Implementing Cloud Design Patterns for AWS

Summary

In this chapter, we went through some very basic Cloud patterns for instance resiliency. We covered how to make volume level backups of volumes, to help guard against data loss across availability zone failures. We also covered how to create base AMIs, which can be reused as stamps. We touched upon some examples of scaling up by increasing virtual machine hardware specs, and how to scale horizontally using instance alarms and auto scaling groups. Lastly, we covered how to improve performance and modify the size of instance volumes without shutting down the running instance.

In the next chapter, we will cover some more complicated patterns aimed towards highly-available applications, or applications that cannot have downtime.
