Why This Mattered. Next-generation telecom services can’t tolerate downtime or latency — the platform running them has to be resilient and scalable enough to carry live, tier-1 network traffic while it’s being rebuilt underneath. That was the challenge here: deploy a new container platform capable of running Cloud-Native Network Functions (CNFs) and Virtualized Network Functions (VNFs) under strict telco-grade service level agreements, without interrupting the services already running.

What We Did. Centos Digital deployed the core Red Hat OpenShift infrastructure — a mix of bare-metal and virtualized environments — using a GitOps approach built on Argo CD, Ansible, and Terraform, so every change to the environment was version-controlled and repeatable rather than manual and undocumented.

From there, we onboarded some of the highest-risk network functions in the stack, including ePDG and DRA, one at a time — testing and tuning network routing and pod placement on RHEL Linux before each went live, so nothing reached production without being verified first. Alongside the new platform build, we kept the client’s existing OpenStack environment stable, providing ongoing system administration and performance tuning so day-to-day operations weren’t disrupted by the migration happening around them.

The Result. The new platform went live with zero downtime during the onboarding of its most sensitive network functions — no small thing for infrastructure carrying live telecom traffic. The GitOps-based deployment approach also paid off structurally: new network functions that used to take significant manual effort to deploy now roll out over 40% faster, because the process is declarative and repeatable rather than rebuilt by hand each time.
