How do we respond to changing demand? During peak times we have a lot of traffic, but outside of those hours there is very little demand.

Auto Scaling is elastic, meaning it can provision additional resources as necessary, and de-provision resources when they are no longer needed. In this video, we'll meet Auto Scaling, and have a look at what it can do.
