You might be asking—is there a cloud domain controller competition going on these days? Even though Microsoft® would have you believe there isn’t an active competition in the works, it’s the right question to ask. With their Azure® Active Directory® Domain Services offering, Microsoft is trying their best to shift their customers from the on-prem domain controller to one hosted by Azure in the cloud without having IT organizations look at any Azure AD Domain Services alternatives. However, as you’ll see by reading through this post, the reality is not as simple as what Microsoft would have you believe.
Evolving Beyond the Concept of a Domain
First off, the concept that Azure AD Domain Services is a replacement to your on-prem domain controller is simply not true. Azure AD DS is meant specifically for creating domains within Azure. In fact, it is important for IT admins to understand that Azure Active Directory is not Active Directory in the cloud, but rather, an extension to the on-prem AD. The song remains the same for Azure AD DS as well.
Second, and perhaps more importantly, the concept of the domain is a dying approach that’s rapidly fading away. Thankfully, networks today are no longer all Windows®-based and on-prem. The progress is needed and only natural. The ‘domain’ that a user operates in can now include a wide range of other types of IT solutions, such as AWS®, Mac® and Linux® machines, web applications such as G Suite™, Salesforce®, Slack, GitHub™ , and others, file servers such as Box™ or NAS appliances, and WiFi networks. All of these IT solutions depart from the traditional concept of control over domain resources, requiring a dedicated server for authenticating user identities.
Third, the domain controller has served a wide variety of functions for IT networks. These functions include being their DHCP and DNS. Modern networks don’t need those services anymore as their wireless access points and other pieces of infrastructure effectively handle those functions.
