A view from the clouds: Cloud computing for developers
with Tags: amazon_machine_image X
About two weeks ago, I had the opportunity to work with the WebSphere sMash, DB2, and Rational teams on a pretty exciting project. It started during a meeting with the sMash team in which they decided to build a sample application to demonstrate at the Web 2.0 Expo in San Francisco last week. Given the lead team the first thought was to simply show off the application at various IBM expo booths. However, we quickly decided the best way to show off the coolness of sMash was to put it in the hands of users. This led us down a path that would include Rational EGL capabilities, the WebSphere sMash Amazon Machine Image (AMI), and the DB2 AMI.
In a little over a week, we delivered a meaningful Web 2.0 application and put it in the hands of conference attendees. Using WebSphere sMash, we produced services that allowed users to view and search for booths at the conference. Each booth at the conference started with a list of keyword tags, and users could add more tags to let other users know what to expect at the booth. We also delivered a Buzz feature that displayed an aggregated feed from both Twitter and Flickr containing entries about the Web 2.0 Expo.
The Rational team, which was already working on an EGL application that would run on attendee handhelds, leveraged the services from our new sMash application, being hosted on the Amazon EC2 infrastructure, to add to their capabilities. Our decision to host the sMash application on EC2 was driven by two factors. The first was that we had virtually no time to go through the in-house server acquisition process. Second, given sMash’s capabilities to export and import applications, we were easily able to transfer our local application copy to the AMI instance with no code change. Once the application was imported into the running AMI instance, we changed a single configuration file to reference our newly running DB2 AMI instance which stored the booth data for the expo.
I just thought I’d share this example to highlight a couple of cool technologies, Rational EGL and WebSphere sMash, and to illustrate a scenario in which the IBM Amazon Machine Images deliver value. If you have any questions or want to see some of the application code, send us an email. Here's a couple of screen shots of the application:
