La API de Backends se introdujo originalmente como una forma de proporcionar el procesamiento que no está orientado al usuario, con tiempos de espera más largos, tamaños de instancia diferentes, etcétera.
A partir de 2014, comenzamos a recomendar Módulos, que finalmente fueron renombrados como Servicios. Durante ese tiempo, agregamos instancias de backend (B_*) y controles de escalamiento para todos los Servicios, quitando así gran parte de la necesidad de una API de Backends separada.
El 13 de marzo de 2019, daremos de baja la API de Backends y todas las versiones existentes de backend. Ya no podrás implementar backends nuevos ni modificar los backends existentes, y estas versiones dejarán de entregar tráfico.
Migración
Consulta nuestras guías de migración para Python, Java y Go a fin de convertir tus backends en Servicios.
Si necesitas ejecutar el código durante más de 60 segundos, evalúa migrar a Cloud Tasks (tiempo de espera de 10 minutos), Kubernetes Engine o Compute Engine (tiempo indefinido).
