Monthly Snap May

May at NETWAYS was above all the month of the OSDC, but our team still found the time to share some news and thoughts with us all!

It all started with development…

Alexander started the month with his Blogpost Generics waren gestern. Lang lebe Golangs Reflection! And he raises the question if we really need Generics, or if Golangs would do too.
Jean wrote that it all started with a Gameboy and let us take a peek at her personal journey into programming.
Digging up hidden information for a scavenger hunt? Feu reflected on the thrill in geocaching, solving puzzles and hidden riddles.
Noah got technical! How to: Merge multiple Git repositories into one

Live from the OSDC!

Michael shared the latest news live from Berlin: OSDC 2019: Buzzwo…erm…DevOps, Agile & YAML programmers
And so did Tim: OSDC 2019 Part 2 – Automating patching, VMs in containers & much more

News from the NETWAYS shop!

Immer im Takt bleiben – mit Gude. As Nicole informed us, it is possible to synchronize the inbuilt clock in your hardware per GPS!
TinkerForge is still new in the NETWAYS shop, and in May Nicole presented a new Check-Plugin for TinkerForge Hardware.
Nicole also proudly announced that SMS Eagle sponsored the OSDC for the first time! Welcome SMS Eagle!

Spectacular lottery!

Did you know that our NWS team decided to hold a little competition with several great prices? The first price was winning our very own CEO Bernd Erk for a whole day! Read all about it in Marius` blogpost NETWAYS Web Services Raffle

Poetic and philosophical consultants!

Thomas once again showed his poetic skills in a fun rhyme on Icinga. This is definitely worth the read! Irgendwer muss es halt machen!
Gedanken tanken is Tobias idea of feeding the brain useful but also entertaining Input.
Our apprentice Tobias went on his first business trip! Meine erste Reise bei NETWAYS! He held an Icinga advanced training with Lennart in Munich. Meanwhile Afeef, another junior consultant, dove deep into comparing Podman vs Docker.
Viel hilft viel- nicht immer, Thomas claims! He used Elasticsearch to monitor thresholds in Java and shared useful tips with the community.

Just fit- just awesome!

Healthy living (or at least a bit healthier) is still an important subject at the NETWAYS HQ. Nadja gave us tips on how to treat your back well Just fit – just awesome: Rückenschule How should we sit? What exercises can easily be carried out while seated in front of the PC? Many helpful tips in this one!
Then Catharina gave a summary on the first ever NETWAYS Wellbeing day! A day packed with healthy recipes, business yoga and other interesting components that helped us heighten our awareness and to lock out the world for a moment.

What`s next?

Julia invited us to the Foreman birthday party taking place here in Nuremberg on July 25! Read all about it and register for a great program. It is all for free! New and Next in Automation: Notes on OSCamp Berlin! Julia reviewed the OSCamp and reminded us of the next one on Foreman. It will take place in Nuremberg on November 7, right after the OSMC! The highlight in May was definitely the OSDC in Berlin. Julia reported about a terrific conference with a great atmosphere. OSDC 2019: Unique views and phenomenal people. And soon afterwards the OSDC Archive was online!

And the others?

OSDC 2019: Unique views and phenomenal people

When you entered the big, luminous lobby at MOA Hotel Berlin your eyes catched it right away: OSDC‘s pink counter. Behind it either Markus or Lukas from the NETWAYS Events Team welcoming you to the conference, always ready to answer your hardest questions on rooms, rumors, food and all you need to know at OSDC. Thanks to these two guys we‘ve had the pleasure to enjoy a phenomenal conference!

What we’ve done

We‘ve heard tons of entertaining and informative technical talks. We‘ve exchanged thoughts and ideas. We’ve watched demos and fireworks. We got new stickers, job opportunities and insights into our business partners’ stacks, workflows and findings. Not to forget about meeting old pals and making new friends.

