Java 8 telah mencapai akhir dukungan
dan akan dihentikan penggunaannya
pada 31 Januari 2026. Setelah penghentian penggunaan, Anda tidak akan dapat men-deploy aplikasi Java 8, meskipun organisasi Anda sebelumnya menggunakan kebijakan organisasi untuk mengaktifkan kembali deployment runtime lama. Aplikasi Java 8 yang ada akan terus berjalan dan menerima traffic setelah
tanggal penghentiannya. Sebaiknya Anda bermigrasi ke versi Java terbaru yang didukung.

ID region
REGION_ID adalah kode singkat yang ditetapkan Google berdasarkan region yang Anda pilih saat membuat aplikasi. Kode ini tidak sesuai dengan negara atau provinsi, meskipun beberapa ID region mungkin tampak mirip dengan kode negara dan provinsi yang umum digunakan. Untuk aplikasi yang dibuat setelah Februari 2020, REGION_ID.r disertakan dalam URL App Engine. Untuk aplikasi lama yang dibuat sebelum tanggal tersebut, ID region bersifat opsional dalam URL.
Anda dapat menggunakan berbagai metode untuk berkomunikasi di antara layanan App Engine Anda atau dengan layanan lain, termasuk layanan Google Cloud dan aplikasi eksternal.
Pendekatan paling simpel untuk berkomunikasi dengan layanan App Engine Anda adalah dengan mengirim permintaan HTTP yang ditargetkan, dengan URL yang menyertakan nama atau ID resource. Misalnya, Anda dapat menyertakan ID layanan atau versi yang ingin ditargetkan, selain project ID Google Cloud yang sesuai:
Untuk berbagi data di seluruh database dan aplikasi App Engine Anda atau beberapa aplikasi
eksternal lainnya, lihat
Memahami Penyimpanan Data dan
Penyimpanan File.
Dalam lingkungan standar, Anda juga dapat meneruskan permintaan antara layanan dan
dari layanan ke endpoint eksternal menggunakan
URL Fetch API.
Selain itu, layanan di lingkungan standar yang berada dalam projectGoogle Cloud yang sama juga dapat menggunakan salah satu API App Engine untuk tugas berikut:
