Feature: Private host, cluster, pod

Feature: Assign resources to domain/account

 

Background: Currently, CloudStack allows cloud admins to dedicate a zone to a tenant. While this is useful in certain scenarios, for several end-users this is a very expensive offering. This feature is to enable more economical options, but still preserve several of the benefits of the private zone offeringThis feature allows admins to dedicate resources to a specific tenant that needs private infrastructure for additional security or performance guarantees. This feature also allows admins to dedicate resources to resellers. Re-sellers in turn can ‘resell’ the infrastructure to their customers.

Requirements:

-          Root Admins must be able to dedicate a zone, pod or cluster or host to a specific domain or account

-          Alternatively, a host or cluster or pod or zone can be "implicitly" dedicated - this flag's description will be clarified below

-          A service offering can optionally have an "implicitly" dedicated flag on - this flag's description will be clarified below

-          When deploying a VM, end user can optionally specify it to be placed on a dedicated resource

-          Only VMs that belong to the domain/sub-domain/accounts should be deployed/started on the dedicated (implicit and explicit) hosts under the zone/pod/cluster/host

-           if a "non-dedicated" VM is requested and there is no space available from non-dedicated area in the cloud, the request must fail, even if there is space in the dedicated area

-          admin must be able to live migrate of such a VM to a resource not owned by the account, but an alert must be generated

-          In general, CloudStack must detect and provide warning of inappropriate location for a VM (such as a dedicated VM on a non-dedicated host) - this is not a specific requirement of this feature, but more of a generic requirement

-          Non-requirement: Must be able to dedicate a primary storage to an account

-          at this time, there is no requirement for the domain/sub-domain admins to manage the resource - the root admin will remain the owner of the resources
