Hub-and-spoke topologies
On This Lesson 4 topics
This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.
In this lesson
structure many networks with a central hub.
Planned topics
- Spokes are workload networks; the hub holds shared services: egress, firewalls, hybrid links, DNS.
- Spokes connect to the hub, not to each other, so traffic is inspected and controlled in one place.
- Connection options: peering (simple, non-transitive) or a transit gateway-style service (scalable, extra cost); verify before recording.
- Central hybrid link means one connection serves all spokes.
- The hub is critical: design it for resilience and keep it small.
Draft outline details
Demonstration
a star diagram: hub in the middle with the VPN to the data center; prod, non-prod, and shared-services spokes around it.
Check your understanding
Why avoid spoke-to-spoke links?
Show answer
They bypass central inspection and create a tangled mesh.
