Will the token endpoint be able to service simultaneous token requests? Currently, we have has two instances, which will be reconfigured to obtain a new token every 30 minutes. In the future, we could have to scale to 10 instances. What happens if all 10 attempts to obtain a token at once?
Yes, the token endpoint can service token requests simultaneously. You can access the token at once and there won’t be any impact. As you can imagine there are thousands of request hits about auth server every second and it processes the data. So there won’t be any impact if there are simultaneous requests on the auth token.
