Java 8 ha raggiunto la fine del supporto
e verrà
ritirato
il 31 gennaio 2026. Dopo il ritiro, non potrai eseguire il deployment di applicazioni Java 8, anche se la tua organizzazione ha utilizzato in precedenza un criterio dell'organizzazione per riattivare i deployment di runtime legacy. Le tue applicazioni Java 8 esistenti continueranno a essere eseguite e a ricevere traffico dopo la
data di ritiro. Ti consigliamo di
eseguire la migrazione all'ultima versione supportata di Java.
Documentazione dell'ambiente standard Java 8 di Google App Engine
L'ambiente standard di App Engine semplifica la creazione e il deployment di un'applicazione che
viene eseguita in modo affidabile anche se sottoposta a un carico elevato e con grandi quantità di dati.
L'applicazione viene eseguita all'interno del proprio ambiente sicuro, affidabile e indipendente dall'hardware, dal sistema operativo o dalla posizione fisica del server.
