Mastering Active Directory - Second Edition

Azure AD B2B

If partner businesses want to share access between their infrastructures, and both organizations are using Windows AD, then we can use AD trusts to facilitate this. This also requires additional configurations in firewalls and DNS. It also adds management overheads, as partners need to manage additional directories. In Azure, we can use Azure AD B2B to provide secure, smooth access between partners, without additional configurations or management overheads. It is just a matter of sending an automated invitation to the partner organization, and then they can complete the sign-up process in minutes. Also, it is not essential for your partner to have Azure AD in order to perform a B2B connection.
