What is this?

Enterprise networking uses hub-spoke, shared services, DNS, and hybrid connectivity at scale.

Why should you care?

CloudVerse landing zones put shared firewalls/DNS in a hub; apps live in spokes.

See it live — copy this example

Use AWS/Azure/GCP free tier or local Docker/Kind. Sketches and YAML are meant to be typed and adapted.

# hub-spoke
# Hub: VPN/firewall/DNS
# Spoke-prod ↔ Hub ↔ Spoke-nonprod (no direct spoke-spoke by default)

What happened?

Centralize egress inspection when required.
Avoid transitive routing surprises.
Document CIDR inventory.

Practice next

Draw hub-spoke.
Place shared DNS in hub.
Block spoke-to-spoke by default.
Add inspection VPC pattern.
Register all CIDRs in a sheet.

Remember

Hub shared services. Spokes for apps. CIDR inventory.

CloudVerse hub-spoke

Prod/nonprod spokes via hub.

Outcome: Shared DNS/VPN without mesh chaos.