Want to know about the talks? Read Michi‘s and Tim‘s blogposts “OSDC 2019: Buzzwo…erm…DevOps, Agile & YAML programmers” and “OSDC 2019 Part 2 – Automating partching, VMs in containers & much more

Inbetween the two-day program Markus and Lukas placed a special treat. What would Berlin be without the Spree? Locals and tourists love its urban flair. And that we enjoyed in one of the best possible ways: on board of the restaurant ship Patio. We‘ve had sundowner drinks on deck, followed by delicious dinner and drinks combined with a unique view and the feeling of being on the water. Can you imagine a better place to socialize?

Thanks to all people – speakers and attendees – who made OSDC special! We are also thankful to our sponsors Thomas Krenn, SMSEagle, Linux Magazin and Admin Magazine for their support and all the NETWAYers for making it happen. See you in 2020, June 17 – 18! Save the date!

Stay tuned for the OSDC archive with all videos, slides and photos!

OSDC 2019 Part 2 – Automating patching, VMs in containers & much more

After having a really successful and sublime evening event on Tuesday, today was the last day of the Open Source Data Center Conference.

Andreas Lehr and Rico Spiesberger showed off with their automated patch management using Ansible and Rundeck at Lidl and Kaufland.
Things to keep in mind:

  • rebooting bare metal takes time
  • firmware updates might change things
  • have enough space in /var/yum and /tmp -> might result in kernel panics (:

And why not doing a Live Demo at a production system and simply patch the spanish webshop?

On the next slot, it was our pleasure to welcome Kosisochukwu Anyanwu with kinvolk.io. She showed us how to use KVM as a Hypervisor, running a VM in a Docker Container! Get in touch with her at @kosyfrances and feel free to ask her for their use case.

Nikhil Kathole presented how to simplify your IT Workflow with Katello and Foreman. You can use Foreman for provisioning, configuration and monitoring (to some extend) of your hosts. It also provides you with many plugins for flexibility for provisioning tools and infrastructure. If you want to manage your .rpms/.debs, katello should be your choice

 

Troy Harvey started with tossing shirts and gave a quite interesting introduction into the concept of privacy. Privacy demands ethical behaviour of professionals and they should always try to automate things

 

Furthermore, if you want to have to use slack, try to get a job at Carta.

Colin Charles closed the conference with mysql & mariadb security. Obviously breaches are bad and there are the issues you can easily avoid. Use TLS for replication – also update your instances!

I don’t know how you feel after these two days. But I feel like I want more of that! Save the date for next OSDC!

OSDC 2019: Buzzwo…erm…DevOps, Agile & YAML programmers

OSDC 2019: Buzzwo…erm…DevOps, Agile & YAML programmers

Cheers from Berlin, Moabit, 11th round for OSDC keeping you in the loop with everything with and around DevOps, Kubernetes, log event management, config management, … and obviously magnificent food and enjoyable get-together.

 

Goooood mooooorning, Berlin!

DevOps neither is the question, nor the answer … Arnold Bechtoldt from inovex kicked off OSDC with a provocative talk title. After diving through several problems and scenarios in common environments, we learned to fail often and fail hard, and improve upon. DevOps really is a culture, and not a job title. Also funny – the CV driven development, or when you propose a tool to prepare for the next job 🙂 One key thing I’ve learned – everyone gets the SAME permissions, which is kind of hard with the learned admin philosophy. Well, and obviously we are YAML programmers now … wait … oh, that’s truly inspired by Mr. Buytaert, isn’t it? 😉

Next up, Nicolas Frankel took us on a journey into logs and scaling at Exoscale. Being not the only developer in the room, he showed off that debug logging with computed results actually eats a lot of resources. Passing the handles/pointers to lazy log function is key here, that reminds me of rewriting the logging backend for Icinga 2 😉 Digging deeper, he showed a UML diagram with the log flow – filebeat collects logs, logstash parses the logs into JSON and Elasticsearch stores that. If you want to go fast, you don’t care about the schema and let ES do the work. Running a query then will be slow, not really matching the best index then – lesson learned. To conclude with, we’ve learned that filebeat actually can parse the log events into JSON already, so if you don’t need advanced filtering, remove Logstash from your log event stream for better performance.

