13 Achieving high availability: Availability zones, autoscaling, and CloudWatch

This chapter covers

Recovering a failed virtual machine with a CloudWatch alarm
Using autoscaling to guarantee your virtual machines keep running
Understanding availability zones in an AWS region
Analyzing disaster-recovery requirements

Imagine you run an online shop. During the night, the hardware running your virtual machine fails. Your users can no longer access your web shop until the next morning when you go into work. During the eight-hour downtime, your users search for an alternative and stop buying from you. That’s a disaster for any business. Now imagine a highly available web shop. Just a few minutes after the hardware failed, the system recovers, restarts ...
