Crea una aplicación de Go 1.11 en el entorno estándar de App Engine
ID de región
REGION_ID es un código abreviado que Google asigna en función de la región que eliges cuando creas la app. El código no corresponde a un país ni a una provincia, aunque algunos ID de región puedan parecer similares a los códigos de país y provincia que se suelen usar. En el caso de las apps creadas después de febrero de 2020, REGION_ID.r se incluye en las URL de App Engine. En el caso de las apps existentes creadas antes de esta fecha, el ID de región es opcional en la URL.
En esta página, se muestra cómo implementar una aplicación básica de App Engine que muestra un mensaje corto. Si quieres ver una introducción más detallada de Go en App Engine, consulta Compila una app.
No hay costos asociados por usar esta guía. Ejecutar esta app de muestra por sí sola no supera tu cuota gratuita.

Ubicaciones de App Engine
App Engine es regional, lo que significa que la infraestructura que ejecuta las apps se encuentra en una región específica, y Google la administra para que esté disponible de forma redundante en todas las zonas dentro de esa región.
El cumplimiento de tus requisitos de latencia, disponibilidad o durabilidad debe ser un factor principal para seleccionar la región en la que se ejecutan las apps. Por lo general, puedes seleccionar la región más cercana a la de los usuarios de la app, pero debes considerar las ubicaciones en las que App Engine está disponible y las ubicaciones de los otros productos y servicios de Google Cloud que usa la app. Usar servicios en varias ubicaciones puede afectar la latencia de la app y sus precios.
No puedes cambiar la región de una app una vez configurada.
Si ya creaste una aplicación de App Engine, puedes ver su región mediante una de las siguientes opciones:

Initialize your App Engine app with your project and choose its region:\n\n gcloud app create --project=[YOUR_PROJECT_ID]\n\n When prompted, select the [region](/appengine/docs/legacy/standard/go111/locations)\n where you want to locate your App Engine application.\n | **Caution**: You cannot change an app's region once it has been set.\n2. Install the following prerequisites:\n\n - [Download\n and install Git](https://git-scm.com/).\n\n \u003cbr /\u003e\n\n \u003cbr /\u003e\n\n3. \n - Run the following command to install the\n [gcloud component](/sdk/docs/managing-components) that includes the\n App Engine extension for Go 1.11:\n\n gcloud components install app-engine-go\n\n### App Engine locations\n\n\u003cbr /\u003e\n\nApp Engine is *regional* , which means the infrastructure that runs your apps is\nlocated in a specific region, and Google manages it so that it is available\nredundantly across\n[all of the zones within that region](/docs/geography-and-regions).\n\nMeeting your latency, availability, or durability requirements are primary\nfactors for selecting the region where your apps are run. You can generally\nselect the region nearest to your app's users, but you should consider [the\nlocations where App Engine is available](/about/locations#region)\nas well as the [locations](/about/locations#region) of the other\nGoogle Cloud products and services that your app uses. Using services\nacross multiple locations can affect your app's latency as well as its\n[pricing](/appengine/pricing).\n\nYou cannot change an app's region after you set it.\n| **Note:** Two locations, which are called `europe-west` and `us-central` in App Engine commands and in the Google Cloud console, are called `europe-west1` and `us-central1`, respectively, elsewhere in Google documentation.\n\nIf you already created an App Engine application, you can view its\nregion by doing one of the following:\n\n- Run the `gcloud app describe` command.\n\n- Open the\n [App Engine Dashboard in the Google Cloud console](https://console.cloud.google.com/appengine).\n The region appears near the top of the page.\n\nOK\n\nThis quickstart assumes that you are familiar with the Go programming language\nand that you have [installed Go](https://golang.org/doc/install).\n\nDownload the Hello World app\n----------------------------\n\nWe've created a simple Hello World app for Go so you can quickly get a feel for\ndeploying an app to Google Cloud Platform. Follow these steps to download Hello\nWorld to your local machine.\n\nDownload the sample app and navigate into the app directory:\n\n1. Clone the [Hello World sample app repository](https://github.com/GoogleCloudPlatform/golang-samples.git):\n\n git clone https://github.com/GoogleCloudPlatform/golang-samples\n\n Alternatively, [download](https://github.com/GoogleCloudPlatform/golang-samples/archive/master.zip)\n the sample as a zip file and extract it.\n2. Change to the directory that contains the sample code:\n\n cd golang-samples/appengine/go11x/helloworld/\n\nDeploying Hello World to App Engine\n-----------------------------------\n\n1. Deploy the Hello World app on App Engine by running the following\n command from the `golang-samples/appengine/go11x/helloworld` directory:\n\n gcloud app deploy\n\n2. View the live app at\n `https://`\u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e`.`\u003cvar translate=\"no\"\u003e\u003ca href=\"#appengine-urls\" style=\"border-bottom: 1px dotted #999\" class=\"devsite-dialog-button\" data-modal-dialog-id=\"regional_url\" track-type=\"progressiveHelp\" track-name=\"modalHelp\" track-metadata-goal=\"regionalURL\"\u003eREGION_ID\u003c/a\u003e\u003c/var\u003e`.r.appspot.com`:\n\n gcloud app browse\n\nThe message **Hello, World!** is now delivered by a web server running on\nan App Engine instance.\n\n**Congratulations!** You've successfully deployed a Go web service on\nApp Engine!\n\nClean up\n--------\n\nIf you want to continue learning about App Engine, you can keep\nyour Google Cloud project and follow along with\n[Building an App](/appengine/docs/legacy/standard/go111/building-app).\n\nAlternatively, you can delete your Google Cloud project to stop billing\nfor all the resources used within that project.\n\n| **Caution** : Deleting a project has the following effects:\n|\n| - **Everything in the project is deleted.** If you used an existing project for the tasks in this document, when you delete it, you also delete any other work you've done in the project.\n| - **Custom project IDs are lost.** When you created this project, you might have created a custom project ID that you want to use in the future. To preserve the URLs that use the project ID, such as an `appspot.com` URL, delete selected resources inside the project instead of deleting the whole project.\n|\n|\n| If you plan to explore multiple architectures, tutorials, or quickstarts, reusing projects\n| can help you avoid exceeding project quota limits.\n1. In the Google Cloud console, go to the **Manage resources** page.\n\n [Go to Manage resources](https://console.cloud.google.com/iam-admin/projects)\n2. In the project list, select the project that you want to delete, and then click **Delete**.\n3. In the dialog, type the project ID, and then click **Shut down** to delete the project.\n\n\u003cbr /\u003e\n\nWhat's next\n-----------\n\nNow that you have experience deploying a web service on App Engine,\nget a more in-depth introduction to Go on App Engine by reading\n[Building an App](/appengine/docs/legacy/standard/go111/building-app)."]]
