Application servers receive requests from the console and device users and process the data and results. No persistent data is maintained on these servers, but user and device sessions are maintained for a short time.

High availability is achieved by using load balancing and session persistence. See Monitoring for information on health checks on the servers. The following table outlines both for each AirWatch component:

Timeout Value

Console

Yes*

Source IP-based persistence 60 minutes

*The Scheduler and Directory Sync services must be active on only one Console server. All other services/endpoints of the Console can be load-balanced in an active-active configuration.

Device Services

Yes

Source IP-based persistence 20 minutes

AirWatch Cloud Messaging

Yes

Persistence based on parameter awcmsessionid in either the URI or HTTP Header.

N/A

VMware Tunnel (Per-App Tunnel)

Yes

Source IP-based persistence*

30 minutes
*Persistence is not required if the short-lived TCP connections are not interrupted while they are active.
VMware Tunnel (Proxy) Yes Source IP-based persistence 30 minutes

Secure Email Gateway

Yes

Source IP-based persistence Configure to be the same as the persistence timeout value for your Exchange ActiveSync Servers based on recommendations from the Mail Solution vendor.
Content Gateway Yes Not required N/A
Remote File Storage Yes Not required N/A

VMware Enterprise Systems Connector

Not required (see Note)

Not required N/A

API (SOAP and REST)

Yes

Source IP-based persistence  
Note:

 The AWCM component automatically load balances traffic from the VMware Enterprise Systems Connector. It does not require a separate load balancer because there are no incoming connections. To accommodate extra users as part of your sizing requirements you can deploy multiple VMware Enterprise Systems Connectors, which are all load balanced by AWCM.
