  • TeamCity

    #<User:0x00007ec85603bcc0> Stack Overflow


    TeamCity builds then copies to each web tier via a powershell script. The steps for each server are:

    • Tell HAProxy to take the server out of rotation via a POST
    • Delay to let IIS finish current requests (~5 sec)
    • Stop the website (via the same PSSession for all the following)
    • Robocopy files
    • Start the website
    • Re-enable in HAProxy via another POST

  • Redis

    The UI has message inbox that is sent a message when you get a new badge, receive a message, significant event, etc. Done using WebSockets and is powered by redis. Redis has 2 slaves, SQL has 2 replicas, tag engine has 3 nodes, elastic has 3 nodes - any other service has high availability as well (and exists in both data centers).
