Multi-Tenant Management

Unified Multi-Tenant Management

FusionInsight Manager is a unified multi-tenant management platform, which integrates multiple functions, such as tenant lifecycle management, tenant resource configuration, and tenant resource usage statistics, delivering a mature multi-tenant management model and achieving centralized tenant and service management.

Graphical User Interface

FusionInsight Manager provides the graphical multi-tenant management interface and manages and operates multiple levels of tenants using the tree structure. Additionally, FusionInsight Manager integrates the basic information and resource quota of the current tenant in one interface to facilitate O&M and management, as shown in Figure 1.

Level-based Tenant Management

FusionInsight Manager supports a level-based tenant management model in which you can add sub-tenants to an existing tenant to re-configure resources. Sub-tenants of level-1 tenants belong to level-2 tenants, and so on. FusionInsight Manager provides enterprises with a field-tested multi-tenant management model, enabling centralized tenant and service management.

Simplified Rights Management

In FusionInsight Manager, common users are shielded from internal rights management details and administrators' rights management operations are simplified, improving rights management usability and user experience.

  • FusionInsight Manager adopts the role-based access control (RBAC) mode to configure rights for users as required during multi-tenant management.
  • Administrator of tenants, the administrator has tenants' management rights, including viewing resources and services of the current tenant, adding or deleting sub-tenants of the current tenant, and managing rights of sub-tenants' resources. The administrator of a single tenant can be defined and the management over a tenant can be delegated to another user except the system administrator.
  • Roles corresponding to tenants, roles have all rights on the computing resources and storage resources of a tenant. During the creation of a tenant, the system automatically creates a corresponding role. You can add a user and bind the user to the tenant role so that it can use the resources of the tenant.

Clear Resource Management

  • Self-Service Resource Configuration

    In FusionInsight Manager, you can configure the computing resources and storage resources during the creation of a tenant and add, modify, or delete the resources of a tenant.

    Rights of the role that corresponds to the current tenant are updated automatically when you modify the computing resources and storage resources of a tenant.

  • Resource Usage Statistics

    Resource usage statistics is critical for administrators to make O&M decisions based on the status of cluster applications and services, improving the cluster O&M efficiency. The FusionInsight Manager displays the resource statistics of tenant through the Resource Quota, including the dynamic computing resource VCores and Memory of tenant and the usage statistics of HDFS storage resources (Space).

    When the tenant administrator is bound to a tenant role, the tenant administrator has the rights to manage the tenant and use all resources of the tenant.

  • Graphical Resource Monitoring

    The resource graphical monitoring supports the graphical display of monitoring items listed in Table 1, as shown in Figure 2

    Figure 2 Refined monitoring

    Real-time monitoring data is displayed by default. You can click to customize a time range. The default time ranges are as follows: 4 hour, 8 hours, 12 hours, 1 day, 1 week, and 1 month. Choose > Customize to export the monitoring item information.
