What is the Control Plane?
The Control Plane is the central management layer for the Open Telekom Integration Platform, governing Kubernetes cluster operations. It maintains the system's desired state, manages workloads, and provides user interaction interfaces.
⚙️ Operators
Specialized control loops managing complex domain-specific applications and configurations using the Kubernetes Operator pattern.
🔌 API Servers
RESTful APIs for managing Kubernetes custom resources, providing a standardized interface for platform interaction.
📚 Libraries
Shared code modules between different projects to ensure consistency, reduce duplication, and accelerate development.
