 Use Cases for Copper
-  * Developer Sandbox
+^ Policy ^ Description ^ Notes/Examples ^
-    * As a developer, I need a basic development environment setup with certain compute, storage, and network functions, and want this to be scripted and thus easily repeatable.
+| Network Access Control | As a tenant, I need to be sure that the only private networks connected to my VMs are owned by me or someone from my group. | OpenStack Congress: <code>error :-
+nova:vm(vm),
+neutron:network(network),
+nova:network(vm, network),
+neutron:private(network),
+nova:owner(vm, vm-own),
+neutron:owner(network, net-own),
+-same-group(vm-own, net-own)
+same-group(user1, user2) :-
+ldap:group(user1, g),
+ldap:group(user2, g) </code> |
+| Storage Access Control | As a tenant, I need to be sure that the only VMs that can attach to my private storage resources are owned by me or someone from my group. | OpenStack Congress: <code>error :-
+nova:vm(vm),
+cinder:volumes(volume),
+nova:volume(vm, volume),
+nova:owner(vm, vm-own),
+neutron:owner(volume, vol-own),
+-same-group(vm-own, vol-own)
+same-group(user1, user2) :-
+ldap:group(user1, g),
+ldap:group(user2, g) </code> |
+| Resource Reclamation | As a service provider, I need to be informed of VMs that are under-utilized so that I can reclaim the VI resources. (example from [[http://ruleyourcloud.com/2015/03/12/scaling-up-congress.html|RuleYourCloud blog]]) | OpenStack Congress: <code> reclaim_server(vm) :-
+    ceilometer:stats("cpu_util",vm, avg_cpu),
+    lessthan(avg_cpu, 1)
-  * Workload Placement
+error(user_id, email, vm_name) :-
-     * Affinity - Same Host Filter:  Local Service Instance Deployment: As a service provider, I need my software application deployed in a local environment with resources configured to meet specific quality of service criteria, so I can ensure an acceptable user experience.  Ensures that the VM instance is launched on the same compute node as a given set of instances, as defined in a scheduler hint list. This filter is analogous to the affinity rules in vSphere DRS.
+    reclaim_server(vm),
-     * Anti-Affinity - Different Host Filter: Ensures that the VM instance is launched on a different compute node from a given set of instances, as defined in a scheduler hint list. This filter is analogous to the anti-affinity rules in vSphere DRS.
+    nova:servers(vm, vm_name, user_id),
-    * Geo-Diverse Service Instance Deployment: As a service provider, I need my software application deployed in a geo-diverse environment with resources configured to meet specific quality of service, so I can ensure an acceptable user experience.
+    keystone:users(user_id, email) </code>|
+| Affinity | Ensures that the VM instance is launched "with affinity to" specific resources, e.g. within a compute or storage cluster. | This is analogous to the affinity rules in [[https://pubs.vmware.com/vsphere-50/topic/com.vmware.vsphere.resmgmt.doc_50/GUID-FF28F29C-8B67-4EFF-A2EF-63B3537E6934.html|VMWare vSphere DRS]]. Examples include: "Same Host Filter", i.e. place on the same compute node as a given set of instances, e.g. as defined in a scheduler hint list. |
-  * Load Balancing
+| Anti-Affinity | Ensures that the VM instance is launched "with anti-affinity to" specific resources, e.g. outside a compute or storage cluster. | This filter is analogous to the anti-affinity rules in vSphere DRS. Examples include: " Different Host Filter", i.e. ensures that the VM instance is launched on a different compute node from a given set of instances, as defined in a scheduler hint list. |
-    * Geo-Diverse Load-Balanced Service Instance Deployment: As a service provider, I need my software application deployed in a geo-diverse environment with resources configured to meet specific local balancing criteria, so I can ensure an acceptable user experience.
+| Geo-Diversity | As a service provider, I need my software application deployed in a geo-diverse environment with resources configured to meet specific quality of service, so I can ensure an acceptable user experience. | |
+| Load Balancing | As a service provider, I need my software application deployed in a geo-diverse environment with resources configured to meet specific local balancing criteria, so I can ensure an acceptable user experience. | |
-  * Service Failover
+| Service Failover | As a service provider, I need my software application deployed in a geo-diverse environment with resources configured to meet specific service failover, so I can ensure an acceptable user experience. | |
-    * Geo-Diverse Service Instance Deployment with Failover: As a service provider, I need my software application deployed in a geo-diverse environment with resources configured to meet specific service failover, so I can ensure an acceptable user experience.
+| Link Mirroring | As a troubleshooter, I need to mirror traffic from physical or virtual network ports so that I can investigate trouble reports. | |
+| Link Mirroring – Authorization | As a NFVaaS tenant, I need to be able to mirror traffic on my virtual network ports so that I can investigate trouble reports. | |
+| Link Mirroring – Authorization Failure | As a NFVaaS tenant, I need to be able to prevent other tenants from mirroring traffic on my virtual network ports so that I can protect the privacy of my service users. | |
+| Link Mirroring – Delegated Authorization | As a NFVaaS tenant, I need to be able to allow my NFVaaS SP customer support to mirror traffic on my virtual network ports so that they can assist in investigating trouble reports. | |
