# Deployment Architecture

DCE 5.0 offers three deployment architectures: [beginner mode](#beginner-mode), [4-nodes](#4-node-mode), and [7-nodes](#7-node-mode-1--6).

The following table provides an overview of the terms used in the architecture:

| Name | Description  |
| ---- | ------------ |
| Bootstrap Node | The bootstrapping node, also known as the bootstrap node, installs and executes the deployment program. It runs the container registry and chart museum required by the platform. |
| Global Service Cluster| This cluster is responsible for deploying all components of DCE 5.0 and utilizes [Kubean](https://github.com/kubean-io/kubean) to manage the cluster's lifecycle. |
| Workload Cluster | The workload cluster supports business applications and services. It should be deployed after successfully installing DCE. |
| DCE Component | All components of DCE 5.0, including product modules such as global management, container management, observability, Workbench, Multicloud Management, container registry, microservice engine, service mesh, and middleware. |

## Beginner Mode

The beginner mode is suitable for individual customers and requires only one host. However,
it is recommended to use this mode minimally by adding the `-z` parameter after the installation command when installing DCE 5.0.

## 4-Node Mode

The 4-node mode consists of one bootstrapping node and three master nodes within the cluster. It is recommended for PoC or test environments.

## 7-Node Mode (1 + 6)

The 7-node mode includes one bootstrapping node, three master nodes within the cluster, and three worker nodes exclusively dedicated to the Elasticsearch component. This mode is recommended for production environments.
