The long awaited OpenStack UK day took place on the 26th of September in London. Component Soft participated in the event, as Gold level Sponsors, so we’d set up a booth to meet and greet and we also presented on 2 different topics regarding OpenStack.
A summary of the day’s events
Our first presentation – by Csaba, our OpenStack specialist – was about using Elastic stack for logging and Prometheus for monitoring your OpenStack.
Prometheus is a new monitoring tool specifically designed for cloud technologies like Kubernetes, Docker, and now OpenStack.
His slides are available here. We will update this post with the video recording as soon as it is available.
These tools provide a handy way to monitor and log your OpenStack’s activity, helping with troubleshooting efforts.
Csaba even put together code for a test environment, that you can access here.
While Csaba was busy illuminating the attendees on his monitoring mojo, I was outside in the lobby, providing information about our various OpenStack and Open Cloud trainings. Interestingly we were the only dedicated training company sponsoring the event. Shoutout to our booth-neighbours, NGINX for the T-Shirts.
Our second presentation was a group effort. It was about the various official exams attached to Open Cloud technologies, like OpenStack’s Certified OpenStack Administrator, and the upcoming Certified Kubernetes Administrator exams. You can access the slides here.
The first part was about the market value of these exams, as presented by Erno, our CEO. These exams seem to be increasing in value and demand, both for Open Cloud professionals in the job market, as well as companies working with these technologies, to show they have the experts to help their clients.
In the second half of the presentation our instructors, Csaba and Agoston shared practical advice for these exams. Csaba is a Certified OpenStack Administrator, and he is the brain behind our 10 tips for better chances for the COA exam. Agoston had been participating in the beta test for the Certified Kubernetes Administrator exam over the summer. The exam itself only released a few days before the conference.
The conference was an amazing experience, and we are glad to have contributed our expertise to this gathering of OpenStack professionals. If you weren’t able to come, I hope you can next year!

OpenStack has evolved into a complex “Cloud Operating System” for datacenters with a lot of moving parts. Operators must be able to monitor, measure and troubleshoot OpenStack but that is not a trivial task.
In this presentation, originally recorded at the OpenStack CEE day 2017 in Budapest our instructor and consultant, Csaba Patyi talks about current solutions and practices and show what might be the future.

The OpenStack Foundation have officially switched the COA exam to the new version of OpenStack: Newton. This change, along with several usability improvements to the exam itself (for example you can navigate between questions freely from now on), has been in the making for some time. In anticipation of this change we have been working tirelessly these past months and are proud to announce that we have successfully switched our courseware to Newton as well. Our OST-104 OpenStack Admin and COA prep. course prepares you for the new requirements of the COA exam.
Here’s the announcement video:

Near the end of last year OpenStack.org asked us to provide practical tips about taking the Certified OpenStack Administrator exam, for their article collecting the tips of various training centers. In this post we attempt to expand on our advice shown in the OpenStack.org article.
They are quite well documented. Familiarizing yourself with the requirements helps you prepare more efficiently for the exam.
2. Be sure to have a fast and reliable internet connection for the exam
as not only Linux commands but also the Horizon GUI and you web cam and the background monitoring of your machine use valuable bandwidth as well.
3. You need an empty room for the exam with you as the only person in it.
The proctor will check it before you start the exam.
4. Allow yourself enough time for hands-on exercises with all the OpenStack topics in the OpenStack COA Requirements.
Participants of our OST-104: Openstack Admin. and COA exam prep. training can do these exercises not only during the course but will also receive one week extra remote lab access after the training by request.
5. You should know both the OpenStack commands and the Horizon admin tool to achieve good results.
Knowing the command line is practically a must.
6. Be prepared that you can only use the US English keyboard layout during the exam!
As Component Soft has course participants from all over the world, we have heard from some of our participants that using the US keyboard layout was jarring and unusual which slowed them down. If you use another layout, make sure you practice using the US one before the course.
7. The Linux screen command is very useful to split your single command terminal during the exam.
This way you can improve your productivity, especially in more complicated exercises.
8. You can only set Swift advanced ACL settings in the command line, not in Horizon.
9. Be careful to use the proper user, project and domain names given in each exercise!
10. Participate in a preparatory course
As referenced above, we offer a comprehensive course aimed at equipping you with the knowledge necessary for an OpenStack administrator as well as preparing you for the COA exam, complete with Lab exercises and more, in-depth advice.
For a More deatailed look at some of these tips, and a dive into the Cinder part of the exam, check out my tutorial video below:

Last week my colleagues and I had the opportunity to attend the 2017 CloudNativeCon + KubeCon in Berlin. The journey was quite enlightening. Although we listened to several talks about the future of Cloud Native technologies, for me, the most interesting part was that the present of Kubernetes already looks quite bright. From the numerous talks, I wanted to share the two case studies that I think represents this the most.
One of the case studies presented the now-infamous shut-down of Amazon’s S3 server. The shutdown affected countless services that rely on its advertised high availability. The speaker, with some satisfaction, announced, that due to the automated management capabilities of Kubernetes, companies that used the fledgling open-source service remained available through the incident. They simply watched Kubernetes switch hosts while the rest of the internet was melting down in panic.
Another case study of interest was that of Magazine Luiza, a Brazilian retail company, that recently adopted Kubernetes. This adoption was particularly useful during Black Friday, when traffic to online stores increases exponentially. The company has a history of shaving off more and more downtime during the traffic rush on Black Friday. However, in previous years they were unable to produce 100% availability, which is crucial, as on Black Friday every second of downtime means significant revenue losses. In the preparation to the 2016 event, they decided to give Kubernetes a try. While deploying the apps they even developed an open source deployment tool. Mr Pereira, the representative of Luiza Labs, speaking at the event, proudly announced that in 2016 Black Friday went smoothly, without any interruptions in service.
As these case studies show, Kubernetes as a technology, although still in its early stages, is already making strides in transforming the limits of highly available services. It exceeds the human restrictions that prevented swift reactions to spikes in traffic or unexpected resource-outages. The automated deployment and scaling it provides seems to have significant potential, and we have seen already what it can do.
