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.

Chapter 10: Centralizing Cloud Backup Solution

As system administrators or DevOps engineers, we all understand the importance of backing up. It's the first place we all check in the case of loss of data or disaster. Because of the cloud's dynamic nature (the instance can come and go at any time), it becomes challenging to decide which data to back up. We also need to decide how long we need to keep the backup, as the type of data and how much data we need to store will both incur a cost.

This chapter will start by looking at AWS's various backup solutions and which one you should choose under which condition. We will then move on to the Data Lifecycle Manager (DLM), which will help automate the process of snapshotting the EBS volume. Then we will look at the Simple Storage Service (S3), one of AWS's most reliable backup offerings, and how to automate backing up files in S3 using the command line. Finally, we will look at how we can transition our data to Glacier...
