Office 365 Deployment Scenarios

Introduction

In most cases companies are using Office 365 in a hybrid setup. This means, that there is an on-premise Active Directory where most of the legacy application perform their authentication against and where most user authenticate against while loggin in to their workplace machines. In addition to this on-premise Active Directory there are certain services that are served from the Office 365 cloud. In order to keep the user base in sync between the on-premise and the cloud world, Microsoft provides you with a few tools to keep them in sync, most notably Microsoft Azure Active Directory Connect.

Slave Mode

In a slave modus Microsoft Azure Active Directory Connect will sync the users from the on-premise world to the Office 365 cloud. The CoreOne Suite can be configured to await the synchronization before it performs the relative actions. If a new user is created in the on-premise Active Directory, Microsoft Azure Active Directory Connect will take that user and sync it to the Office 365 cloud and assign the appropriate licence to the user. The assignment of the licence will then lead to automatically provision other services like an Exchange Online User Mailbox.

The same is true for any modification or the deletion. Changes are done in the local on-primes Active Directory and synced by Microsoft Azure Active Directory Connect. If you are using the CoreOne Suite to manage the on-premise Active Directory you are most likely already set and there is no additional need for further configuration unless you would like to have different or additional values in the cloud directory.

Master Mode

If you do not want to use Microsoft Azure Active Directory Connect to sync the users, you can also let the CoreOne Suite actively provision and manage those identities. In this case the CoreOne Suite provisions the users, assigns the appropriate licence and manages the identity throughout the life cycle of the identity.

Combination Modus

In reality you probably are going to use a combination of those two modi. Your regulare users will be managed in the slave modus but other resources such as groups, teams or Equipment Mailboxes will be managed in the Master modus.
