Chapter 7. Manage Your Applications with Auto Scaling and Elastic Load Balancing

In the previous chapter, you learnt a lot about monitoring our AWS infrastructure, especially the EC2 instances using Amazon CloudWatch. We also created our very first alarms using CloudWatch and monitored our instance's CPU, memory, and disk utilization and performance using the same.

In this chapter, we are going continue where we last dropped off and introduce an amazing and awesome concept called Auto Scaling! AWS has been one of the first public cloud providers to provide this feature and really it is something that you must try out and use in your environments! This chapter will teach you the basics of Auto Scaling, its concepts and terminologies, and even how to create an auto scaled environment using AWS. It will also cover Amazon Elastic Load Balancers and how you can use them in conjunction with Auto Scaling to manage your applications more effectively! So without wasting any more time...