Right before the magnificent lunch, Dan Barker being a chief architect at RSA Security for the Archer platform shared stories from normal production environments to actually following the DevOps spirit. Or, to avoid these hard buzzwords, just like “agile”, and to quote “A former colleague told me: ‘I’ve now understood agile – it’s like waterfall but with shorter steps.'”. He’s also told about important things – you’re not alone, praise your team members publicly.

 

Something new at OSDC: Ignites

Ignite time after lunch – Werner Fischer challenged himself with a few seconds per slide explaining microcode debugging to the audience, while Time Meusel shared their awesome work within the Puppet community with logs of automation involved (modulesync, etc) at Voxpupuli. Dan Barker really talked fast about monitoring best practices, whereas one shouldn’t put metrics into log aggregation tools and use real business metrics.

 

The new hot shit

Demo time – James “purpleidea” Shubin showed the latest developments on mgmt configuration, including the DSL similar to Puppet. Seeing the realtime changes and detecting combined with dynamic processing of e.g. setting the CPU counts really looks promising. Also the sound exaggeration tests with the audience where just awesome. James not only needs hackers, docs writers, testers, but also sponsors for more awesome resource types and data collectors (similar to Puppet facts).

Our Achim “AL” Ledermüller shared the war stories on our storage system, ranging from commercial netApp to GlusterFS (“no one uses that in production”) up until the final destination with Ceph. Addictive story with Tim mimicking the customer asking why the clusterfuck happened again 😉

Kedar Bidarkar from Red Hat told us more about KubeVirt which extends the custom resource definitions available from k8s with the VM type. There are several components involved: operator, api, handler, launcher in order to actually run a virtual machine. If I understand that correctly, this combines Kubernetes and Libvirt to launch real VMs instead of containers – sounds interesting and complicated in the same sentence.

Kubernetes operators the easy way – Matt Jarvis from Mesosphere introduced Kudo today. Creating native Kubernetes operators can become really complex, as you need to know a lot about the internals of k8s. Kudo aims to simplify creating such operators with a universal declarative operator configured via YAML.

 

Oh, they have food too!

The many coffee breaks with delicious Käsekuchen (or: Kaiser Torte ;)) also invite to visit our sponsor booths too. Keep an eye on the peeps from Thomas-Krenn AG, they have #drageekeksi from Austria with them. We’re now off for the evening event at the Spree river, chatting about the things learnt thus far with a G&T or a beer 🙂

PS: Follow the #osdc stream and NetwaysEvents on Twitter for more, and join us next year!

Monthly Snap April 2019

Springtime in Nuremberg! In this month of Easter-eggs and chocolate bunnies our colleagues wrote about various interesting subjects. You missed some of these? Just click the links below!

No Aprils fools at NETWAYS!

Nicole started the month with a post from the NETWAYS shop on the Expert Sensor Box von GUDE, with which you can monitor your infrastructure. Alerts are sent by E-Mail if the temperature, the humidity or the air pressure deviates from your set limits.
A week later Nicole presented the Expert Net Control von Gude. A bigger monitoring system which can also monitor water leaks and detect smoke.
The summer can really cause damage to your data center. Rising temperatures and higher humidity need to be reined in. Nicole explained how the NETWAYS Monitor alerts you if needed in her blog Der Sommer kommt!
Our apprentice Tobias visited our shop for a week and had a look at some of our products. In his blogpost Und der Sommer kommt immer noch! he presented the Ares 12 von HW group, with which you can monitor not only the usual temperature and humidity, but among others also wind strength! Last month Henrik wrote about testing Tinkerforge. Now Nicole offers it in the NETWAYS Shop: RackMonitoring Kits von TinkerForge!
