Weeks to months after a routine upgrade from systemd 247 to systemd 248, engineers at Meta discovered a very gradual growth of memory usage in systemd-journald, from 20 MB to over 300 MB and growing. It's not a memory leak! What could it be? Come hear about how we detected it, how we tracked down the cause, what the root cause was, and how it was fixed.

This talk will review strategies and tools for managing secrets in different environments, with a particular focus on cloud infrastructure, application secrets, and secrets within the DevOps CI/CD pipeline. We will look at different approaches to secrets management, exploring processes and methodologies, best practices and anti-patterns. From here we will dive into specific tools and technologies, from open source to commercial tools.

In a world, where DevOps means almost nothing and everything, or sometimes just "Ops, but nicer to devs and with cloud and GitHub", one being among all of us is willing to stand up and laugh in the face of inertia.

Bring your DevOps rage, love and tears, and we'll distill them into 120 proof beligerance.

Being a DevOps champion means going beyond the win and delving deeper into the team/organizational culture. In this talk, attendees will learn why it's the people that matter most and how to leverage DevOps best practices along with processes to make the most out of the DevOps journey.

Configuration Management tools were a revolution when they first appeared. Gone were the days of every Sys Admin carrying around their own collection of Bash scripts to get things done. It's no surprise that they became so popular so quickly. That said, the age of Configuration Management is quickly coming to an end. Serverless and immutable infrastructure are the future. In this talk you'll hear from one of Netflix's CORE SREs about how we run on a mostly immutable infrastructure, all the ways that Configuration Management has failed over the years and why you should stop using it.

When a systems administration team is distributed globally, you need tools for managing both the technical and social components of your infrastructure. In this talk I will cover the open source tool set and strategies used by the OpenStack Project Infrastructure Team, including weekly meetings on IRC, use of code review and continuous integration for systems changes, collaborative editors when completing work during maintenance windows and more.

This session is intended to bring together anybody that debugs the Linux kernel to share best practices and brainstorm new ideas. Topics may range from .config testing, module/built-in drivers, hardware/software tools and test methods for testing specific driver subsystems, VM/scheduler/interrupt stress testing, and beyond. The discussion is targeted at Linux kernel developers, QA/test engineers, and Linux product engineers with the goal of testing Linux kernel integrity.

Achieving culture change in the technology enterprise can be daunting.    A top down approach can be risky as “culture shock” may cause attrition.    How can technologists change culture organically from the bottom?   Tools can do this incrementally as adoption increases and dramatically changes the way engineers engage work.    We will talk about using tools to achieve cultural change, and introducing products in the enterprise that incentivize standardization through inspiration not fiat.
