What is auto-scaling? How does it work?

Autoscaling is a feature of AWS which allows you to configure and automatically provision and spinup new instances without the need for your intervention.  You do this by setting thresholds and metrics to monitor.  When those thresholds are crossed a new instance of your choosing will be spun up, configured, and rolled into the load balancer pool.  Voila you’ve scaled horizontally without any operator intervention!



With MySQL databases autoscaling can get a little dicey, so we wrote a guide to autoscaling MySQL on amazon EC2.
