Case Study: Celonis Standardizes Kubernetes Networking Across 150+ Clusters with CNCF Cilium

Celonis standardizes networking across 150+ Kubernetes clusters with Cloud Native Computing Foundation

Celonis, a global leader in process intelligence, faced a significant challenge with its fragmented networking infrastructure across over 150 Kubernetes clusters on AWS, Azure, and GCP. This complexity, involving six different CNIs and multiple mTLS implementations, created a high engineering tax, blocked upgrades, and slowed down their entire platform. To modernize its stack, Celonis partnered with the Cloud Native Computing Foundation's project, Cilium.

By standardizing on the Cloud Native Computing Foundation's Cilium, Celonis implemented a single operational model for networking, security, and observability across all its clouds. The results eliminated context-switching for engineers, provided more precise FQDN and L7 security policies, enabled default WireGuard encryption for compliance, and gave teams critical network visibility through Hubble, all without any customer downtime during the migration.
