Using deployment diagrams to explain architecture and security to everybody (WHY2025)

This talk will enable you to lead architecture conversations and discuss their security options through an informal diagramming technique. I will use examples such as key/encryption architectures, DevOps, and even your home music system. Presentation at https://digitalinfrastructures.nl/why2025/ You have seen many diagrams of computer and information systems in your career. They have been around since the early days of computing. They can be useful, but there are a few typical problems with them: • They are drawn with obscure symbols that are only understood by architects • They are drawn in an inconsistent way • They are not used to their fullest potential. In my practice I have run into these problems often, and I have found ways to turn a certain type of diagram, a simplified version of deployment diagrams, into the cornerstone of explanation of what goes on in cloud and cybersecurity. In the talk I will lead you through the basic principles, and a few examples. This will enable you to lead architecture conversations and discuss their security options. I will use examples such as key/encryption architectures, DevOps, and even your home music system.
