From Hours To Minutes: The Evolution of Platform Engineering at Decathlon
Talkat KubeCon + CloudNativeCon Europe 2025 · on Thursday, 2025-04-03· at 16:45· Level 1 | Hall Entrance N10 | Room F·
summary
Decathlon scales a platform for 5,000 users that delivers 20 minutes to provision environments by running YAML descriptors and Terraform under the hood to create GCP projects; a 15-person core team and 50+ contributors build the 3S self-service stack and later SRP/MRP variants plus a Terraform provider and the Platform PFC API for internal connectivity. Adoption stalls because SRP/MRP break seamless migration, tests and Terraform runs hit performance limits, so the choice is made to revert and backport features while improving release management and developer UX.
