Microsoft Entra Domain Services pricing

Join Azure virtual machines to a domain without domain controllers

Microsoft Entra Domain Services provides scalable, high-performance, managed domain services such as domain-join, LDAP, Kerberos, Windows Integrated authentication, and group policy. With the click of a button, administrators can enable managed domain services for virtual machines and directory-aware applications deployed in Azure Infrastructure Services. By maintaining compatibility with Windows Server Active Directory, Microsoft Entra Domain Services allows administrators to easily migrate legacy on-premises applications to the cloud and to centralise management of all applications and all identities in Microsoft Entra ID (formerly Azure AD).

Prices are estimates only and are not intended as actual price quotes. Actual pricing may vary depending on the type of agreement entered with Microsoft, date of purchase, and the currency exchange rate. Prices are calculated based on US dollars and converted using London closing spot rates that are captured in the two business days prior to the last business day of the previous month end. If the two business days prior to the end of the month autumn on a bank holiday in major markets, the rate setting day is generally the day immediately preceding the two business days. This rate applies to all transactions during the forthcoming month. Sign in to the Azure pricing calculator to see pricing based on your current programme/offer with Microsoft.
