Implementing Cloud Design Patterns for AWS - Second Edition

By: Sean Keery, Clive Harber, Marcus Young

Overview of this book

Whether you're just getting your feet wet in cloud infrastructure or already creating complex systems, this book will guide you through using the patterns to fit your system needs. Starting with patterns that cover basic processes such as source control and infrastructure-as-code, the book goes on to introduce cloud security practices. You'll then cover patterns of availability and scalability and get acquainted with the ephemeral nature of cloud environments. You'll also explore advanced DevOps patterns in operations and maintenance, before focusing on virtualization patterns such as containerization and serverless computing. In the final leg of your journey, this book will delve into data persistence and visualization patterns. You'll get to grips with architectures for processing static and dynamic data, as well as practices for managing streaming data. By the end of this book, you will be able to design applications that are tolerant of underlying hardware failures, resilient against an unexpected influx of data, and easy to manage and replicate.

RBAC


Circling back to role-based access control (RBAC) now, we have touched on the importance of user, group, and role management in previous parts of this book, so let's look at how we can implement these elements in Terraform.

Directory service

If you are familiar with Microsoft Active Directory or have existing group policies you would like to apply, the AWS Directory Service will let you easily migrate your objects to the cloud. In most cases, we won't actually move them, but federate our cloud directory services with an existing directory, giving current users and groups access to the AWS Management Console and APIs:

resource "aws_directory_service_directory" "bar" {
  name = "corp.notexample.com"
  password = "SuperSecretPassw0rd"
  edition = "Standard"
  type = "MicrosoftAD"

  vpc_settings {
    vpc_id = "${aws_vpc.main.id}"
    subnet_ids = ["${aws_subnet.foo.id}", "${aws_subnet.bar.id}"]
  }
}

You should enable secure directory access on your service (LDAPS). As this is important I...
