Shopify's Path to k8s

Presented a talk on building a platform as a service on top of Kubernetes and Google Kubernetes Engine. The goal was to share Shopify's best practices and start a discussion in the community to see how others are tackling similar challenges.

How we did it: One customer’s journey to modern infrastructure

Co-presented a session on the experiences of using containers and Kubernetes in production and lessons to keep in mind when undertaking such a migration.

Building Containers @ Shopify

Gave a talk on container building at Shopify and the tooling we used and built. The goal was to share our experiences and promote best practices across the local community.
