We map data flows to show understanding of system transactions, dependencies, fail over, compliance with regulations, change impacts, cloud migrations, firewall settings and capacity needs. Capturing, creating and maintaining data flow diagrams across many systems and applications in a large enterprise is not simple, as just mapping one system can be a challenge. In our webinar we cover Visio automation techniques to capture and refresh multiple sets of data flows, creating an institutional knowledge base lacking in many enterprises and service providers.
