systemd (with lowercase S and D) remains up until this day, both one of the most critical pieces of a system, and the least understood one. This talk explains how you can harness the power of systemd to solve common problems, including some that you didn't even know you had. What problems do you ask?, you’ll have to come and see.
Bring a laptop to follow along with this interactive session as we learn Kubernetes basics using kubeadm, kubectl, and other command-line tools. Attendees will learn to model portable, scaleable, and highly-available solutions using open source tools for cloud-native computing.
Observing where latency occurs in every layer of your stack is critical to understanding its performance, and that can be especially challenging when you’re building your own open source observability solution to maintain your front end. There’s less of a latency budget than you think. Measuring delays from network requests and browser operations are necessary but they do not tell the whole performance story. Knowing what delays your users are actually experiencing (and where) gives you actionable views into why your app is hung up, and how to foster your best experience possible.
This preparation session will be led by Evan Leibovitch, Linux Professional Institute. Evan will field any technical questions and help prepare you before you take the exam. Participate to learn more about the importance of understanding the objectives prior to writing your exam, the exam structure, and why obtaining your certification will be professionally beneficial. Come prepared with questions! The Linux Essentials Professional Development Certificate (PDC) also serves as an ideal stepping-stone to the more advanced LPIC Professional Certification track for Linux Systems Administrators.
The Linux Professional Institute LPIC-1 Preparation Session will be led by Kenny Armstrong, a certified trainer from Linux Professional Institute. We will field any technical questions and help prepare you before you take the exam. Participate to learn more about the importance of understanding the objectives prior to writing your exam, the exam structure, and why obtaining your certification will be professionally beneficial. Come prepared with questions!
LPIC-1 is the first certification in LPI’s multi-level Linux professional certification program.
Live patching is one tool among many to make security updates. Typically live patching is only done to operating systems and hypervisors. This presentation will briefly discuss different methods of live patching, explain in more detail one of those methods, as well as if and how a patch can be made. It will also cover practical considerations of applying a live patch. Live patching in the Xen hypervisor, which is simpler software than Linux, will be the primary example though Linux will be discussed at a high level. Some familiarity with C and what assembly is is suggested.
DevOps culture challenges traditional organizational silos, internal departmental goals, and traditional ways of working. When you're looking to introduce a change into your organization, people will have questions about what you're trying to change, why, how urgent it is, when, etc. Your case for change answers these questions BUT tailoring it to achieve specific outcomes turns your case into a powerful tool to align people and get the support you need.
How really important are mentorship and documentation to the survival of civilization? What would happen if we lost everything and had to start over, say, due to a global pandemic? We talk a lot about mentorship in the tech industry, but what do we really mean? Are we setting people up for success? In this talk, we’ll explore and seek to answer these questions, and come to some action steps to do our part.
Have you started your Cloud-Native journey? The first thing you need to do is containerize your applications. Now that you've gotten past that first hurdle I'm here to say there‚Äôs more to think about. I’ll talk about stumbling blocks that a masked enterprise called AsgharLabs had to deal with, and hopefully shed some light on things.
There are many compelling reasons motivating people to move from other databases to PostgreSQL, including security, performance, tools, and cost savings. I will share lessons learned from migrations big and small, and some approaches and tools that make migrating data to PostgreSQL painless. We will also go over how these approaches and tools can also be used for cross-server data integrations.
