# Components

Bindplane Server relies on several key components when deployed on Kubernetes:

## Core Components

### [Event Bus](/deployment/kubernetes/server/components/event-bus.md)

NATS provides the messaging backbone for Bindplane, enabling reliable communication between server instances and collectors. It handles configuration updates, heartbeats, and telemetry routing.

### [Kubernetes Ingress](/deployment/kubernetes/server/components/kubernetes-ingress.md)

The Ingress controller manages external access to Bindplane services, providing TLS termination, load balancing, and routing capabilities for both the UI and API endpoints.

### [PostgreSQL](/deployment/kubernetes/server/components/postgresql.md)

PostgreSQL serves as the primary stateful storage for Bindplane, maintaining configuration data, collector registrations, user information, and audit logs in a reliable and scalable database.

These components work together to provide a resilient, scalable platform for managing your telemetry pipeline. Each can be configured and scaled independently to meet your specific requirements.
