Azure hub-spoke network architecture template

Quick answer

An Azure hub-spoke network puts shared connectivity and security services in a hub virtual network and isolates workloads in spoke virtual networks.

Cloudeval can help diagram, review, and explain this pattern from Azure project context.

What you can expect

A practical path from source input to diagram, report context, docs, exports, and the first AI question to ask.

Start here

Use this to

Understand and review an Azure hub-spoke network pattern with diagrams and evidence.

Best source to use

Confirm routing, DNS, firewall, gateway, and private endpoint relationships. Those details determine whether the hub-spoke design is accurate.

What you need

A hub-spoke design, ARM/Bicep output, or live Azure context.
Knowledge of the VNets, routes, firewalls, gateways, DNS, and private endpoints involved.
A Cloudeval project if you want reports or AI answers.

What you get

A component-level architecture explanation.
A diagram workflow for Azure hub-spoke review.
Review questions for exposure, routing, and evidence quality.

Fastest path to a useful result

1
Identify the hub VNet and spoke VNets.
2
Map firewall, gateway, route table, DNS, and private endpoint relationships.
3
Create or import the Azure project in Cloudeval.
4
Review the diagram and ask one question about exposure paths.

Decision guide

Check	Cloudeval path	Note
Hub	Shared ingress, egress, security, DNS, and monitoring.	Centralize shared controls.
Spokes	Workload VNets and subnets.	Keep workload boundaries clear.
Review focus	Routing, firewall, private endpoints, and exposure.	Missing relationships should be investigated.
Output	Diagram, reports, and AI questions.	Use exports for stakeholder review.

Who this is for

Azure network architects
Platform teams
Security reviewers
Consultants building review material

How it works

1
Define the hub virtual network for shared ingress, egress, and security services.
2
Place workload virtual networks in spokes with clear routing and segmentation boundaries.
3
Represent firewalls, gateways, route tables, private endpoints, DNS, and monitoring resources where used.
4
Create or import the Azure project in Cloudeval using ARM/Bicep output or live Azure sync.
5
Review the architecture diagram and dependency view for missing or unexpected connections.
6
Run reports and ask questions about exposure paths, stale context, and evidence quality.

Hub-spoke architecture components

Start with the hub virtual network, workload spoke virtual networks, and subnets.

Add Azure Firewall or a network virtual appliance, VPN or ExpressRoute gateway, route tables, private DNS, private endpoints, monitoring, and identity controls.
Cloudeval should explain the components in text so reviewers can understand the network without opening the editor.

Terminal and agent workflow

Use the CLI to create a project from an ARM template when the architecture is described as IaC.
Use Cloudeval chat or MCP-enabled agents to ask which paths are exposed and which report findings support the answer.
Export diagrams from the CLI or app when the template needs to become review material.

How to trust the result

Check route tables, peering, DNS, and gateway paths before treating the diagram as accurate.
Keep workload spokes isolated unless a shared service truly needs access.
Use private endpoints and firewall rules as review items, not decorations.

FAQ

What is the purpose of an Azure hub-spoke architecture?

It centralizes shared services such as connectivity, security inspection, DNS, and monitoring while keeping workloads isolated in separate spokes.

Can Cloudeval review a hub-spoke architecture?

Yes, when the architecture is represented in a Cloudeval Azure project with enough resource, graph, and report context.

Can this template become a public diagram?

Only after a sanitization flow removes resource names, IDs, IPs, account metadata, screenshots, and sensitive findings.

How do I generate an Azure architecture diagram automatically?How can I chat with my Azure architecture?How do I export cloud diagrams from the CLI?

Build this workflow in Cloudeval

Start with a Cloudeval Azure project, then connect diagrams, reports, source links, CLI automation, and MCP-compatible agent workflows around the same source of truth.
