Azure AD Connect is the replacement for DirSync and Azure AD Sync, and it in simple terms allows you to integrate your on-premises Active Directory with Azure Active Directory, keeping both directories in sync with each other. This enables you to provide identities that are consistent across your on-premises services, and services in the cloud such as Office 365, or other SaaS applications without the need for separate logon credentials to private and public cloud resources.
Why use Azure AD connect?
You can integrate your on-premises and cloud resources, and give your employees a single login ID to access them.
For example, let’s say your organization uses Office 365 for documents and SaaS applications that are connected to Azure AD. Imagine how complicated it would be if your IT admin team has to manage a separate set of identities for Office 365 and SaaS applications.
With Azure AD connect, you can have a single identity for both these environments, so managing them is easy. Essentially, it’s a single tool to manage all your synchronization and sign-in experience, which means deployment is likely to be super easy as well.
Lastly, Azure AD connect provides the newest and best capabilities for you, as it replaces deprecated tools like DirSync and Azure AD Sync.
