Kubernetes at DH: A journey from YAML headaches to Helm bliss

You must have been living under a rock if you haven’t heard the Kubernetes (k8s) hype over the last few years. It has quickly become the platform of choice for running applications for many modern tech companies and Delivery Hero is one of them. What is unique about DH, is that some of our tech teams are very isolated, sometimes even on different continents, speaking different languages, with different applications trying to solve different problems.

Dynamically overscaling a Kubernetes cluster with cluster-autoscaler and Pod Priority

My name is Miguel Angel Mingorance Fernandez and I’m a Systems Engineer at Delivery Hero, working to ensure high availability in our foodora/foodpanda platform and providing solutions to improve the performance, capacity and resilience of our infrastructure.

Kubernetes is a very flexible system but not perfect. When it comes to cluster scaling, the delays in spinning up new nodes can create latency in dealing with the increase of requests that triggered the scaling, causing a negative feedback because we can’t handle the traffic quickly enough.

My experience from the Domain-Driven Design Europe 2019 conference

My name is Kostas Stroggylos and I am a Senior Software Engineer, acting as the tech lead for the team building the Restaurants and Internal Tools at e-food. During the last week of January I had the pleasure of attending the Domain-Driven Design Europe 2019 conference in Amsterdam. It was two exciting days filled with exchanging ideas with practitioners and fellow meetup organizers from all over the world, drawing models with strangers, trying to uncover DDD Borat’s identity, taking sketchnotes and using a lot of post-it notes. Now that the excitement has settled, I want to share some of the highlights and takeaways from this event.
