Abiquo 5.4 offers complete multi-cloud storage limits per tenant.
In Abiquo 5.3 versions, you could create limits for private cloud datacenters and for tenants in multiple datacenters.
Now in Abiquo 5.4, you can also create storage service level limits per tenant in public cloud.
Abiquo 5.4 automatically onboards the datastore tiers from public cloud providers and it creates abstract datastore tiers to represent each tier in all locations.
