# VPC Peering for UEM: Architecting Private Connectivity at Scale

For enterprise environments managing high-density device fleets up to 500,000 devices, network latency and security are critical. Hexnode Dedicated Connectivity provides a private, high-speed bridge between your Dedicated Hexnode Cluster and your internal corporate network, bypassing the public internet to ensure seamless, “zero-latency” management.

**The Private Bridge: VPC Peering**
-----------------------------------

Standard UEM communications typically travel over the public internet. With **VPC Peering**, Hexnode establishes a direct routing connection between the Hexnode AWS/Azure environment and your corporate VPC.

### **How it Works**

Traffic remains entirely within the cloud provider’s private network backbone. This is essential for secure communication with internal systems such as:

**1. Identity Providers (IdP)
2. Public Key Infrastructure (PKI)
3. Domain Asset File Systems (DAFS)** 
### Key Technical Benefits

- **Latency Reduction**: Experience a 40–60% decrease in latency compared to public routing.
- **Enhanced Security**: By keeping management traffic off the public web, you eliminate several vectors for Man-in-the-Middle (MITM) attacks.
- **Simplified Routing**: Internal resources see Hexnode traffic as “local” traffic within the peered CIDR block.

**Dedicated Egress (Static IPs)**
---------------------------------

Large-scale organizations with multiple sub-companies often face “Security Over-reach”—where overly strict firewalls inadvertently block management traffic. To solve this, Hexnode utilizes **Dedicated Egress Points**.

- **Immutable Static IPs**: Your dedicated cluster is assigned a specific set of permanent Static IPs.
- **The Workflow**: Instead of allowlisting broad, rotating IP ranges, your 500-man technician team and 500,000 devices only need to allowlist these specific, unchanging IPs in local firewalls.
- **Consistency**: This ensures that patch deployments and inventory syncs are never interrupted by regional firewall updates.

**Optimization for Global Scale**
---------------------------------

To maintain performance across continents, Hexnode employs sophisticated routing and bandwidth management:

### **Geo-Proximity Routing**

Hexnode utilizes regional connectivity nodes to minimize the physical distance data must travel.

- **Example**: A device in Singapore connects to a regional Asian node, while a device in London hits a European node.
- **Result**: All regional traffic is aggregated and fed back into the master VPC via optimized paths, preventing the “long-haul” lag common in centralized global systems.

### **Bandwidth Guarantees**

To prevent “bottlenecking” at the network edge during massive inventory syncs or global patch deployments:

- **Dedicated 10Gbps+ Pipes**: We provide high-throughput capacity to ensure that even peak-load events do not degrade performance for the end-user or the admin console.
