Checks from mindmap:

• VPN Gateway and Express Route DR Best Practices will apply to Hub & Spoke and VWan Architectures
• VPN Gateways
  • [x] Deploy Gateways in to multiple Availability Zones for resiliency: D4.9
  • [x] Redundancy in Azure is only half of the consideration - the on-prem side of the VPN needs to also be resilient.
• ExpressRoute
  • Each ExpressRoute Circuit contains two connections
  • [x] Having multiple ExpressRoute Circuits add additional redundant connection pairs: D4.14
  • [x] You can use VPN as a backup for ExpressRoute.
  • Routing for Multiple Circuits:
  • Be aware that you can leverage Connection Weights. You can leverage Connection Weights to ensure their is traffic symmetry.
  • Gateways:
    • [x] AZs: D4.6
• Data Gateway: not applicable
  • Leverage data gateway cluster to avoid single points of failure and to load balance traffic across gateways in a cluster
