Designing AWS Environments

By: Mitesh Soni, Wayde Gilchrist

Overview of this book

Amazon Web Services (AWS) provides trusted,cloud-based solutions to help you meet your business needs. Running your solutions in the AWS Cloud can help you get your applications up and running faster while providing the security to meet your compliance requirements. This book begins by familiarizing you with the key capabilities to architect and host applications, websites, and services on AWS. We explain the available options for AWS free tier with virtual instances and demonstrate how you can launch and connect them. Using practical examples, you’ll be able to design and deploy networking and hosting solutions for large deployments. Finally, the book focuses on security and important elements of scalability and high availability using AWS VPC, Elastic Load Balancing, and Auto scaling. By the end of this book, you will have handson experience of working with AWS instances,VPC, Elastic Load Balancing, and Auto scalingrelated tasks on Amazon Web Services.

Highly available architectures

In the previous section, we created a secure environment for our applications, by adding additional security to our VPCs. In this section, we will discuss VPC architectures, that can make the environments for our applications highly available. To make our environments highly available, we are going to deploy instances into multiple availability zones, and load balance the requests with elastic load balancing. Finally, we'll add additional resilience to our environment, by automatically scaling horizontally.

Availability zones

AWS is built on a global infrastructure, located in more than a dozen regions, including several countries in Europe and Asia, as well as Australia, the United States, Canada, and Brazil.

Each region is divided up into separate physical areas, in what AWS calls availability zones, or just AZs. The data centers are built in small, fault isolated clusters, in these availability zones, which are typically tens of miles apart. This makes a regionwide...
