SCCM vs MDT
🛠 SCCM (System Center Configuration Manager)
A full-featured enterprise-grade endpoint management solution.
Primary Use:
OS deployment
Application deployment
Patch management
Compliance and configuration settings
Endpoint security
Key Features:
Supports task sequences for automating OS deployments.
Manages both operating system deployment (OSD) and
ongoing lifecycle management (updates, software).
Integrates with Intune for co-management.
Requires a central server infrastructure and SQL database.
Licensing required (via Microsoft Endpoint Manager suite).
Strengths:
Scalable for large enterprise networks.
Can deploy to devices without an OS (bare metal).
Supports PXE boot, multicast, and Wake-on-LAN.
Weaknesses:
Requires more setup and infrastructure.
Complex to manage; steep learning curve.
📦 MDT (Microsoft Deployment Toolkit)
A free, lightweight tool for image-based OS deployments.
Primary Use:
Creating and deploying custom Windows images.
Automating deployment through task sequences.
Key Features:
Works with Windows Deployment Services (WDS) or bootable
USBs.
Uses Lite Touch Installation (LTI) or Zero Touch Installation
(ZTI) (ZTI requires SCCM).
Great for labs, small IT shops, or proof-of-concept projects.
Strengths:
Free and easy to set up.
Ideal for small to medium deployments.
Offers granular control over OS image and deployment steps.
Weaknesses:
No built-in management of updates, software, or policies post-
deployment.
Limited scalability – not suited for large enterprise
environments.
Manual image updates can be time-consuming.

🏁 Conclusion:
Use MDT if you need a free, simple imaging tool for basic OS
deployments.
Use SCCM if you're managing thousands of devices, need
central control, and want to handle patches, apps, and
compliance — not just OS deployment.
In practice, MDT is often used alongside SCCM to help build and test
task sequences or images before large-scale rollout.
