Cloud Agnostic Policy Design Considerations:
- Organize Policy per group of Cloud Region Regions or group of Cloud Regions Region
- Different cloud regions have different cloud control plane instances and naturally parallelizeable from MC and OOF and MC perspective
- One or more of the cloud regions may not respond in the to the request in time and will be excluded
Cloud Policy Example:
{
"service"
:
"cloudPolicy"
,
"policyName"
:
"oofMulti-cloudCasablanca.cloudPolicy_vCPE_VNF"
,
"description"
:
"Cloud Policy for vCPE VNF"
,
"templateVersion"
:
"0.0.1"
,
"version"
:
"oofMulti-cloudCasablanca"
,
"priority"
:
"3"
,
"riskType"
:
"test"
,
"riskLevel"
:
"2"
,
"guard"
:
"False"
,
"content"
: {
"cloudRegion" : {
"id": "All",
"intent": {
"name": "Infrastructure HA for VNF", //realization thru OpenStack-based: anti-affinity, Azure: Fault Domain or Availability set
}
"intent": {
"name": "Infrastructure Resource Isolation for VNF", // realization possible without dedicating CPU and Memory, refer to section on "Cloud Resource Partitioning for Differentiated QoS" on how this can help in offering tiered services
{"Burstable QoS": "TRUE", "Burstable QoS Oversubscription Percentage": "10"}, {"operator", "OR"}, {"Guaranteed QoS": "TRUE"}
}
}
