Camunda 8 Self-Managed architecture

Camunda 8 Self-Managed is highly customizable and can be deployed in different setups. Helm/Kubernetes is the recommended method to deploy Camunda 8, especially in production. Our Helm chart provides many capabilities to customize deployment according to your needs. This page provides a high-level overview of the architecture and deployment options.


Camunda 8 Self-Managed has multiple web applications and gRPC services which could be accessed externally using Ingress. The following diagram is the architecture with two Ingress objects, an Ingress with HTTP(S) protocol for all web applications using a single domain, and another Ingress with gRPC protocol for the Zeebe workflow engine:

In this architecture, Camunda 8 Self-Managed can be accessed as follows:

  • Web applications:[identity|operate|optimize|tasklist|modeler]
    • Note: Web Modeler also exposes a WebSocket endpoint on This is only used by the application itself and not supposed to be accessed by users directly.
  • Keycloak authentication:
  • Zeebe gateway: grpc://

It's also possible to set up an Ingress for each component. For more details, visit our combined and separated Ingress setup guide.


Each component of Camunda 8 Self-Managed can be deployed in single or high-availability mode, which provides minimal to no service interruption. The following diagram represents deployment in high-availability mode:

Additional considerations

  • The Kubernetes resources that don't have a custom configuration like Service and ConfigMap are not in the diagram.
  • By default, the deployment requires at least three Kubernetes Nodes to meet the Pod Anti-Affinity constraints.
  • For components with Anti-Affinity enabled, like Zeebe Broker, the Kubernetes Nodes should be equal to or greater than the number of the Pod replicas. Otherwise, some of its Pods will not be scheduled and will be in a "Pending" state.
