Concepts
When designing ExpressRoute for your SAP workloads, consider the following factors:
- Bandwidth requirements: Evaluate the bandwidth requirements for your SAP workloads, considering factors like data transfer, user load, and potential peak usage. Azure ExpressRoute offers different bandwidth options, ranging from 50 Mbps to 10 Gbps.
- Redundancy and high availability: To ensure business continuity, it is crucial to design a redundant and highly available ExpressRoute connectivity. Consider establishing redundant connections to Azure, leveraging ExpressRoute Global Reach for connecting multiple Azure regions, and using ExpressRoute FastPath for high-performance connectivity.
- Network topology: Plan the network topology that best suits your SAP workloads. You can choose between the “Private Peering” option, which extends your private networks into Azure, or the “Microsoft Peering” option, which enables connectivity to Azure platform services.
Configuring Azure ExpressRoute for SAP Workloads
Once you have designed the ExpressRoute connectivity for your SAP workloads, follow these steps to configure it:
- Provision an ExpressRoute circuit: Start by provisioning an ExpressRoute circuit using the Azure portal, Azure CLI, or Azure PowerShell. Specify the bandwidth and connectivity type (Ethernet or IP) based on your requirements.
- Configure the peering connections: After provisioning the circuit, configure the peering connections. For SAP workloads, you need to establish both private peering and Microsoft peering.
- Private Peering: Create a private peering connection to extend your on-premises networks to Azure. Specify the BGP (Border Gateway Protocol) settings, IP addresses, and routing preferences.
- Microsoft Peering: Configure a Microsoft peering connection to enable connectivity to Azure platform services. This will allow your SAP workloads to communicate with Azure services like Azure SQL Database or Azure Storage securely.
- Implement route filters: To control the routing of traffic between your networks and Azure, implement route filters. You can use Azure route filters to define the path for inbound and outbound traffic, ensuring optimal performance and security.
- Enable ExpressRoute Direct: If you require high-performance connectivity, consider enabling ExpressRoute Direct. This allows you to bypass the network virtualization layer and connect directly to the Azure backbone, minimizing network latency.
- Monitor and optimize performance: Continuously monitor the performance of your ExpressRoute circuit using Azure Monitor. Leverage tools like Azure Network Performance Monitor to identify and resolve any connectivity or performance issues.
Conclusion
Designing and configuring Azure ExpressRoute for hybrid connectivity with SAP workloads is critical to ensure a seamless integration of your on-premises networks with Azure. By considering factors like bandwidth requirements, redundancy, and network topology, you can design a robust ExpressRoute infrastructure. Following the steps to provision ExpressRoute circuits, configure peering connections, and implement route filters will enable you to establish a secure and performant connectivity for your SAP workloads in Azure.

Great post on configuring Azure ExpressRoute for hybrid connectivity! It really helped me understand the basics.
Can anyone explain the benefits of using ExpressRoute over a traditional VPN for SAP workloads?
I followed the steps mentioned and successfully set up ExpressRoute, but I’m facing issues with routing. Any suggestions?
Wonderful read. This was very insightful!
In my opinion, the process is over-complicated. There should be simpler ways to set this up.
Do I need to have an existing VPN before setting up ExpressRoute?
How do I ensure high availability for SAP workloads using ExpressRoute?
Well-articulated. Appreciate the effort behind this!
