Operator pattern

Glossary Page

The Operator pattern is a design approach that connects one or more custom resources to a Controller. With Kubernetes, you can expand the built-in controllers by introducing new ones to your cluster. An instance of the Operator pattern is when a running application functions as a controller and has API access to perform actions against a custom resource that has been defined in the control plane. By doing so, the Operator pattern can automate complex, application-specific tasks within the Kubernetes environment.

Bundesliga fans on the move: What Motion Data reveals about football culture

The article explores how T‑Systems’ Motion Data leverages anonymized mobile network information to reveal real‑world fan behavior in the 2024/25 Bundesliga season. It highlights how supporters travel to home and away matches, the demographic composition of stadium audiences, and which clubs attract the largest crowds—including surprising cross‑border dynamics. By transforming assumptions into measurable insights, Motion Data enables clubs, cities, and event organizers to improve mobility planning, enhance stadium operations, and design more targeted fan engagement strategies.

Sovereign connectivity: Automating access in dataspaces

Sovereign connectivity in dataspaces requires automating network access to ensure security, compliance, and operational scale. In the Data Intelligence Hub, we replace manual firewall updates with a declarative, Kubernetes-native model using Custom Resource Definitions (CRDs). Customers define their allowed IP ranges through a self-service portal, which generates an IpAccessPolicy object representing the desired state. A controller then reconciles this state with the underlying infrastructure, automatically updating Kubernetes Ingress configurations and preventing drift. This architecture ensures auditability, validates inputs before enforcement, and keeps network access aligned with the principles of data sovereignty across multi-tenant environments.
