Implementing Cloud Design Patterns for AWS - Second Edition

By: Sean Keery, Clive Harber, Marcus Young

Overview of this book

Whether you're just getting your feet wet in cloud infrastructure or already creating complex systems, this book will guide you through using the patterns to fit your system needs. Starting with patterns that cover basic processes such as source control and infrastructure-as-code, the book goes on to introduce cloud security practices. You'll then cover patterns of availability and scalability and get acquainted with the ephemeral nature of cloud environments. You'll also explore advanced DevOps patterns in operations and maintenance, before focusing on virtualization patterns such as containerization and serverless computing. In the final leg of your journey, this book will delve into data persistence and visualization patterns. You'll get to grips with architectures for processing static and dynamic data, as well as practices for managing streaming data. By the end of this book, you will be able to design applications that are tolerant of underlying hardware failures, resilient against an unexpected influx of data, and easy to manage and replicate.

Chapter 8. Application Virtualization - Using Cloud Native Patterns for Your Workloads

Virtualization is not a new technology. However, the cloud has allowed us to abstract our programs further away from the underlying hardware. We began our journey creating AWS EC2 instances. The mechanism that the instance uses is the virtual machine (VM). Using a VM gives us the ability to share hardware at the operating system level. Windows, Linux, and iOS instances can all be run on VMs. Putting a hypervisor on top of the bare metal hardware gives Amazon the ability to run multiple OSes on a single piece of hardware or host. Packing many VMs onto a single host is a great way to increase utilization of expensive servers. Amazon's introduction of this model to the public created the modern-day cloud. 

While AWS were selling, and securing, their spare capacity for multi-tenant use, the cloud model was extended into other areas. Networking was a big part of the second wave of virtualization. Isolation of...
