Case Study: Tietoevry reduces Kubernetes tool sprawl with Isovalent Cilium

Reducing Kubernetes tool sprawl Tietoevry uses Cilium and Hubble

Tietoevry Industries, a provider of segment-specific software and data platform services, needed a way to secure and connect Kubernetes clusters across VMware Cloud Director, Azure Kubernetes Service, and bare metal environments. The team was struggling with Kubernetes tool sprawl, cumbersome IP-based policies for external services, limited network observability, and the need to support a zero-trust model while helping app owners troubleshoot more independently.

Using Isovalent Enterprise for Cilium, Tietoevry consolidated networking, security, and observability into one platform with Cilium and Hubble. Isovalent helped the company implement DNS/FQDN-based policies, zero-trust controls, self-service troubleshooting, and richer traffic visibility, while reducing the need for extra tools like an ingress controller or service mesh. The result was simpler Kubernetes operations, better observability, and faster modernization of legacy apps, with the team estimating that Cilium on one legacy application saved roughly a year of work.
