Software-defined wide-area network (SD-WAN) solutions transform an organization’s capabilities by leveraging the corporate wide-area network (WAN) as well as multi-cloud connectivity to deliver high-speed application performance at the edge of branch sites. One of the benefits of SD-WAN is that it provides a dynamic path selection among connectivity options: MPLS, 4G/5G and/or broadband, ensuring organizations can quickly and easily access business-critical cloud applications.
To provide connectivity to Microsoft Azure there are multiple scenarios available. They range from a very easy and IPSEC tunnel up to SDWAN scenarios integrating multiple connectivity options.
- Scenario 1: VPN Tunnel using IPSEC from the FortiGate edge devices to the Microsoft VPN gateway
- Scenario 2: VPN Tunnel using IPSEC from the FortiGate edge devices to a FortiGate deployed in Microsoft Azure
- Scenario 3: Connecting Azure ExpressRoute and VPN tunnel from the FortiGate edge device to Microsoft Azure
- Scenario 4: Encrypting the communication over Azure ExpressRoute using FortiGate at the edge and in Microsoft Azure
- Scenario 5: How to integrate with Microsoft Virtual WAN connectivity solution
