Your Philips Hue Light Bulbs Are Turned On By Kubernetes

Philips Hue is one of the leading global Internet of Things platforms and has integrations with Amazon Echo, Google Home, IFTTT & Nest to make your lights work for you. The platform has grown considerably during the past years and to accommodate this has been migrated towards Google Container Engine (Kubernetes) at the end of 2015.

We needed to find out how to do zero downtime deployments, grasp how scaling works in Kubernetes, provide ourselves with monitoring and logging and above all find out how to do all these things and more while staying agile in the process. Grab something to drink and enjoy a deep dive into all the things we have encountered while running on Kubernetes.

Canary releasing: not a free lunch, but still a very tasty one!

Canary releasing is a variant of blue-green releasing that offers a lot of cool possibilities in the areas of avoiding performance issues, testing in production and generally providing a more controlled and safe way of deliver software upgrades. But of course nothing is ever for free, and to successfully apply canary-releasing to your deployment pipeline there are several requirements that need to be in place and design-decisions that need to be answered.
With our experiences in developing and applying Vamp we’ve learned about these requirements and designs. In this talk we are going to zoom in on what it takes to move into canary-releasing territory.

He has a CS background and has over 15 years of experience in the online industry in various technical and managerial roles.
