The standard environment seems to fit your needs a lot more, though you will have to settle with using Node.js as you mentioned since Koa.js is not supported.
App Engine standard will provide you with a quicker instance startup time (seconds) compared to flex (minutes). It’s also ideal if your app requires rapid scaling to a few hundred requests per minute. Lastly, it’s intended to run at minimal cost when the app is not getting traffic, it can even scale to zero instances. For more information, I invite you to visit this page <https://cloud.google.com/appengine/docs/the-appengine-environments> which compares the two environments and their costs. I can understand how tricky it may be to decide between the two environments so please feel free to write back if you have any more inquiries. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
