Group¶

Purpose of This Document¶

This document describes the definition of Region, Zone and Group, which are the resource accommodation units.

Note

-Wasabi object storage is provided in a different Wasabi region than the traditional Enterprise Cloud region.
-TIBCO Spotfire®︎ is offered in a different region than the traditional Enterprise Cloud region.
-Arcserve UDP Cloud Direct is offered in a different region than the traditional Enterprise Cloud region.

Overview¶

Customers can configure up to three tiers of location information for each menu as follows:

Image of Region, Zone and Group

Region¶

Details¶

Region is the superordinate concept of Zone, and can have multiple Zones underneath one Region.

This means “1 Region = n Zones”. Zone does not cross over Regions.

Region is a unit of administrative system in this service and mentions collectible unit of countries or regions mainly(*1).

Note

*1: Please note the unit does not guarantee to separate to country or region.

Please refer to “Zone/Group in Each Region” which stated below for details information like location in each region.

Image of Region

What Customers Can Do¶

As mentioned previously, Region is a collectible unit of countries or regions.

Therefore, it becomes possible for Customers to cope with large-scale disaster at the levels of countries or region.

Furthermore, if the region differs, management system unit is also differ.

By dividing Regions, Customers can design independent systems on their own at the Region level.

Zone¶

Details¶

Zone is the subordinate concept of Region, and the superordinate concept of Group. There are multiple Zones within one Region, and one Zone can have multiple Groups underneath itself.
In other words, following equations logically make sense in essence, “1 Region = n Zones”, “1 Zone = n Groups”.
Zones never cross over their Regions. Moreover, Groups do not cross over their Zones.
Zone primarily is a unit of a group of building housing infrastructure.

Image of Zones

What Customers Can Do¶

As mentioned, Zone means the group of buildings housing infrastructure. By dividing zone, Customers can distribute the buildings by themselves. This enables Customers to realize the countermeasure for the building-level of disasters.

Group¶

Details¶

Group is the subordinate concept of Zone. There are multiple Groups within one Zone. It means “1 Zone = N Groups”. Group means the set of infrastructures. Services which can select Group can select group of infrastructures. Group usually means set of goup of servers, switches or storages.

Image of Groups

What Customers Can Do¶

As mentioned, Group is the set of infrastructures, so Customers can distribute their accommodated servers and switches by dividing a Group, By doing so, they can activate to cope with the physical failures and errors of servers or switches.

Difference of Groups in among Baremetal Server Menu, Virtual Server Menu and Storage Menu¶

This Note complements the difference of concept of Groups in among Baremetal Server Menu, Virtual Server Menu and Storage Menu.

Group in Baremetal Server Menu¶

Group in Baremetal Server is the unit of infrastructure which consists of multiple switches.
Customers can select one Group out of multiple Groups.
By dividing Groups, Customers’ Baremetal Servers are always connected to physically different swithes.
(If Customers configure Baremetal Server into the same Group, then Baremetal Server can be connected to the same switch.)
As such, this enables Customers to provision their system with physically-redundant switches.

Group in Baremetal Server Menu

Group in Virtual Server Menu¶

Group in Virtual Server is the unit of infrastructure which consists of multiple physical servers.
Customers can select one Group out of multiple Groups.
By dividing Groups, Customers’ Virtual Servers are always deployed within the different physical servers.
(If Customers create Virtual Server in the concurrent Group, then Virtual Server could be created in the con current Physical Server.)
As such, this enables Customers to provision their system with physically-redundant servers.

Group in Virtual Server Menu

Group in Storage Menu¶

Group in Storge is the unit of infrastructure which consists of multiple storages.
Customers can select one Group out of multiple Groups.
By dividing Groups, Customers’ Storage are always deployed within the different physical storages.
(If Customers create Storage in the concurrent Group, then Storgae could be created in the con current Physical Storage.)
As such, this enables Customers to provision their system with physically-redundant storages.

Group in Storage Menu

Note

Wasabi object storage is not included in the group concept above.

Redundant configuration using multiple groups¶

In this service, two groups (Group A, Group B) are provided for one zone, and we recommend that you configure a group A and a group B when forming a redundant configuration within a zone.

NOTE: Because redundant configuration within a single group may be accommodated in the same facility (switch, physical host, storage).
With this service, there is a possibility to provide Group C, D, E, F, G ... for reasons such as difficulties in reinforcing within Group A or Group B.

In this case, we recommend grouping redundancy with “Group A, C, E ...” and “Group B, D, F ...”.

NOTE: Redundant configuration in group A, C, E ... and “Group B, D, F ...”, Distributing accommodation facilities (switches, physical hosts, storage) if the group differs Although it is possible to do, there is a possibility that construction time concerning accommodation facilities will be the same.

In this service, for periodic maintenance, construction will be carried out in the time zone defined by Maintenance Window We do,

For the construction time to be carried out in the maintenance window (the time during which you actually work and may be affected)

We plan to avoid duplication between “Group A, C, E ...” and “Group B, D, F ...”.

For this reason, when a redundant configuration is formed with “Group A, C, E ...” and “Group B, D, F ...”, scheduled maintenance work time for accommodating facilities (switches, physical hosts, storages) can

Recommended configuration for configuring redundant configuration with multiple groups

Note : Tenant¶

Details¶

When creating resource, Tenant is the highest concept Customers need to set, and is like a workspace.
It is not accommodation unit but the unit of User Permission Groups; i.e., this is conceptually different from the infrastructure accommodation unit of Region / Zone / Group.
Fundamentally, in order for Customers to utilize respective services, they are required to create Tenants. And underneath the Tenants comes Resource in creation (although there may be exceptional cases).
in case of creating Tenant, customers need to specify Region Tenant belongs to.
Cusotmer can create more than one tenant in one Region but  Customer can not create a tenant across regions.
Bacause the scope of Tenant is as same as Region, Customer can create resources in one Tenant(=Region) evenif the resources is not located same Zones/Groups.

*1：Customers cannot assign a Region directly, but by assigning Tenants, they can specify the Region they would like to in essence.

*2: This service does not have the concept of Region, however, Customer need to select tenant because each service is required to belong to any Region.

Note

As for the menu that Customers can assign up to Group, suchu as Baremetal Server, Virtual Server and Block Storage (Provisioned I/O Performance), they can assign both Zone and Group by selecting hyphen-connected parameters in pairs such as “zoneX - groupX” when they select from the list of “Zone/Group”. For example, Zone and Group selected at “zone1-groupa” means the Customers will be accommodated at Group A in Zone 1 and “zone1-groupb” means the Customers will be accommodated at Group B in Zone 1.

Zone/Group in Each Region¶

Following is the information of Zone and Group in each Region:

Country	Area	Region Name	Zone Name	Datacenter	Group Name

Note

For this service, the storage unit for creating various resources is region/zone/group.As mentioned previously, regions are units of the management system.By separating regions, you can distribute the impact of your management system, but because regions are only a unit of management system, different regions can have the same country or region.On the other hand, in order to supplement the geographical concept, the units of countries and regions to which each region belongs are classified as “Area” and are shown in the table above.By separating areas, customers can take disaster countermeasures and distribute them at the national and regional levels.

Note

JP1 Region has stopped creating new tenants on April 26, 2018.
JP2 Region has stopped creating new tenants on March 31, 2021.
JP5 Region has stopped creating new tenants on May 19, 2021.
JP4 Region has stopped creating new tenants on September 30, 2021.
On March 31, 2023, all regions except the JP region will be discontinued.
