This articles describes “What you need to know before integrating on-premise AD with Azure Active Directory and MFA”. Azure Active Directory (AAD) is a Cloud Identity and Access Management solution that provides directory services, application access management, and advanced identity protection. Its single sign-on (SSO) and Multi-Factor Authentication (MFA) capability help protect employees from cyberattacks. Please see the following guide Azure Active Directory integration with on-Premise AD using PTA, and Microsoft Azure Multi-Factor Authentication (MFA).

There is a slight difference as Windows Active Directory is focused on securing Windows desktops and servers on-premise. While AAD is all about web-based authentication standards such as OpenID and OAuth.

It might interest you to know that, Microsoft offers open programs to Government Organization and Educational Institution which allows the initial purchase of 5 or more licenses and this depends on your eligibility. Here are the different license programs available for the open program.

Open Value: This program is basically for small and medium-scale companies with relatively few desktops. It also has software assurance, technology training courses, and product support, etc. The license is valid over the total years of agreement. Meaning the total cost of the license can be spread through the entire subscription period.
Open Value Subscription: It provides the lowest budget upfront of the open program options. With the flexibility to reduce the total licensing cost in the future if the need decreases. Here the software is not purchased but subscribed to and the monthly costs are lower.
Open License: One-time payment but grants unlimited use of software (i.e., upfront payment in a large sum). In this program, the five license minimum initial purchase is waived. This is not ideal as it is difficult to tell, how many licenses and updates would be needed in the coming years. This has technical support included.
