With the release of 9.x.67 (referred to internally as just 67) we thought that it was about time we started to talk about some of the functionality that will be included. The first one on the list is Multi-tier synchronization support.
9.1.66 and prior architecture
GO! Sync® takes information from ArcSDE® and delivers it to occasionally connected field devices when they are online.
This functionality has been available for many years now and is in operation at numerous clients. The architecture of this application prior to 67 was 2-tier.
This caused problems for some of our clients with Operating regions and slow WAN connections between them as it means data is sent multiple times from one server over the WAN to each client.
9.x.67 and onward architecture
With the 67 release multi-tier architecture is now supported where changes from the Mobile GIS Server are delivered to Staging Servers. Clients then get their data, configuration and application from the ‘closest’ staging server rather than the Mobile GIS Server.
Note: The two-tier architecture is still fully supported and is in-fact the default configuration even in 67.
Conclusion
With the 9.x.67 release GO! Sync is able to support organizations that have multiple locations and bandwidth considerations between them.
