Imagery can add valuable information and context to a wide array of GIS projects. For example, you can detect impervious surfaces for storm water management, map and manage riparian corridors, or track what’s changing in your county. Sometimes, though, incorporating … Continue reading
Recently, templates have been added to the ArcGIS help that you can use to launch ArcGIS Server instances on Amazon Web Services (AWS) using AWS CloudFormation.

This sort of architecture, with redundant ArcGIS Server instances accessed through an ELB, is referred to as a siloed architecture, because each ArcGIS Server instance is not dependent on any of the other ArcGIS Server instances. If one of the ArcGIS Server instances goes down, the ELB can connect to one of the other instances with little to no down-time, making it ideal for users who require high-availability with redundancy.
