Vapor with Docker based deployment and autoscaling

This might be a stupid question but how (or is it at all) is the auto scaling handled when using Vapors Docker based deployments?

I have a site running on an environment described above and it is usually having a very heavy traffic at the beginning of January because of the campaigns and the nature of the site itself. So my concern is that will the service be up and running smoothly like it has done since the beginning of the February when deployed for the first time with Vapor?
