Traffic Manager to Load balance Layer 4 traffic between On Prem Physical machines and Azure VM

Question

Can Traffic Manager be used to load Balance(Active-Active or Active-Passive) Non-HTTP(S) Layer 4 traffic between On Premises and Azure Virtual Machines.

Answer 1

Traffic Manager performs DNS-based load balancing which can be configured to distribute traffic across endpoints, assuming your on-premises machines are exposed to the internet.

If not, you should instead use Azure Load Balancer with your on-premises network connected to your Azure VNET.

Answer 2

There are three types of endpoint supported by Traffic Manager:

• Azure endpoints are used for services hosted in Azure.
• External endpoints are used for IPv4/IPv6 addresses, FQDNs, or for services hosted outside Azure. Theses services can either be on-premises or with a different hosting provider.
• Nested endpoints are used to combine Traffic Manager profiles to create more flexible traffic-routing schemes to support the needs of larger, more complex deployments.

With priority traffic-routing method, you can set an Active-Active or Active-Passive setup.
