ONLINE Enhance Site Reliability With HAProxy

Site Reliability Engineers will love this.

First, we'll setup sixteen nodes: two HAProxys and 14 HTTPd servers.
Then, we'll configure SSL off-loading and an HTTP to HTTPS redirect.
Then, we'll stop any single node.
Then, we'll stop all the nodes in a region.
Then, we'll put up a maintenance gate. (That's where we push a partially-tested change into production, and allow the QA engineers to complete testing, while everyone else gets a maintenance page.)
Finally, we'll remove the source filter so the site runs normally.

If this all goes as planned, we will celebrate joyously.
