Right click “Save as…”

Join Wade and Steve each week as they cover the Windows Azure Platform. You can follow and interact with the show @CloudCoverShow.

In this episode, Steve and Wade explain the application architecture of their latest creation—the Apathy Button. Like many other popular buttons on the Internet, the Apathy Button has to deal with the basic challenge of concurrency. This concurrency challenge arises from multiple role instancesas well as multiple threadsall trying to update the same number. In this show, you'll learn a few approaches to solving this in Windows Azure.

    Actually I was recently trying to figure out a way to do atomic increments using queues or table storage, so this gives me some good ideas. I really wanted a way that did not require proxying the requests through a web role to reduce scale-out costs, but after watching the show and seeing steve's response it looks like your approach would be best.

    Thanks... can't wait to watch what is new next week at MIX!

  • It looks like some people could care less than they did. I've been watching the progress go up but the last time I checked it was down

    37544
    37668
    37710
    37618 <-- ???

    Is the counter decrease related to caching or are you updating the code to only recording unique per site?

    Steve & Wade care, so we don't have to.

    Thanks for the episode.
