> Practical DevOps guides for engineers. Hands-on tutorials on Linux, Kubernetes, AWS, networking, security, databases, monitoring, and the rest of the modern stack — written for engineers who want to understand how things actually work. Beginner-friendly, free, no signup.

aws-labs.com is a free knowledge base of 173 production-tested how-tos and tutorials covering the practical day-to-day of running and operating modern infrastructure. Each guide is a self-contained walkthrough with commands, configuration, and explanations.

The site is operated by [DevOps Team](https://devopsteam.io), a fractional DevOps/ITOps/SecOps consultancy. Articles are written by working practitioners, not marketing teams. There is no paywall, no email signup wall, and no in-article advertising.
