Users of Resource Orchestrator

The users who perform configuration and operation of the infrastructure platform for operations using Resource Orchestrator are given below.

For details on the roles of users, refer to "Chapter 4 User Roles in Resource Orchestrator [Cloud Edition]".

Table 3.1 User
Department	User	Overview
Service User Department	Tenant User	A person who performs configuration, operation, or maintenance of business systems. Systems are configured on an allocated logical platform (L-Platform).
Service User Department	Tenant administrator	The manager of a service user department which performs configuration, operation, and maintenance of a logical platform (L-Platform). In Resource Orchestrator, the unit for division of management and operation of resources based on organizations or operations is called a tenant. They manage tenant users in tenants and logical platforms (L-Platforms).
Service Provision Department	Infrastructure Administrators	A manager of a service provision department which performs configuration, operation, and maintenance of an entire infrastructure. Logical platforms (L-Platform) are allocated according to requests from service user departments.
Service Provision Department	System administrator	A system administrator who manages the entire system. They install Resource Orchestrator and configure the necessary settings. OS administrator privileges are required for these operations. Usually, the roles of infrastructure administrator and system administrator are performed by the person.

Functions Available to Users of Resource Orchestrator

The functions available to users using the service portal provided by Resource Orchestrator (ROR console) are as shown below.

Table 3.2 Functions Available to Users of Resource Orchestrator
Functions		User	Overview
Logical platform (L-Platform) creation and management	Power operations and snapshots	Tenant User	Uses logical platforms (L-Platforms) via remote desktop or by using SSH. Power operations such as starting or stopping of the logical platform (L-Platform) can be performed. Collection and restoration of snapshots of the logical platform (L-Platform) can also be performed.
	Reconfiguration	Infrastructure Administrators	Infrastructure administrators can modify the server specifications such as CPUs, memory capacity, and disk capacity defined in the logical platform (L-Platform), when requested by tenant users or tenant administrators. Effective use of resources can be realized, since resources can easily be increased or reduced according to the workload fluctuations of logical platforms (L-Platforms) being used.
	Automation of network settings	Infrastructure Administrators	Configures rules and definitions for the network devices automatically, when creating, modifying, and deleting logical platforms (L-Platforms). Automating network settings enables reduction of the operational workload of tenant users.
	Logical platform (L-Platform) creation	Tenant User	Deploys logical platforms (L-Platforms) including physical and virtual servers automatically, based on templates. Automated configuration can prevent configuration errors and enable quick provision of logical platforms (L-Platforms).
	Subscription	Tenant User	Tenant users can apply to use a logical platform (L-Platform).
	Approval and Assessment	Tenant administrator Infrastructure Administrators	Applications for use can be double-checked with approval by the tenant administrator and with review by the infrastructure administrator. This promotes the appropriate use of resources by checking the validity of the application for use.
Visualization of the operational status of resources and accounting management	Accounting	Tenant administrator	Displays the usage charges for each tenant or each logical platform (L-Platform), and sends notification by e-mail. Allocates appropriate costs to resources.
	Monitoring the Operation Status of Resources	Tenant User Tenant administrator	Tenant users can monitor the operational statuses of allocated logical platforms (L-Platforms). Tenant administrators can monitor all logical platforms (L-Platforms) which belong to the tenants being managed. Infrastructure administrators can check the free space, and monitor the thresholds for all resources managed in resource pools.
Platform standardization using templates	Creating and releasing L-Platform templates	Tenant administrator Infrastructure Administrators	Creates a template called an L-Platform template for the entire infrastructure or for each tenant. This promotes effective operation by determining the user department logical platform (L-Platform) format (standardization) and using it as a template.
Resource Management in Multi-tenant Environments	Monitoring Resource Pool Use Rate	Tenant administrator Infrastructure Administrators	Tenant administrators can check the free space (utilization) of the resource pools which belong to the tenant being managed, and monitor their thresholds. Infrastructure administrators can check the free space (utilization) of the resource pools which can be used by multiple tenants, and monitor their thresholds. The usage status of ICT resources can be easily checked using the dashboard. Displays performance information and configuration information of logical platforms (L-Platforms), can forecast demands of resource pools, and simulate VM guest relocation.
	Resource pool management	Infrastructure Administrators	Manages all ICT resources (in a resource pool). Effective use of ICT resources can be realized based on changes in the amount of usage.
	Tenant management	Infrastructure Administrators	Creates, modifies, and deletes tenants to manage divided resources. Enables ICT resources to be shared between multiple departments while ensuring security.
System management	User role management	Tenant administrator Infrastructure Administrators	Tenant administrators can add, modify, and delete tenant users. Infrastructure administrators can limit operations available to each user, and the resources which can be operated.
	Server integration	Infrastructure Administrators	Operation of physical and virtual servers is possible using a single window, with no need to be aware of the differences of the server hardware models, or the OS types.
	Monitoring and visualization of system status	Infrastructure Administrators	Visualizes the statuses of blade servers, network links, and power consumption, and monitors the system status.
	Server hardware maintenance	Infrastructure Administrators	Creating backups of system disk contents before performing any OS or software installation, configuration changes, deletion or patch application can drastically reduce the time necessary to restore a server to its original state if hardware or software problems occur. When VM guests have been migrated to a different VM host for operation or maintenance of servers, it is possible to restore them to their original VM host using a single operation. When a server fails, the system can be restored by switching over primary servers with pre-assigned spare servers.
	Ensuring network security	Infrastructure Administrators	Even if there are no dedicated firewall devices, security can be ensured for each tenant, each logical platform (L-Platform), or each segment.
	Disaster recovery of systems	Infrastructure Administrators	Quickly recovers logical platforms (L-Platforms), by copying the contents of disks on the primary site to a standby site.

Operation Flow

The operation flow of a logical platform (L-Platform) is shown below.

Figure 3.3 Operation Flow

Table 3.3 Operation Flow
Phase	Work	Operator	Overview
Preparation	Resource pool registration	Infrastructure Administrators	Registers managed resources in the resource pool.
	Template registration	Infrastructure Administrators	Registers templates that can be used by all tenants, with Resource Orchestrator.
	Template registration	Tenant administrator	Registers tenant-specific templates after modifying the template common to all tenants.
Application	Logical platform (L-Platform) creation	Tenant User	Applies for logical platform (L-Platform) creation.
	Approval (Omissible)	Tenant administrator	Approves usage applications from tenant users. This work is optional.
	Review (Omissible)	Infrastructure Administrators	Assesses usage applications from tenant users. This work is optional.
Operation	Receive notification of completion	Tenant User	Once the logical platform (L-Platform) is created, notification of completion is received. Upon receipt of the notification of completion, the logical platform (L-Platform) is ready to use.
	Server operation	Tenant User	Uses logical platforms (L-Platforms) via remote desktop or by using SSH. Power operations such as starting or stopping of the logical platform (L-Platform) can be performed. Collection and restoration of snapshots of the logical platform (L-Platform) can also be performed.
	Monitoring of resource operation	Tenant User	Monitors the operational status of the logical platform (L-Platform) that they are using.
	Calculation of charges (Monitoring)	Tenant administrator	Monitors the usage charges for each tenant or each logical platform (L-Platform).
	Monitoring of resource usage	Infrastructure Administrators	Monitors the amount of usage of resources.
	Calculation of charges (Apportioning)	Infrastructure administrator	Infrastructure administrators can receive usage charge files for each tenant by email. Usage charge files can be used to charge each tenant. If the accounts manager, who is responsible for charging, is not an infrastructure administrator, usage charge files can be sent to the accounts manager.
