Blue-Green Deployments Using Heptio Ark

Heptio Ark is a tool used for taking backups of a running Kubernetes cluster. At HelloFresh, we've used it for performing a blue-green deployment on our production Kubernetes cluster. In this talk, we will do a quick introduction to Heptio Ark, and discuss how it helped us change networking infrastructure on our production Kubernetes cluster without incurring any downtime.

7:30 - 8:00p - ArangoDB - Max Neunhöffer

Developing a DevOps Friendly K8s Integration for ArangoDB

ArangoDB is a scalable, distributed multi-model database. However, for this talk, it is not necessary to know what this means. Rather the only crucial fact is that it is distributed and written in C++.

In recent months we’ve received many requests to support Kubernetes “out of the box”.

This talk is about an ongoing journey from early yaml files to an advanced integration supporting scaling, upgrading and monitoring in a DevOps friendly way.

The journey will take us from tiny cloud environments to bespoke hardware, touching subjects such as persistency performance, session stickiness, access control and federation.

Our journey has not reached its destination yet, but the destination looks promising and the journey so far has been an interesting one, that we will happily share with you.

8:00 - 8:35p - Wrap-up, head out.

Max Neunhöffer is a mathematician turned database developer. In his academic career he has worked for 16 years on the development and implementation of new algorithms in computer algebra. During this time he has juggled a lot with mathematical big data like group orbits containing trillions of points. Recently he has returned from St. Andrews to Germany, has shifted his focus to NoSQL databases, and now helps to develop ArangoDB. He has spoken at international conferences including O’Reilly Software Architecture London, J On The Beach or MesosCon Seattle.
