\u201cClose your eyes, give me your hand, darling.<\/span><\/i><\/p>\n

Do you feel my heart beating?<\/span><\/i><\/p>\n

Do you understand?<\/span><\/i><\/p>\n

Do you feel the same?<\/span><\/i><\/p>\n

Am I only dreaming<\/span><\/i><\/p>\n

Is this burning an eternal flame!\u201d<\/span><\/i><\/p>\n

The last day of the great gathering started. For some it was an early start, but they would rather die than miss that fantastic event.<\/span><\/p>\n

The first talk \u201cContinuous Database Integration with Flyway<\/strong>\u201d by Sandra Parsick was canceled because Sandra was ill. So Peter Rossbach organized several lightning talks instead. Some of them were a good addition to the conference, for example the talk of Andreas Burbach about how to transform a big traditional business to use a modern flexible infrastructure. This should be done in small steps. He demonstrated it on an example he experienced with the introduction of flyway to such a company.<\/p>\n

\"20180221_091506.jpg\"Quite interesting was the short talk \u201c<\/span>Hardening software <\/strong>development<\/strong>\u201d by Thomas Weidinger, which drawed a lot attention to <\/span>the audience. There were shown many <\/span>examples of how easy an <\/span>infrastructure code can be hacked or manipulated with malice and how developers can prevent that.<\/span><\/p>\n

One talk was completely off topic, but a good distraction raising the mood. It was \u201cHow to grow chilli peppers\u201d<\/strong>. Literally. It turned out that it is a big science about planting the seeds into a camomile tea and having a special recipe for the soil later on.<\/p>\n

After a coffee break full of networking, the serious talks started. The first was \u201cDeploying and Managing Productiongrade Kubernetes Clusters with Rancher<\/strong>\u201d by Jan Bruder from Rancher. Rancher is the <\/span>next abstraction and management level for Kubernetes managing <\/span>virtual machines and containers. The open source software tries to improve the fact that running containers in production is still not easy because there are many different tools working together. They give a <\/span>big promise to \u201cbuild a complete container deployment within five minutes\u201d. Rancher uses its own container orchestration framework called cattle. And you can start immediately by typing \u201cdocker run -d -p 8080:8080 rancher\/server:stable\u201d in your terminal. This will run a rancher server on your local system.<\/span><\/p>\n

The next talk \u201c<\/span>Modern Monitoring for Dev and Ops<\/strong>\u201d by Bj\u00f6rn Rabenstein from SoundCloud was about modern monitoring principles. He showed the difference between blackbox- and whitebox monitoring. Blackbox monitoring is the traditional way to monitor a system. The monitoring system does not know which system it is supervising. It only checks the output of it. There is one big disadvantage of this purpose: for not yet occurred but imminent problems black-box monitoring is fairly useless. There are three reasons why black-box monitoring is not sufficient in other cases:<\/span><\/p>\n
