Building a platform sounds right until every team builds its own. At one of the world’s largest retailers, one platform didn’t fit all, but many siloed platforms did not scale. Different products, constraints, and experience levels drove divergence.

In this talk, we show how we addressed this by building an Open Source Platform Framework not as a rigid product, but as a shared foundation. It allows teams to own their platforms while sharing common practices, from standard cloud setups to 15,000+ edge locations.

What you will see:

-> Why Kubernetes alone was not enough, even when managed

-> GitOps as the glue between governance and autonomy using a
hub and spoke, multi-tenant model

-> How we integrated CNCF tools instead of reinventing them

-> Lessons learned taking an internal tool toward open source and why inner source was harder than expected

No platform utopia, just honest lessons from building and operating framework in production for multiple platform teams.
