Linux Bastion Hosts on AWS (AWS Quick Start)

This Quick Start adds Linux bastion hosts to your new or existing AWS infrastructure for your Linux-based deployments. After you deploy this Quick Start, you can layer your cloud environment with additional AWS services, infrastructure components, and applications to complete your Linux environment in the AWS Cloud.

The bastion hosts provide secure access to Linux instances located in the private and public subnets of your VPC. The Quick Start architecture deploys Linux bastion host instances into every public subnet to provide readily available administrative access to the environment. The Quick Start sets up a Multi-AZ environment consisting of two Availability Zones. If highly available bastion access is not necessary, you can stop the instance in the second Availability Zone and start it up when needed. This documentation is offered for free here as a Kindle book, or you can read it online or in PDF format at https://aws.amazon.com/quickstart/.
