# Enterprise Scalability: Architecture and Infrastructure for High-Density Fleet Management

 
 
 Enterprise MDM Scalability Architecture: 50,000+ Endpoints | Hexnode UEM
 
  **Architecture Snapshot:** Hexnode UEM utilizes a **Persistent Connection Model (MQTT/WebSockets)** and a **Decoupled Control/Data Plane** to manage 50,000+ endpoints. By offloading heavy payloads to a Global CDN (Amazon CloudFront) and maintaining real-time TCP sockets, Hexnode eliminates the “Thundering Herd” bottleneck and ensures command latency of **< 500ms**.

I. Architecture Overview: The Persistent Connection Model
---------------------------------------------------------

Traditional MDM polling models create massive server strain. Hexnode uses a **WebSocket-based persistent connection** model for real-time responsiveness at scale.

- **Technology:** Long-lived TCP connections (MQTT) on ports 443 and 8883.
- **Efficiency:** Negligible CPU consumption compared to discrete HTTP handshakes.
- **Performance:** Commands reach 99% of a 50k fleet in sub-500ms intervals.

II. Decoupling the Control Plane and Data Plane
-----------------------------------------------

Hexnode separates **Control Plane** (Instruction logic) from the **Data Plane** (Payload delivery) to prevent console bottlenecking during large rollouts.

### The Global CDN Shield

Software deployments utilize high-durability **Amazon S3** storage and **Amazon CloudFront** with 200+ global PoPs.

- **Aggregate Throughput:** 40+ Gbps via nearest CDN nodes.
- **Security:** Time-limited, signed URLs ensure secure edge delivery.

III. Resilient Software Distribution (MSI, MSIX, EXE)
-----------------------------------------------------

Intelligent client-side agents handle high-concurrency transfers with the following features:

- **Chunking & Checkpointing:** Resumes interrupted downloads from the last successful block.
- **SHA-256 Verification:** Ensures data integrity across 50,000 devices.
- **Validation:** Post-install checks via Registry Keys or File Paths.

-------

Hexnode’s architecture is engineered for the **“Thundering Herd.”** By decoupling command logic from data delivery, Hexnode provides the infrastructure necessary for Global Enterprise Orchestration.

**Pro Tip:** Use **Dynamic Groups** to automate assignments based on subnet or IP range. This ensures high-bandwidth application updates only occur on designated high-speed links.
