Horizontally scaling a web app has become a total no-brainer in the last few years. PaaS offerings like Heroku allow you to add a “dyno” with the click of a button and container technology such as Docker has enabled the same ease to scale your your own deployment. By now it has become a standard in all mayor cloud providers such as AWS to allow you to auto-scale your app.
