Users, Groups and ACLs

vOneCloud offers a powerful mechanism for managing, grouping and assigning roles to users. Permissions and Access Control List mechanisms ensures the ability to allow or forbid access to any resource controlled by vOneCloud, being physical or virtual.

User & Roles

vOneCloud can manage different types of users, attending to the permissions they have over infrastructure and logical resources.

User Type Permissions
Cloud Administrators enough privileges to perform any operation on any object
Infrastructure User may access most of the functionality to manage resources
VDC Administrators manage a limited set of resources and users.
VDC Users access a simplified Sunstone view with limited actions to create new VMs
Public users access vOneCloud through a public API


VDC is the acronym for Virtual Datacenter

Group & VDC Management

A group in vOneCloud is an authorization boundary for users, but it can also be used to partition the cloud infrastructure and define what resources are available to each group.

A resource provider is a set of physical hosts and associated datastores and virtual networks, which is logically grouped into a cluster. When you assign a resource provider to a group, users in that group will be able to use resources of that cluster.

A group and an associated resource provider forms a Virtual Datacenter (VDC). VDCs are a great way to partition your cloud into smaller clouds, with their administrator and users, completely isolated from other VDCs.

Access Control Lists

vOneCloud implements a very useful ACL mechanism that enables fine-tuning of allowed operations for any user, or group of users. Each operation generates an authorization request that is checked against the registered set of ACL rules. There are predefined ACLs that implements default behaviors (like VDC isolation), but they can be altered by the cloud administrator.


Writing (or even reading) ACL rules is not trivial, more information about ACLs here.
