Backstory – why use RGA in the first place?

Microsoft is investing heavily in cloud-based solutions and this means that on-premises solutions will be phased out to a greater extent. This also comes to device management and therefore, more and more companies are embarking on their journey towards the cloud and all the benefits that come with it. To kick-start this transition, Microsoft has developed the concept or terminology called “Co-Mangement” where devices have the SMS Agent and Intune agent installed at the same time and where sub configurations in the form of workloads from ConfigMgr can be moved in phases to be managed in Microsoft Endpoint Manager  (Intune) instead. Co-Management will not be covered in this article, but you can read more about it in Microsoft docs. What is interesting about this technology is that we can move Windows patching to the cloud as a stand-alone element.

For handling mobile devices and desktops, Microsoft Endpoint Manager (Intune) is the way to go and is a technology under strong development. WSUS with SCCM, which many system administrators have used for patching PCs, is not an option in the future. For a replacement, Windows Update for Business (WUfB) is the solution. You can read more about WUfB here Microsoft docs.

There are many pros and cons between the two technologies – to boil it all down – WUfB with Endpoint Manager does not share the strict control that you get with SCCM with in-depth reporting and limitation of patches to computers using collections and where you distribute patches. But WSUS, on the other hand, is a heavy and old technology that will most likely not be developed much further.
Another challenge with WUfB is that all updates come from the cloud and you will put a lot of pressure on your WAN line if you do not make your rollout in phases. Especially in large enterprises with thousands of devices. This is exactly the the challenge RGA can solve.

“So how do we stay control when we move the workload from WSUS to WUfB?”

As stated in the Microsoft docs we can only limit patches and control the rollout on the client using CSP profiles to defer or pause updates – bummer… that means we must segregate devices into groups like collections in SCCM to control the configurations on the clients and stay in control and do phased rollouts.
