What is a Domain Controller? | JumpCloud Video


Hey, it’s Vince with JumpCloud®. Welcome to another episode of our “What Is?” video series. In this episode, we’ll be talking
about Domain Controllers. So, what is a domain controller? A domain
controller is a server that functions to authenticate user identities and
authorize their access to IT resources. These IT resources generally include
things like systems, applications, file storage systems, networks, and really
anything else that needs to be administered within an organization. This
collection of resources is known as a domain, and a Domain Controller helps to
ensure that only the correct users can access domain bound resources. Think of
it like the gatekeeper in charge of controlling who can access your digital
kingdom. Domain Controllers are used in conjunction with a directory services
database, also known as an identity provider (IdP), which stores user information such as usernames and passwords. This enables the Domain Controller to
leverage the identity provider as the source of truth for verifying user
identities. For example, when a user attempts to log into the system they use
for work, they are typically challenged to provide
a username and password. Once provided, the user credentials are routed to the
domain controller, which then authenticates them against the directory
services database. If the credentials submitted by the user matched those
stored in the directory services database, the Domain Controller will
authorize access to domain bound resources. If not, the domain controller
will prevent the user from accessing domain bound resources. However, while
Domain Controllers are certainly effective, they represent the old way of
doing things in many ways. This is primarily because they were designed in
the late 1990s for on-prem, Microsoft based environments with Active Directory
serving as the core identity provider. Of course, this wasn’t an issue back when
everything revolved around Microsoft, but IT environments don’t work like that
anymore. Today, IT organizations are shifting
everything they can to the Cloud, leveraging Windows, Mac, and Linux systems, web applications, third-party storage solutions, wireless networks, and more.
Traditional Active Directory implementations struggle to manage the
vast majority of these new innovations. Fortunately, JumpCloud Directory-as-a-Service® effectively eliminates the need for an on-prem identity management
infrastructure by shifting the concept of the core identity provider to the
cloud. JumpCloud also takes the concept of Directory Services a step further by
offering support for all three major operating systems, web applications, cloud and on-premise storage solutions, wired and wireless networks, and more. As a result IT, organizations can continue to securely manage and connect their
users to the IT resources they need throughout their modern domain, but
without anything on-prem. These are a few of the reasons why we like to think
of JumpCloud Directory-as-a-Service as Active Directory reimagined. Contact JumpCloud today if you’d like to learn how the directory as a service platform can
benefit your organization. You can also sign up for a free account and explore
