Overview of this book

This book is aimed at architects, solution providers, and those of the DevOps community who are looking to implement repeatable patterns for deploying and maintaining services in the Amazon cloud infrastructure. Prior experience using AWS is required as the book focuses more on the patterns and not on the basics of using AWS.

Database replication pattern

The first pattern we will discuss will cover fault tolerance. To maintain zero-downtime to an end user will be a master-client configuration with full replication of data. It is one thing to have a backup of the actual data, but it is important to be able to continue to serve requests even if the data center hosting the instance experiences issues or upgrades, and causes a termination. Consider another scenario in which the database requires system-level updates that would cause it to not be available.

This could be alleviated by having a separate up-to-date instance in a different availability zone. We will first create our master and prepare it to be a MySQL master instance. Launch an EC2 instance from the AWS Linux AMI and SSH into it when it is ready:

$ sudo yum install -y mysql mysql-server >/dev/null 2>&1
$ sudo sed -i.bak 's/\[mysqld\]/[mysqld]\nlog-bin=mysql-bin\nserver-id=1/g' /etc/my.cnf
$ sudo service mysqld start >/dev/null...
