Alternatively, Elasticsearch itself is run by a company called elastic and they have a paid version, which contains something called x pack, which facilitates this as well. So you can go for either a reverse proxy which authenticates users, or the paid version of the application. All you need is a key value store, which has a key fob where the front end IP is the current front end version. And then to run your rolling deployments, you’d start a new front end version, check that it was alive, and then you just change the key in the hash table to point to the new one. They’re also quite powerful, longer running tasks, like downloads can continue running in the old version of the application after traffic is switched over to the new version. So if a user has an established connection to green, and you’ve switched everyone else over to blue, that connection can continue finishing whatever it was doing.
For a very concrete example, which is about as close as we’re going to get to code in this set of videos, let’s look at this nginx configuration. Again, let’s consider the myrn app from elsewhere in the academy DevOps series. It’s almost like taking auto scaling, so provisioning resources as the required and doing it very quickly on very small time intervals. All this configuration does is wait for tests to pass, check that the branch is the main branch, and then use the SSH key to deploy a new version of the application.

So if you’re running two things in parallel, Linux will make sure that the right amount of processors are dedicated to both. So with all that in mind, let’s talk about Linux in the abstract. So what Linux really helps you do is take care of four things when you’re writing programs, it takes care of memory. So programs need memory to do things, memory is also known as Ram. And since you only have a finite amount of it, Linux itself needs to figure out which programs will get which sections of memory, so which ram sticks will have which programs running on them.
