Back to Basics: SAP on AWS High Availability Setup with Overlay IP Address Routing
In this episode, Ratna discusses how to leverage AWS Overlay IP addressing and routing for high availability (HA) of your mission-critical SAP applications across multiple Availability Zones. She’ll explore a real-world scenario where a customer faced costly business disruptions due to outages impacting their primary and standby SAP databases hosted in the same data center location. See how Overlay IPs enable seamless failover of SAP HANA databases and SAP NetWeaver application clusters across AZs, preventing expensive downtimes. Discover the underlying architecture using AWS Transit Gateway, route tables, and Elastic Network Interfaces (ENIs).
You’ll get step-by-step guidance on implementing this highly available multi-AZ design:
✅ Overlay IP addressing outside your VPC CIDR range
✅ Route table configurations for intelligent IP traffic routing
✅ Cluster failover automation updating routing entries
✅ We also cover scenarios without AWS Transit Gateway, using Network Load Balancers to access Overlay IPs
Don’t let localized failures cripple your SAP landscape. Ensure business continuity and meet strict SLAs by utilizing AWS Overlay IP capabilities as a core HA strategy. Implement this multi-AZ architecture to keep your SAP workloads highly available and your operations running smoothly, even in the face of regional disruptions!
