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 7: Creating a Relational Database in the Cloud using AWS Relational Database Service (RDS)

In the last chapter, you learned how to use the Auto Scaling group to scale in and scale down your resources based on demand.

In this chapter, we'll look at AWS Relational Database Service (RDS), to manage database service by using AWS. Using AWS RDS, it's easier to set up and manage databases in the cloud. When you use AWS RDS to create your database, AWS will take care of some of the heavy lifting, including the following:

  • Automated patching
  • Automatic failover
  • Backup and recovery
  • The point-in-time recover

In this chapter, we will look at various RDS offerings, and then we deep dive into the offering covering MySQL. We will start with setting up MySQL in multiple Availability Zones, which is useful in case of disaster recovery. Then we will further look at setting up a read-only replica, which takes away all the heavy read load from the master...
