Because of our Infrastructure Design service, I get a lot of questions about infrastructure requirements for Microsoft Dynamics CRM. Many times the customer is in the planning stages during these conversations and an overview of the infrastructure is appropriate. Below is a video I put together to give a general overview of Dynamics CRM infrastructure, how it can be scaled, and how high availability can come into play in the various components. Just a note that you might want to view it in full-screen mode in order to be able to see the diagrams more clearly. Enjoy!
