Primary Cloud Extender in multi-Cloud Extender environments
The Exchange ActiveSync module now allows multiple Cloud Extender® environments in which multiple primary Cloud Extenders are supported by both On-Premises Exchange servers (Exchange versions 2010, 2013, 2016) and Office 365 servers in an Exchange environment.
Configuring multiple Cloud Extenders
You can now have a primary Cloud Extender for each Exchange cluster. For example, you can now have a primary Cloud Extender for the On-Premises Exchange cluster and a primary Cloud Extender for the cloud-based Office 365 cluster. The administrator no longer needs to designate a primary Cloud Extender.
The Cloud Extenders
collaborate with each other through a shared data area to determine which Cloud
Extender is the primary
Cloud
Extender. The
Cloud Extenders heartbeat
into the shared data area to communicate the following:
- All active Cloud Extenders are aware of other Cloud Extenders that are active.
- The first Cloud Extender to register with the shared data area assumes the primary Cloud Extender role.
- If the primary Cloud Extender becomes inactive, one of the other Cloud Extenders assumes the primary Cloud Extender role.
