## Short answer

Design a hybrid cloud architecture for ERP systems balancing on-premise and cloud workloads. Covers Azure Arc, AWS Outposts, connectivity, and data residency patterns.

**Intro:** A hybrid cloud architecture for ERP keeps latency-sensitive manufacturing execution and shop floor systems on-premise while hosting financials, planning, and analytics in the cloud. This pattern is adopted by 58% of manufacturing enterprises according to IDC's 2024 cloud survey because it balances cloud scalability with the sub-10ms latency requirements of real-time production systems.

#### Hybrid Architecture Design Patterns for ERP

**Body:** 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.

**Bullets:**

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

**Body:** Hybrid ERP architectures live or die based on network connectivity between on-premise and cloud environments. Dedicated connections like Azure ExpressRoute ($55/month for 50 Mbps) or AWS Direct Connect ($0.03/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.

**Bullets:**

- 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

**Body:** 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.

**Bullets:**

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

**Cta:** Netray AI agents design and validate hybrid ERP architectures, simulate latency scenarios, and optimize your split between on-premise and cloud workloads. Start your assessment.
