Summary

Throughout this brief introduction to AWS, we learned not only the background and industry shift into virtualized infrastructure, but also where AWS fits in with some competitors. We not only discussed the kinds of problems AWS solves, but also the kinds of problems that can be encountered in Cloud infrastructure. There are countless unique processes to be solved with this dynamic paravirtual environment. Picking up consistent patterns throughout this book will help to strengthen applications of many forms against these issues. In the next chapter, we will go over some basic design patterns. It is one of the easier topics and covers data backups through instance snapshots, replication through machine imaging, scaling instance types, dynamic scaling through CloudWatch, and increasing the disk size when needed. These patterns help solve common provisioning issues for single instances.
