The introvert’s guide to Red Hat Summit

Events like Red Hat Summit fill me with excitement and, admittedly, a bit of trepidation. Thousands of people, a schedule packed with informative and useful sessions, and opportunities to meet and talk with folks doing exciting work in open source sounds great. It also, well, sounds a bit exhausting if you’re an introvert. It doesn’t have to be, though, and Red Hat wants everyone to feel welcome, comfortable, and able to fully enjoy the event. With that in mind, read on for some strategies and resources for success.

Introverts aren’t (necessarily) misanthropes, we just tend to like smaller gatherings and less noisy and intense social situations. Even those can be fun, in limited doses. The thing about a large conference like Red Hat Summit, though, is that it’s a huge helping of people and activities turned up to 11. Don’t worry, you can still go and have a great experience, it just takes a little bit of planning.

Kubernetes Cluster vs Master Node

In Software engineering, a cluster resembles a group of nodes that work together to distribute the work load. Additionally clustering helps in fault tolerance, by having a cluster acting as a secondary (backup) to a primary cluster.

You may have read some of the release notes or press coverage from the recent release of OpenStack Stein, in which case you’ll know that Stein introduced multi-factor authentication receipts for Keystone. This really just completes the work that was originally begun in the Ocata release, making it easier to implement a challenge/response mechanism in your OpenStack environment. Multi-factor authentication is quickly becoming the norm in everything from free online email services, to social media sites and more – catching up with the security that most, if not all online banking services have been offering for some time now.

How Big is a Container, Really?

One of the first questions in any discussion about cluster sizing tends to be “How many containers are you running?”. While this is a good data point (especially if you are pushing the scheduler to its limit) it doesn’t show the whole story.
We tend to abstract out a container as this homogeneous building block that represents any workload.

This abstraction has a lot of value for learning how containers work and how the system treats all workloads similarly (which is hugely valuable). However, it falls down when we start looking at planning our hardware requirements.

How I fell in love in Nashville

It was a week of firsts. You see, I’m a ‘3.5-month newbie’ to SUSE, working remote and supporting the SAP alliance within a Global capacity. Last week was my first time in Nashville, first time at SUSECON and for the most part, first time meeting employees and partners I’ve spoken to but never met yet in person. I had high hopes for a positive outcome and that’s exactly what I received, including a new love for the company I am proud to say I work for. And here’s why…

We just came back from our annual conference SUSECON and the next big SUSE event is just around the corner: SAPPHIRE NOW and ASUG Annual Conference 2019.

SAP Change Management Outcomes – why should you care?

SAP IT teams are under increasing pressure to deal with faster change cycles and higher change volumes to keep pace in today’s digital economy. To adapt, organizations need to transform their SAP change management processes to achieve better business outcomes.

Purism at LibrePlanet 2019 – Showcasing the Librem 5 Phone

This year’s edition of LibrePlanet went on so well, we had people stopping by to ask questions before the conference was open for the day.

Purism’s booth was busy, and people were happy to see us. Nearly everyone we talked to had been following our progress, and everyone was excited to see things in-person. We showcased the fourth version of Librem laptops, and made regular demonstrations of both PureBoot on a Librem 13v4 and Librem Key. Above all, we drew a lot of excitement around the in-person viewing of the Librem 5 devkit. So much excitement, we really wanted to write about the commotion caused by the Librem 5 development – and specially about the devkit demonstration – not only among the audience but also within our own team members.

The Librem 5 phone may still be months away from delivery, but the Librem 5 devkit is under very rapid development. Showcasing our progress is something we’re very proud of, so at the first day of LibrePlanet we whet the appetite of audience members by showcasing sub ten-second boot times from powered-off state to unlock-screen… and we also showed off the initial application support of calling, settings, chat/sms, and browser.

SUSECON – Cloud Talkin’

With over 1,000 attendees from 45 different countries, SUSECON was a truly global affair with a uniquely country twist.

Red Hat contributes CRI-O to the Cloud Native Computing Foundation

Today CRI-O, a project started at Red Hat in 2016 to be an Open Container Initiative-based implementation of the Kubernetes Container Runtime Interface, is being contributed to the Cloud Native Computing Foundation (CNCF). This project joins cornerstone containers and Kubernetes projects we’ve been a part of like etcd and others to join a neutral home for stewardship.

This is a step forward for the containers and CRI-O community because it brings the project into the same home as Kubernetes, which benefits users given its close interdependency. CRI-O and Kubernetes follow the same release cycle and deprecation policy.

CRI-O already has a variety of maintainers outside of Red Hat including Intel and SUSE. Red Hat plans to continue participating in developing CRI-O, especially as a part of our enterprise Kubernetes product, Red Hat OpenShift. With our heritage and dedication to open source software and community-driven development, CRI-O can benefit the community even further within CNCF housed next to Kubernetes.

Welcome to the CNCF, CRI-O!

CRI-O, the Open Container Initiative (OCI) implementation of the Kubernetes Container Runtime Interface (CRI), will join the Cloud Native Computing Foundation (CNCF) incubator today. The project provides an alternative container runtime for Kubernetes and was founded back in 2016 (originally known as OCID) with the introduction of the Kubernetes CRI. CRI-O focuses on its first principles of stability and reliability. This has been proven since one and a half year for now and CRI-O synchronizes its releases with Kubernetes to ensure these principles for the future, too. The projects popularity raised over the past years that it is now the best solution to run Kubernetes workloads in a secure fashion. Currently, CRI-O has worldwide 106 contributors and 9 maintainers coming from Intel, Red Hat, and SUSE. SUSE CaaS Platform version 3 provides it as a technology preview, where CRI-O can be chosen during the installation. No further workload changes are needed to switch from Docker or containerd to CRI-O.
