AWS for System Administrators

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.

Transitioning S3 data to Glacier using a lifecycle policy

You can define a lifecycle policy where you can define the action that S3 takes during an object's lifetime. Some examples of these actions are deleting an object after a specified time, archiving objects, and transitioning to another storage class. A lifecycle policy can be applied to all objects or a subset of objects in a bucket. In this section, we will see how to transition S3 objects to Glacier using the lifecycle policy. The Glacier is the data-archiving and long-term secure and durable solution offered by AWS at an extremely low cost. Using Glacier, you can store your data cost-effectively for months, years, or even decades. To achieve this, you need to go through the following series of steps:

  1. Log in to AWS S3 console at https://console.aws.amazon.com/s3/ and in the bucket list, select the bucket in which you want to create the lifecycle policy. For example, in this case, we can choose the my-backup-bucket...
