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.

Section 3: Adding Scalability and Elasticity to the Infrastructure

So far, we have built our initial infrastructure. Now, it's time to add elasticity and scalability to it. We add the application load balancer in front of our Elastic Compute Cloud (EC2) instances and then add those instances as a part of the Auto Scaling group. Finally, we add the Amazon Web Services Relational Database Service (AWS RDS) database (MySQL) to make it a two-tier application.

The following chapters are included in this section:

  • Chapter 5, Increasing an Application's Fault Tolerance with Elastic Load Balancing
  • Chapter 6, Increasing Application Performance using AWS Auto Scaling
  • Chapter 7, Creating a Relational Database in the Cloud Using AWS Relational Database Service (RDS)
