**Questions**
* Currently, candidates are either service instances or cloud regions. As new services are on-boarded, this can be evolved to represent different types of resources.
| ``inventory_group`` | Constraint that enforces two or more demands are satisfied using candidates from a pre-established group in the inventory. |
| ``region_fit`` | Constraint that ensures available capacity in an existing cloud region for an incoming demand. |
| ``zone`` | Constraint that enforces co-location/diversity at the granularities of clouds/regions/availability-zones. |
+| ``hpa`` | Constraint that recommends cloud region with an optimal flavor based on required HPA capabilities for an incoming demand. |
+| ``vim_fit`` | Constraint that checks if the incoming demand fits the VIM instance. |
| ``license`` (Deferred) | License availability constraint. |
| ``network_between_demands`` (Deferred) | Network constraint between each pair of a list of demands. |
| ``network_to_location`` (Deferred) | Network constraint between each of a list of demands and a specific location/address. |
* These categories could be any of the following: ``disaster_zone``, ``region``, ``complex``, ``time_zone``, and ``maintenance_zone``. Really, we are talking affinity/anti-affinity at the level of DCs, but these terms may cause confusion with affinity/anti-affinity in OpenStack.
+### HPA
+
+Constrain each demand's inventory candidates based on cloud regions' Hardware platform capabilities (HPA)
+
+Requirements mapped to the inventory provider specified properties, referenced by the demands. For example, properties could be hardware capabilities provided by the platform through flavors or cloud-region eg:(CPU-Pinning, NUMA), features supported by the services, etc.
+
+**Schema**
+
+| Property | Value |
+|---------------|-------------------------------------------------------------|
+| ``evaluate`` | List of flavorLabel, flavorProperties of each VM of the VNF demand. |
+
+```yaml
+constraints:
+ hpa_constraint:
+ type: hpa
+ demands: [my_vnf_demand, my_other_vnf_demand]
+ properties:
+ evaluate:
+ - [ List of {flavorLabel : {flavor label name},
+ flavorProperties: HPACapability DICT} ]
+HPACapability DICT :
+ hpa-feature: basicCapabilities
+ hpa-version: v1
+ architecture: generic
+ hpa-feature-attributes:
+ - HPAFEATUREATTRIBUTES LIST
+
+HPAFEATUREATTRIBUTES LIST:
+ hpa-attribute-key: String
+ hpa-attribute-value: String
+ operator: One of OPERATOR
+ unit: String
+OPERATOR : ['=', '<', '>', '<=', '>=', 'ALL']
+```
+
+**Example**
+```json
+{
+ "hpa_constraint":{
+ "type":"hpa",
+ "demands":[
+ "vG"
+ ],
+ "properties":{
+ "evaluate":[
+ {
+ "flavorLabel":"flavor_label_1",

+ "mandatory": "True",
+ "hpa-feature-attributes":[
+ {
+ "hpa-attribute-key":"numVirtualCpu",
+ "hpa-attribute-value":"32",
+ "operator":"="
+ },
+ {
+ "hpa-attribute-key":"virtualMemSize",
+ "hpa-attribute-value":"64",
+ "operator":"=",
+ "unit":"GB"
+ }
+ ]
+ },
+ {
+ "hpa-feature":"ovsDpdk",
+ "hpa-version":"v1",
+ "architecture":"generic",
+ "mandatory": "False",
+ "score": "10",
+ "hpa-feature-attributes":[
+ {
+ "hpa-attribute-key":"dataProcessingAccelerationLibrary",
+ "hpa-attribute-value":"v18.02",
+ "operator":"="
+ }
+ ]
+ }
+ ]
+ },
+ {
+ "flavorLabel":"flavor_label_2",
+ "flavorProperties":[
+ {
+ "hpa-feature":"basicCapabilities",
+ "hpa-version":"v1",
+ "architecture":"generic",
+ "mandatory": "False",
+ "score": "5",
+ "hpa-feature-attributes":[
+ {
+ "hpa-attribute-key":"numVirtualCpu",
+ "hpa-attribute-value":"8",
+ "operator":">="
+ },
+ {
+ "hpa-attribute-key":"virtualMemSize",
+ "hpa-attribute-value":"16",
+ "operator":">=",
+ "unit":"GB"
+ }
+ ]
+ }
+ ]
+ }
+ ]
+ }
+ }
+}
+```
+
+### VIM Fit
+
+Constrain each demand's inventory candidates based on capacity check for available capacity at the VIM instances.
+
+Requirements are sent as an opaque request object understood by the VIM controllers or MultiCloud. Each controller is defined and implemented as a plugin in Conductor.
+
+A vim controller plugin knows how to communicate with a particular endpoint (via HTTP/REST, DMaaP, etc.), obtain necessary information, and make a decision. The endpoint and credentials can be configured through plugin settings.
+
+**Schema**
+
+| Property | Value |
+|---------------|-------------------------------------------------------------|
+| ``controller``| Name of a vim controller. (e.g., multicloud) |
+| ``request`` | Opaque dictionary of key/value pairs. Values must be strings or numbers. Encoded and sent to the vim controller via a plugin. |
+
+For example, to place two demands in different disaster zones:
+
+```yaml
+constraints:
+ check_cloud_capacity:
+ type: vim_fit
+ demands: [my_vnf_demand, my_other_vnf_demand]
+ properties:
+ controller: multicloud
+ request: REQUEST_DICT
+```
+
+**Notes**
+
+* For ONAP Beijing release the REQUEST_DICT is of the following format as defined by the policy for vim_fit. The REQUEST_DICT is an opaque request object defined through policy, so it is not restricted to this format. In ONAP Beijing release MultiCloud supports the check_vim_capacity using the following grammar.
+ ```json
+ {
+ "request":{
+ "vCPU":10,
+ "Memory":{
+ "quantity":{
+ "get_param":"REQUIRED_MEM"
+ },
+ "unit":"GB"
+ },
+ "Storage":{
+ "quantity":{
+ "get_param":"REQUIRED_DISK"
+ },
+ "unit":"GB"
+ }
+ }
+ }
+ ```
+
### Inventory Group
Constrain demands such that inventory items are grouped across two demands.
