FIWARE Orion：多租户和联盟

Question

I would like to know how can I create tenants in Orion. I understand that you need to inform Orion of the multitenancy by adding the -multiservice parameter. However, I do not know what is necessary to create, indeed, a tenant.

From what I have seen in the documentation, my guess is that you just need to add the Fiware-Service header in each HTTP request. Therefore, if you send a updateContext with a Fiware-Service=t_01 Orion will automatically create that tenant. Is this right?

In addition to this, I also would like to know if multitenancy works correctly (or is planned to work correctly) in the following scenario:

In other words, is it possible to have several Gateways, each one with an Orion with one or more tenants, and all the Orions of all the Gateways federated to a global Orion in the cloud? Will the tenancy be respected in the global orion?

Thanks.

Answer 1

Your are right: Orion creates tenants "on the fly", the first time a create entity/registry operation in the given tenant is processed.

Regarding the scenario in the picture I understand that you refer to the federation approach described in this section in the manual , based on notifyContext. Given that Orion includes the Fiware-Service header in notifications, it should work.
