GeoServer on AWS

In planning my 8 week course, I realized early on that I wanted to devote a portion of the class to cloud computing. If you’re not familiar with cloud computing, it is the ability to tap into computing resources on an as-needed basis. It’s a fairly old idea that unfortunately has been elevated to buzzword status when discussing modern computer systems. Cloud computing is worth your excitement as anyone – large organizations down to single users – can tap into cloud-based resources. Amazon Web Services, perhaps the largest, definitely the most well-known cloud computing provider, allows you to run servers on their infrastructure for only pennies per hour.

Why does this matter to you? As a GIS person, you may think that dealing with servers and creating websites are the stuff of the IT department. The trend in GIS is moving away from static maps and paper media to rich, interactive experiences provided by web-based map services. To provide the best experience – in terms of interactivity, efficiency, and aesthetics or branding – to your users, you will likely need your own GIS server. In the past, purchasing a server would take months of negotiation with IT, Purchasing, and other levels of bureaucracy within your organization. If you wanted a GIS server for a personal project, unless you are incredibly wealthy, the capital investment alone would have made your project infeasible. With cloud computing, you can get started with just a credit card, starting small and scaling your resources as needed.

I have been developing an AMI for use in the class that will have you up and running with a GIS server in a matter of minutes. This server will be configured with some common open source software that you will be able to use to host your own web maps and GIS services on Amazon’s infrastructure. GeoServer is an open source GIS server that will allow you to share your GIS data via web maps, map tiles and through KML. While this machine image does not have ArcGIS installed, there are some open desktop GIS options available. I’ve gone the open source route so that upon completion of my course, you can keep your web/GIS server running without licensing or maintenance costs. You would just need to pay Amazon for the time the server is active. For those of you that are a 100% ESRI shop, don’t worry, I will have an AMI with ArcGIS Server 10 available for some assignments. Once I have fully tested the AMI, I’ll gladly share the AMI id here.

If you’re interested in getting hands-on exposure with web maps, GIS servers and cloud computing environments, enroll in my course. Feel free to ask me any questions beforehand via Twitter or email.
