SQL Server normally relies on concurrency models in order to maintain the Isolation in ACID. As systems scale, this method can go from being a benefit to a hindrance, limiting the concurrency for our applications and hurting performance.   Throwing hardware at the problem can help, but does not address the fundamental issues. These can only be resolved with better database design and the correct configurations.   Join John as we work through the different design patterns that exist for increasing concurrency. From using specific data types, and partitioning, to how In-Memory OLTP can help. By the end of this season you will understand the different methods available to boost concurrency regardless of the size of your environment.
