Overview of this book

AWS is an on-demand remote computing service providing cloud infrastructure over the internet with storage, bandwidth, and customized support for APIs. This updated second edition will help you implement these services and efficiently administer your AWS environment. You will start with the AWS fundamentals and then understand how to manage multiple accounts before setting up consolidated billing. The book will assist you in setting up reliable and fast hosting for static websites, sharing data between running instances and backing up data for compliance. By understanding how to use compute service, you will also discover how to achieve quick and consistent instance provisioning. You’ll then learn to provision storage volumes and autoscale an app server. Next, you’ll explore serverless development with AWS Lambda, and gain insights into using networking and database services such as Amazon Neptune. The later chapters will focus on management tools like AWS CloudFormation, and how to secure your cloud resources and estimate costs for your infrastructure. Finally, you’ll use the AWS well-architected framework to conduct a technology baseline review self-assessment and identify critical areas for improvement in the management and operation of your cloud-based workloads. By the end of this book, you’ll have the skills to effectively administer your AWS environment.

Creating and populating an S3 bucket with custom resources

As discussed in the introduction to CloudFormation in Chapter 1, AWS Fundamentals, it's common for there to be cases where you need more advanced behavior than what is available by default in CloudFormation. Before custom resources, this led AWS developers down the path of doing most of their automation in CloudFormation, and then running some command-line interface (CLIs) commands to fill in the gaps.

Fast forward to today, and the emerging pattern is to use a custom resource to delegate to an AWS Lambda function. Lambda can fill in the gaps by making API calls on your behalf. While it's also possible to create a custom resource that communicates with your custom code via a Simple Notification Service (SNS), and a compute resource such as an Elastic Compute Cloud (EC2) instance, Lambda should be your first...
