We are using Azure Active Directory for registering client applications. The client applications use the AAD clientId and secret to get an access token to authenticate to the back end microservices we have in place in Azure.
We have these microservices sitting behind an Azure Traffic Manager. My question is, what will happen to the OAuth 2.0 token if the following scenario occurs:
- A User is authenticated and is using backend microservice 1 (instance 1)
- The user is switched by the traffic manager to backend microservice 1 (instance 2)
Will they need to re-logon?
