We will demonstrate how using Chef and AppFirst you can automate scaling out and down a multi-tiered web application. As Chef builds out the multi-tier stack, it will dynamically add the AppFirst collectors to the servers it’s executing on. Once this is running we will drive load to our web application which triggers an AppFirst alert as utilization thresholds are met. Based upon receiving the alert Chef automatically deploys another web server with an AppFirst collector and adds it to the load balancer. Using AppFirst’s UI we’ll see that our web application is now handling the load without any problems.
