Azure Networking Design and Architectures

Primary LanguageShell

Azure Networking: The Art of The Possible and the why

The purpose of this repo is to deliver layered, reusable and github friendly network architecture diagrams for Cloud Solutions Architects to run effective Azure design and skilling sessions. The content is based on real customer and partner design sessions with collaboration from cross-functional architects. The repository will include tips and tools for effective story telling that explain the why behind the design options based on requirements and the art of the possible. The design areas include - Azure Networking, Hybrid connectivity architectures, routing, firewalling, load balancing, multi-region, secure design, cross functional networking areas and AKS networking. The networking complexity is broken down into layers with one diagram per design area using draw.io now diagrams.net. This repo will include configuration snippets to reduce the lab prep time and the need to leave the labs running for demos.
