Overview of this book

Amazon Web Services (AWS) is a bundled remote computing service that provides cloud computing infrastructure over the Internet with storage, bandwidth, and customized support for application programming interfaces (API). Implementing these services to efficiently administer your cloud environments is a core task. This book will help you build and administer your cloud environment with AWS. We’ll begin with the AWS fundamentals, and you’ll build the foundation for the recipes you’ll work on throughout the book. Next, you will find out how to manage multiple accounts and set up consolidated billing. You will then learn to set up reliable and fast hosting for static websites, share data between running instances, and back up your data for compliance. Moving on, you will find out how to use the compute service to enable consistent and fast instance provisioning, and will see how to provision storage volumes and autoscale an application server. Next, you’ll discover how to effectively use the networking and database service of AWS. You will also learn about the different management tools of AWS along with securing your AWS cloud. Finally, you will learn to estimate the costs for your cloud. By the end of the book, you will be able to easily administer your AWS cloud.

Publishing custom metrics in CloudWatch


Once you get used to using CloudWatch, it is highly likely that you will want to see more than just the built-in AWS metrics.

One of the most common metrics users ask for after starting to run servers in EC2 is memory usage; the built-in metrics for EC2 instances are CPU utilization, network in/out, disk reads/writes, and status—memory is not included by default!

This recipe will show you how to feed the amount of memory inuse on your Linux instances to CloudWatch, so that you can see them alongside the other instance metrics.

Note

Knowing how utilized (or not) your instances are is a key component in choosing the right instance type to use for your workloads. Getting it wrong can cost you a lot of money!

Getting ready

You will need an EC2 instance running Linux, with the AWS CLI tool installed to perform this recipe. If you use an instance based on AWS Linux, you will have the AWS CLI tool installed for you.
