AWS Administration Cookbook

By: Rowan Udell, Lucas Chan

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.

Preface

Calculating DyanmoDB performance


DynamoDB (DDB) is the managed NoSQL database service from AWS.

As DDB pricing is based on the amount of read and write capacity units provisioned, it is important to be able to calculate the requirements for your use case.

This recipe uses a written formula to estimate the required read capacity units (RCU) and write capacity units (WCU) that should be allocated to you DDB table.

It is also crucial to remember that while new partitions will be automatically added to a DDB table, they cannot be automatically taken away. This means that excessive partitioning can cause long-term impacts to your performance, so you should be aware of them.

Getting ready

All of these calculations assume that you have chosen a good partition key for your data. A good partition key ensures the following:

  • Data is evenly spread across all the available partitions
  • Read and write activity is spread evenly in time

Unfortunately, choosing a good partition key is very data-specific, and beyond...
