# Enterprise iOS Orchestration: Managing 500,000 Devices with ABM and DDM

Overview
--------

Managing an enterprise fleet of **500000 iOS and iPadOS devices** across **50 sub-companies** requires a shift from manual administration to automated orchestration. This guide details the integration of **Apple Business Manager (ABM)** and **Declarative Device Management (DDM)** within Hexnode UEM to facilitate zero-touch deployment, multi-user environments, and sub-second compliance enforcement.

Zero-Touch: Automated Device Enrollment (ADE) 
----------------------------------------------

For a 500-man technician team, manual setup is a logistical impossibility. Hexnode ADE bypasses the “Touch” phase of deployment entirely.

- **The Workflow:** Devices purchased through corporate channels are linked to the **Hexnode Dedicated Cluster** via ABM before the box is ever opened.
- **Supervised Mode:** ADE automatically places devices in [Supervised](https://www.hexnode.com/mobile-device-management/help/ios-supervised-mode/) Mode. This grants the highest level of administrative authority, enabling: 
    - Silent app installation and updates.
    - Global HTTP Proxy and “Always-On” VPN configurations.
    - **Non-Removable MDM:** Ensuring the management profile cannot be deleted by the end-user.

- **Setup Assistant Customization:** Technicians can suppress specific panes (Siri, Apple Pay, Screen Time, etc.), reducing “Time-to-Productivity” for the 500,000 end-users.

Managing 500000+ iOS devices: Shared iPad for Business (Multi-User Orchestration) 
----------------------------------------------------------------------------------

To maximize hardware ROI in retail, healthcare, and logistics, Hexnode facilitates the **Shared iPad** framework, allowing a single device to serve multiple shifts securely.

- **Managed Apple Accounts:** Integration with **Hexnode Access** and **Entra ID (Azure AD)** allows users to sign in using their existing corporate credentials.

- **Data Segregation:** Each user receives a dedicated User Partition. 
    - Upon logout, data is cached locally or synced to iCloud.
    - The device is immediately cleared for the next user without a full wipe.
- **Resource Optimization:** Hexnode dynamically manages the number of active partitions based on storage capacity, ensuring the fleet remains performant without manual intervention.

VPP & License Orchestration (Apps at Scale) 
------------------------------------------------

Distributing software to 500,000 devices is managed through the **Volume Purchase Program (VPP)**, ensuring financial and logistical isolation for each business unit.

- **Silent Distribution:** Apps are pushed via the **MQTT + APNS** channels. Users are not prompted for a personal Apple ID, ensuring 100% adoption.
- **License Reclamation:** When a user offboards from one of the 50 sub-companies, the VPP license can be revoked from the Hexnode console.
- **Location-Based Token Management:** Each of the 50 sub-companies can utilize its own VPP token, keeping software budgets and license ownership strictly isolated.

DDM on iOS: The Future of Orchestration 
----------------------------------------

Hexnode utilizes **Declarative Device Management (DDM)** for iOS 17+, moving from “Imperative” (Server-driven) to “Autonomous” (Device-driven) management.

- **Autonomous Enforcement:** The iPad monitors its own state (e.g., OS version, passcode compliance).
- **Instant Activation:** If a user disables a required setting, the device’s native DDM engine triggers the corrective configuration **instantly**.
- **Proactive Reporting:** The device notifies the Hexnode MQTT channel of the self-remediation event, providing real-time compliance visibility.

---------------------------------------------

- [Link ABM Account:](https://www.hexnode.com/mobile-device-management/help/how-to-deploy-apple-vpp-apps-with-hexnode-mdm/) Connect the ABM portal to the Dedicated Hexnode Portal.
- [VPP Token Isolation:](https://www.hexnode.com/mobile-device-management/help/enrollment-of-apple-devices-through-dep/#step-1-configure-ade-in-hexnode) Upload VPP Tokens for each of the 50 sub-companies.
- [Define ADE Profiles:](https://www.hexnode.com/mobile-device-management/help/how-to-add-devices-to-apple-dep/#step-2-configure-enrollment-profile) Configure profiles as “Supervised” and “Non-Removable.”
- **Enable Shared iPad:** Target Retail and Logistics Organizational Units (OUs).
- **Configure DDM Activations:** Set OS update compliance and security baselines for autonomous enforcement.
