Recap OpenStack Summit Berlin 2018

This review falls back in the year 2015, my first visit of an OpenStack Summit in Tokyo.

I recognized how cool would be to have a OpenStack Summit in Germany, especially in Berlin area, where I live.
Just around this time (2015/2016) the OpenStack Foundations sent out a Call for Venue, so I proposed Berlin ICC as the convention area.
Unfortunatelly that building was closed and Messe Berlin starts with construction of the CityCube. Now, in 2018, the OpenStack Summit is gone, just 2 days before as the last OpenStack Summit which will we ever haved. The OpenInfrastructure Summit was born here and the first one will be held in Denver (US) April/May 2019.

DevOps - mehr als ein moderner Buzzword Krimi

Posted by on 16 Jul 2018 in inet, cloud-computing

Mein letzter Blogartikel zum Thema DevOps ist jetzt ueber 6 Jahre her. Damals gings noch um Schatten-IT und dem steten Grabenkampf zwischen Entwicklung und Betrieb. Mittlerweile bin ich selt einiger Zeit Mitglied in einem DevOps-Team, was ein Paradoxum an sich ist, denn sowas wie DevOps-Teams gibt es gar nicht. Stattdessen geht es um den Flow.

Wie organisiere ich einen Hackathon

Posted by on 05 Feb 2018 in general

Wikipedia schreibt: Ein Hackathon (Wortschöpfung aus „Hack“ und „Marathon“) ist eine kollaborative Software- und Hardwareentwicklungsveranstaltung. [...]  Ziel eines Hackathons ist es, innerhalb der Dauer dieser Veranstaltung gemeinsam nützliche, kreative oder unterhaltsame Softwareprodukte herzustellen.

 

Wie geht sowas?

Ansible-OTC 2018

Posted by on 03 Jan 2018 in cloud-computing, ansible

After another year with work and usage of Ansible-OTC I want to share a project update and the vision for 2018.

 

  1. Role collection. There are a lots of roles in the Github Repo. This is good to show the work of OTC-API and for demonstration, but bad for overview and automation. I tried to collect functions following the CRUD standard into new roles. I.e. otc_ecs should Create, Read, Update, and Delete ECS resources on OTC: https://github.com/eumel8/ansible-otc/tree/dev/roles/otc_ecs
  2. Input-Handler. It was a good idea to use ini-files for configuration items, because it's good readable and easy to unterstand. Previously I used yml-files for the same function, other projects are using json.  To split this function more from the Ansible roles I created different handlers for ini, yml and json, so the customer can choice: https://github.com/eumel8/ansible-otc/tree/dev/playbooks/vars
  3. Testing. Ansible developement goes really fast, so code can sometimes break because things aren't working anymore in newer versions of Ansible or Python. I started to play with Travis and included some functional tests: https://travis-ci.org/eumel8/ansible-otc
  4. Documentation. There are multiple Markdown files for use cases and role description. I switched to Sphinx, which is more portable and documentation is nearly to the code like the role documentation. A published version is on http://ansible-otc.readthedocs.io/en/dev/?badge=latest

 

As you can see the next release of Ansible-OTC will contain a lot of changes, so it will be easier to use OTC with Ansible.

 

What's up OpenStack Summit Sydney

Posted by on 06 Nov 2017 in cloud-computing, openstack

Just another OpenStack Summit is started yesterday. It's one of the smaller events because it's far away in Australia ("only" 2300 attendees are registered), but 55% comes from APAC and if you imagine that 12 from 24 Gold Sponsors are coming from China then you can see how important is this area. The newest Gold Member and winner of the Super User Awards is Tencent Cloud.

People from 55 countries are together and Germany is already in the top 10.

What's new in OpenStack Community:

  1. Open Infrastructure Integration. Users of OpenStack interacting more and more within other projects beside OpenStack. The Foundation will pay attention on this fact and support collaboration with other communities and projects. At least the "BigTent" is going away, this was the idea to collect OpenStack core projects, but divided this to others.
  2. OpenLab Initiative. The user experience in multi-cloud and application frameworks should be improved. Among others Huawei and Open Telekom Cloud will pay attention on this topic
  3. Public Cloud Passport Program. The count of OpenStack deployments  increased tremendously in the last months (following OpenStack User Survey +95% to 2016). Promoting this and start with collaboration is the goal of the Passport Program
  4. Financial Services is one of the newcomer in OpenStack Services. Check out the Lessons Learned session
  5. Contributor Portal. The idea starts at the PTG in Denver to invent a new landing page for contributors.
  6. Multi-Cloud/Edge-Computing are the next big things. Regarding the user survey nearly 48 % of the OpenStack user are interacting also with other clouds. 87 % believe that OpenStack is the right tool for Edge Computing

 OpenStack is all about community. There are four steps for OpenSource integration:

  1. Find the common use case
  2. Collaborate across communities
  3. Build the required new technology
  4. Test everything end to end

This end-to-end responsibilty is really new. I believe this will change in the OpenStack community in the near future and a lot's of new projects will come in to have a share with the open-minded people and the experience of the last 7 years.

Open Telekom Cloud - Connect Cheat Sheet

Posted by on 11 Jun 2017 in cloud-computing, openstack

Open Telekom Cloud (OTC) is a public cloud service based on OpenStack powered by Deutsche Telekom. [1]
Sometimes people ask: is it OpenStack? Or not? The answer is: Of course,yes. No. Maybe. I'm afraid.
One thing is certain: #OTC #RunsOnOpenstack
Technology is provided by Huawei, one of the Top 4 contributor in OpenStack [2]. So you have core technology with slightly different services in OTC. Now there are different ways to connect to the cloud:
