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.

Introducing AWS Transit Gateway

AWS Transit Gateway is a network service using which customers can connect their on-premises VPC using a single gateway. A transit gateway works like a virtual router, and you can connect the following resources to your transit gateway:

  • One or more VPCs
  • One or more VPN connections
  • One or more direct connections
  • One or more transit gateway peering connections

The following diagram shows the workflow of AWS Transit Gateway:

The features of AWS Transit Gateway are as follows:

  • It can scale horizontally (for example, three VPN connections every 1.25 Gbps combined will give 3.75 Gbps).
  • It can scale up to 5,000 VPCs.
  • It uses hub-and-spoke network topology.
  • 50 Gbps of max throughput tested by AWS so far.
  • Support for direct connections.
  • Supports 10,000 routes in each route table (for VPC, the limit is 100).
