Catalyst hosting
Diagrid Catalyst is built on the open-source Dapr runtime and centralizes the Dapr deployment in a Kubernetes cluster — operated by Diagrid or by you — where it runs as a managed platform. Your applications connect to the Catalyst data plane, which handles workflow execution, state management, and distributed-application coordination, independently of where those applications run.
Hosting options
Catalyst offers multiple hosting options, from a fully managed cloud service to a fully air-gapped deployment. They differ in who operates the control plane and the data plane:
| Plan | Hosting option | Control plane | Data plane | Description |
|---|---|---|---|---|
| Catalyst Cloud | Multi-tenant | Diagrid | Diagrid | Shared infrastructure across all Catalyst Cloud customers. Fastest way to get started with zero setup. |
| Catalyst Enterprise | Dedicated | Diagrid | Diagrid | Diagrid-managed, but the Catalyst data plane runs on a separate Kubernetes cluster provisioned exclusively for the customer. |
| Self-Hosted | Diagrid | Customer | Catalyst control plane managed by Diagrid with the Catalyst data plane running on customer infrastructure for full data residency control. | |
| Air-Gapped | Customer | Customer | Fully offline, network-isolated deployment with no external connectivity. Used for regulated and defense environments. |
Within any option, Catalyst isolates workloads using regions — data-plane clusters — and projects, logical groups within a region.
The diagrams below show where the control plane, the data plane (Dapr deployment plus Catalyst agent), and your applications run in each option.
Catalyst Cloud
A shared, Diagrid-hosted control and data plane. Your applications connect over the public internet. Best for evaluation and small-to-medium development workloads.
Catalyst Enterprise: Dedicated
A dedicated, single-tenant control and data plane managed by Diagrid. The topology mirrors Catalyst Cloud, but the platform is isolated to one customer and sized for production workloads.
Catalyst Enterprise: Self-hosted
Diagrid manages the control plane; the data plane runs inside your infrastructure. Applications connect to the data plane over your private network, keeping application traffic and data local.
Catalyst Enterprise: Air-gapped
Both the control plane and the data plane run inside your infrastructure. No traffic leaves your network, which suits environments with strict regulatory or network isolation requirements.
