The lesson
Compare your approach with the old way as two diagrams side by side, each with a short list of points below.
The headline is "Verkada's cloud-first approach to access control". Two cards sit side by side: "TRADITIONAL SYSTEMS" shows door controllers, a master controller, firewalls, access servers and SQL databases, and remote clients with "ancient software", while "HYBRID-CLOUD ACCESS CONTROL" shows a door controller, a cloud, and your devices. Under them sit five bold-labelled problems and six benefits.
Don't copy the mocking labels, such as "ancient software", unless you can back them up. Keep the side-by-side diagram format.
