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.

Summary

In this chapter, you have learned about one of the most popular features of AWS, Auto Scaling. Auto Scaling is a powerful and great way to reduce costs while maximizing your application's performance by intelligently scaling your environment based on demand.

In this chapter, we learned how to set up Auto Scaling both via the AWS console and via Terraform. We learned the importance of Auto Scaling and how it makes your infrastructure reliable and scalable. We also saw one real-world example of how Auto Scaling helps give us a consistent performance when demand increases and tears down instances once the load decreases. This is helpful in cases where you want to save costs.

In the next chapter, we will focus on databases and use an AWS managed database service known as Amazon Relational Database Service (RDS). We will see how by using RDS, AWS will take care of all the heavy lifting (such as patching, backup, and recovery). We will start by setting up an RDS MySQL...
