requirements because not all the applications are supported by GAE. Applications in the Google App Engine require the use of Google query language and store data in Google Bigtable.Īpplications must comply with GAE standards. These applications are required to be written in, namely: Java, Python, PHP, Go, Node.JS. It enables developers to take full advantage of its serverless platform. Google App Engine is a cloud computing Platform as a Service (PaaS) which provides Web app developers and businesses with access to Google’s scalable hosting in Google managed data centers and tier 1 Internet service. ![]()
