TeamCity is our main continuous integration server. It starts creating builds and running tests based on commits that we make in our hosted bitbucket repositories. From there, we have a set of configuraitons that can deploy the built and tested artifacts (web app, batches, db, etc...) to a stage or production server. We still release manually, but we release often, and TeamCity has nice features to help us roll back when things don't work out as planned.

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

I'm using a selfhosted TC as Referenceplatform, and use travis with another configuration.
