## AWSDevOpsExamTips
Autoscaling.
◾Understand autoscaling inside and out.
◾Make sure you know the differences between deploying with and without Cloudformation (as there are some deployment methods you can do with Cloudformation that you can’t without) and the command or JSON syntax to perform them.
◾Understand lifecycle hooks and the autoscaling stages they run in
◾Understand launch configurations and how they work and are updated (hint: You must replace them)
◾Understand why you may need to place an instance into STANDBY state

•Elastic Beanstalk.
◾You’ll need to know this to an advanced level.
◾Understand what stacks Beanstalk supports natively and how you would deploy a stack it doesn’t (hint: Use Docker).
