By: Prashant Lakhera

Overview of this book

Amazon Web Services (AWS) is one of the most popular and efficient cloud platforms for administering and deploying your applications to make them resilient and robust. AWS for System Administrators will help you to learn several advanced cloud administration concepts for deploying, managing, and operating highly available systems on AWS. Starting with the fundamentals of identity and access management (IAM) for securing your environment, this book will gradually take you through AWS networking and monitoring tools. As you make your way through the chapters, you’ll get to grips with VPC, EC2, load balancer, Auto Scaling, RDS database, and data management. The book will also show you how to initiate AWS automated backups and store and keep track of log files. Later, you’ll work with AWS APIs and understand how to use them along with CloudFormation, Python Boto3 Script, and Terraform to automate infrastructure. By the end of this AWS book, you’ll be ready to build your two-tier startup with all the necessary infrastructure, monitoring, and logging components in place.

Setting up the AWS DLM

AWS Data LifeCycle Manager (DLM) is used to automate the creation, deletion, and retention of snapshots, which we use to back up our EBS volumes. AWS DLM comes with no additional cost and provides a complete backup solution for your EBS volumes. Some of the advantages of using it are as follows:

  • Regular backup schedule
  • Retains the backup, which is required for internal compliance and auditing
  • Deleting the old backup will reduce your storage cost

To use the Amazon DLM to manage the backup of your EBS volumes via the AWS management console, we need to go through the following series of steps:

  1. Go to the EC2 console at https://console.aws.amazon.com/ec2/, and in the navigation pane, click Lifecycle Manager under Elastic Block Store:
