DESCRIPTION
In 2012 the City of Ashland Public Works Utility department required field crew workers access to utility GIS data sets in the field and on their android tablets. Within one week of making the decision to go with Amazon Elastic Cloud Computing (EC2), ArcGIS Server was up and running serving out dynamic and tiled map services to client apps deployed through ArcGIS Online. In a couple of weeks an editing feature service was deployed for redline field markups. Everything was going good until I was asked to make the actual GIS datasets available for editing. This required several weeks of planning, development and troubleshooting, and a bunch of support phone calls to get everything working right. I have a lot successes stories and a few failures to share with you. This presentation will cover; Deploying a small scale Amazon EC2 server, Configuring ArcGIS server in the cloud for web map and editing services, Using ArcGIS Online to author web maps for web browser and mobile client access, Using python and AWS API scripts for automating EC2 machine control and geodatabase replication and synchronization.

Utilizing ArcGIS Server since 2010
Spring of 2012 signed a SUELA with ESRI
Project InfoUtility crew were issued Verizon Android tabletsNeeded access to GIS mapping in the field ASAPUsers were accustomed to rich intranet web mappingIT issues and barriers to running our own serverAfter a phone call to the ever friendly folks at ESRI, I decided to look into hosting an Amazon cloud server for pushing our utility info out to the field crews.Within a week we had an Amazon EC2 server setup and serving map services to three Android tablets using the ArcGIS for Android app.
