AWS Dynamic Inventory: Automated Host Tracking for DevOps

Managing static lists of IP addresses and hostnames becomes impossible as cloud environments scale. This text-based guide teaches you how to build a self-updating, dynamic inventory of your AWS resources to automate your deployment pipelines. By understanding how to query the AWS API, you will transition from manual tracking to robust, automated infrastructure management. You will learn to leverage resource tags, secure access controls, and structured data formats to keep your host lists accurate in real time. What you'll learn: * Understand the core concepts of dynamic inventories and cloud resource discovery * Configure secure IAM policies to grant read-only access to your AWS metadata * Query EC2 instances and resource details using the AWS command-line interface * Apply structured tagging strategies to categorize hosts by environment, role, and project * Format host data into structured JSON and YAML outputs for automation tools * Integrate your dynamic host lists with modern configuration management workflows The course starts with foundational cloud metadata concepts before guiding you through written exercises to query, filter, and format your live AWS infrastructure. This course is designed for junior DevOps engineers, system administrators, and cloud beginners who want to automate their environment tracking. No prior experience with dynamic inventory tools is required, though a basic familiarity with the AWS console is helpful. Start building automated, self-updating cloud inventories today.
