AccessType
  • Until 4.4, CloudStack did not distinguish between a read-only access Vs read-and-use access Vs operate access. 
  • CloudStack access control layer always checked if the caller is owner of the entity and granted all types of access based on that. 
  • With IAM feature following are the types of entity access one can specify:
    1. ListEntry  (read only access)
    2. UseEntry  (read and use access)
    3. OperateEntry (operate/execute access)
