ID da região
O REGION_ID é um código abreviado que o Google atribui
com base na região que você selecionou ao criar o aplicativo. O código não
corresponde a um país ou estado, ainda que alguns IDs de região sejam semelhantes
aos códigos de país e estado geralmente usados. Para apps criados após
fevereiro de 2020, o REGION_ID.r está incluído nos
URLs do App Engine. Para apps existentes criados antes dessa data, o
ID da região é opcional no URL.
É possível usar vários métodos para se comunicar entre seus serviços do App Engine
ou com outros serviços, incluindo serviços do Google Cloud e
aplicativos externos.
A abordagem mais simples para a comunicação com o serviço do App Engine é
enviar solicitações HTTP segmentadas, em que o URL inclui o nome ou o ID de um
recurso. Por exemplo, inclua o ID de um serviço ou versão que
quer segmentar, além do ID do projeto do Google Cloud correspondente:
Para compartilhar dados entre bancos de dados e o aplicativo do App Engine ou outro
aplicativo externo, consulte
Noções básicas sobre armazenamento de dados e
arquivos.
No ambiente padrão, também é possível passar solicitações entre serviços e de
serviços para endpoints externos com a API
URL Fetch.
Além disso, os serviços no ambiente padrão que residem no mesmo projeto do Google Cloud também
podem usar uma das APIs do App Engine
