Hybrid Architecture Design Patterns for ERP
Three proven hybrid patterns address different ERP deployment requirements. The split-tier pattern places the ERP database and application server in the cloud while keeping shop floor integration servers on-premise. The burst pattern runs normal workloads on-premise but bursts MRP, financial close, and reporting workloads to the cloud during peak periods.
The edge-cloud pattern uses Azure Arc or AWS Outposts to extend cloud management to on-premise infrastructure while maintaining local data processing.
- Split-tier pattern: ERP application and database in Azure/AWS, MES and SCADA integration servers on-premise, connected via ExpressRoute or Direct Connect with <20ms latency
- Burst pattern: on-premise ERP for daily operations, cloud instances for MRP runs, month-end close processing, and ad-hoc reporting, saving 40-60% versus permanently provisioned cloud resources
- Edge-cloud pattern: Azure Arc-enabled servers on-premise managed through Azure Portal, or AWS Outposts rack for consistent AWS APIs on-premise with local data residency
- Data residency pattern: financial and HR data in a region-specific cloud instance (e.g., EU-West for GDPR), manufacturing data on-premise, synchronized through event-driven replication
Network Connectivity and Latency Management
Hybrid ERP architectures live or die based on network connectivity between on-premise and cloud environments. 03/GB out) provide predictable latency and bandwidth. VPN tunnels work for non-real-time integrations but introduce variable latency of 20-80ms that makes interactive ERP forms sluggish.
- Provision Azure ExpressRoute or AWS Direct Connect with redundant circuits for production ERP workloads requiring <20ms round-trip latency and 99.95% availability
- Implement application-level health checks that detect latency spikes >50ms and automatically failover to cached local data for shop floor operations
- Use Azure Front Door or AWS Global Accelerator to optimize user-facing ERP web client traffic with anycast routing to the nearest cloud edge
- Configure WAN optimization appliances (Riverbed, Silver Peak) on both sides to compress ERP traffic and reduce effective bandwidth consumption by 60-70%
- Design the network for the cutover scenario: during migration, both on-premise and cloud ERP must coexist with bidirectional data synchronization for 2-4 weeks
Hybrid Operations and Management
Managing a hybrid ERP environment requires unified monitoring, consistent security policies, and automated failover between on-premise and cloud components. Azure Arc and AWS Systems Manager provide single-pane-of-glass management across hybrid infrastructure, but ERP-specific monitoring for transaction throughput, posting performance, and user session health requires additional instrumentation.
- Deploy Azure Monitor or AWS CloudWatch agents on both on-premise and cloud ERP servers to centralize performance metrics, logs, and alerts in a single dashboard
- Implement infrastructure-as-code using Terraform or Azure Bicep to manage both cloud and on-premise (via Azure Arc) ERP infrastructure with version-controlled configurations
- Configure automated failover: if the cloud ERP database becomes unreachable, on-premise application servers redirect to a local read-replica within 60 seconds
- Establish a unified patching schedule that coordinates cloud VM updates with on-premise server maintenance windows to prevent version drift between hybrid components
