It’s often not practical in a real-world cloud app to avoid storing some form of state for a user session, but some approaches impact performance and scalability more than others. If you have to store state, the best solution is to keep the amount of state small and store it in cookies. If that isn’t feasible, the next best solution is to use session state with a provider for distributed, in-memory cache.
Azure Cache for Redis provides a session state provider that you can use to store your session state in-memory with Azure Cache for Redis instead of a SQL Server database.
