📌 7 insights about Azure Hub & Spoke virtual networking: 1. A hub-and-spoke network topology is an efficient model for managing common communication or security requirements. 2. It allows centralized services that can be shared by multiple workloads, like network virtual appliances (NVAs) and DNS servers, saving on costs and management effort. 3. Peering workload virtual networks from different subscriptions to a central hub can overcome azure subscription limits for large azure environments. 4. This model allows for a separation of concerns: You can deploy individual workloads between central IT teams and workload teams. 5. The hub-and-spoke topology gives your IT department an effective way to enforce security policies in a central location, reducing the potential for misconfiguration and exposure. 6. The role of each spoke can be to host different types of workloads, providing a modular approach for repeatable deployments of the same workloads. 7. The hub deployment is bound to a specific Azure subscription, which has restrictions and limits. When limits might be an issue, you can scale up the architecture by extending the model to a cluster of hubs and spokes.
