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.

The chapter will start by setting up CloudWatch monitoring. We will further examine how to push custom metrics—such as swap, network, and disk space utilization—to CloudWatch. Then, we will look at SNS and how it's tightly coupled with CloudWatch to provide you with a seamless notification experience. We will further tighten our monitoring by looking at how to use CloudWatch Events...
