Justification for getting SCCM 2012 over using Freeware WSUS & WDS ?


Can anyone here please share some recommendation and justification of implementing Microsoft System Center Configuration Manager 2012R2 over the current freeware of WSUS and WDS ?

I'd like to know why people chose to buy the expensive SSCM license over the freeware ones.

Thanks !

With WSUS you can push out OS updates, sservice packs, drivers ...from the windows update catalog.
With WDS you can deploy OS images and software at once.
With SCCM you can do all the above separately so you have more flexibility especially if software deployment is on high demand. Very easy to do once setup but it does require quite a lot of ground work.
WAIK - Windows Automatied Installation Kit - needed for just about everything - has all the tools for WIM files (WinPE, imageX, etc) - Also contains System Image Manager (SIM or WSIM) which is used to edit unattend XML files for Vista / 7 / 2008 / R2
• WDS - Windows Deployment Services - Replaces the old RIS service - 3 main points - Boot Images - for PXE booting the PC to either WDS itself or MDT or SCCM.. Clean Install Windows (Vista onwards) as if it was from the install DVD, or capture and deploy a sysprepp'd PC - XP onwards...
• MDT - WDS with extras - alllows for custom "fresh" deployments of Windows XP onwards, and can be customized with drivers, OS Patches, Software via Task Sequences - Can be further customized by targeting TS's to Makes/Models of PC (e.g. drivers)..  Lite Touch Installations (LTI) - so you need to visit each PC - at least once (power it on and press F12) depending on the TS's
• SCCM - the creme de la creme - does everything MDT does and a heck of a lot more - it supports Zero Touch Installations (ZTI) - meaning you dont even need to go near a PC to rebuild it (Force PXE Boot, Schedule Rebuilds at a certain time), can integrate with MDT, can release software to clients, can do windows updates in more managed way.

ah OK, what about the remote support ?
because at the moment VNC is the freeware that I use for remote support desktop users.
Acronis True Image 2019 just released!

Create a reliable backup. Make sure you always have dependable copies of your data so you can restore your entire system or individual files.

The answer truthfully is more to do with the scale of your business. If it's a very small company with less than 20 people then WDS + MDT is fine. If you grow to 200 it's still OK, but you might find that there are extra needs like auditing licenses, machines and security issues. WDS is just plumbing. Even SCCM uses it.

The list is:

MDT standalone - no network involved (there's 5 people)
WSUS + WDS + AD + MDT + WAIK/WADK - 20 people
WSUS + WDS + AD + MDT + WAIK/WADK - 200 people, light users
WSUS + WDS + AD + MDT + WAIK/WADK + SQL - 200 people, light users, complex organisation with roles
WSUS + WDS + AD + SCCM + SQL + WAIK/WADK + MDT - 2000 people, heavy users with mobiles, tablets etc.

SCCM add lots of features above and beyond deployment. MDT is for OSD alone, and even if you buy SCCM you still *need* to create your images in MDT first. So, it's never and either/or question. It's just the next step up the ladder.
It adds power management, better patching, patch reporting (vital for compliance), mobile support, inventory, license metering, antivirus (Endpoint Protection), remote control and compliance management (DCM) and user-based software deployment.

Software deployment is a big reason alone as using the free AD technology works, but begins to show the strain as numbers grow. Many companies just use SCCM for OSD + app deployment with the odd report for management and never use the many other features it has which is a bit sad. It's a bit like buying a car and only using two gears. If you do decide to make the leap, look at everything it does. As striker says patching needs a bit of work but you can fully automate Patch Tuesday to push out patches and produce a lovely management friendly report with pictures.

I hope that answers your question. Striker gave you good info - this is just a more business view I guess.
