- Use Cases for Integration testing
- vCPE
- This does not cover In the current state, this use case cannot support the intent "Infra HA for VMs in a VNF"
- vDNS
- Makes sense for Can support intent "Infra HA for VMs in a VNF" and "Infrastructure Resource Isolation for VNF"
- Nothing additional needed in OOF or MC
- May need changes Changes needed in SO - Ramki/to call OOF API
- Matti to follow up with
- Shankar
- vCPE
- Policy DB – is there any restriction on the type of json objects storethat can be stored?
- Matti to follow up with Ankit

- Deployment-Intent
- 1. "Infrastructure Resource Isolation for VNF" – { "qosProperty": { {"Burstable QoS": "TRUE", "Burstable QoS Oversubscription Percentage": "25"} } }
- Casablanca Plan
- Only certain pre-defined over-subscription values are allowed to reflect practical deployment and simplify implementation
- Dublin & Beyond Potential Plan
- Creating instance types on demand for private clouds - to study
- Casablanca Plan
- 2. Cloud-agnostic Workload Deployment Policy (Intent) is not passed in the SO → MC API
- Casablanca Plan
- Cloud-Agnostic Workload Deployment Policy (Intent) can be stored in the form of Multi-Cloud configuration file(s) in OOM K8S Persistent Volumes to simplify implementation.
- Dublin & Beyond Potential Plan
- Pass this policy (optionally with specific realization options) from SO → MC. This is captured in the R4 and beyond workflow (Edge Scoping - Beyond Casablanca).
- Casablanca Plan
- 1. "Infrastructure Resource Isolation for VNF" – { "qosProperty": { {"Burstable QoS": "TRUE", "Burstable QoS Oversubscription Percentage": "25"} } }
- Policy-based capacity check & cloud-selection
- 3. Tenant Information is not passed in the OOF → MC API
- Casablanca Plan
- The tenant information is derived from a simple mapping function per <cloud owner, cloud region>
- A simple mapping would be a tenant per <cloud owner, cloud region> as part of Multi-VIM plugin configuration.
- Need to make sure that this scheme is synchronous with the SO → MC API path
- The tenant information is derived from a simple mapping function per <cloud owner, cloud region>
- Dublin & Beyond Potential Plan
- Pass Tenant Information per <cloud owner, cloud region> in the OOF → MC API<cloud owner, cloud region> in the OOF → MC API
- Casablanca Plan
- 4. Capacity Check for Public Clouds is not supported
- Casablanca Plan
- Public Clouds always pass the capacity check
- Dublin & Beyond Potential Plan
- Quota in Public Clouds - to study
- Casablanca Plan
5. VM Instance type/VM Feature Group dollar-cost-based cloud selection
Casablanca Plan
VM Instance type/VM Feature Group dollar-cost-based cloud selection is not mandatory for all Multi-Cloud Plugins
If a Multi-Cloud Plugin does not support cost based on "dollarCostEvaluationVM-Type" and/or "dollarCostEvaluationVM-FeatureGroup"
- The workload deployment cost is computed as a fixed cost per plugin
- Casablanca Plan
- Public Clouds always pass the capacity check
- Public Clouds always pass the capacity check
Dublin & Beyond Potential Plan
- Quota in Public Clouds - to study
- Deep dive further on dollar-cost-based cloud selection models/implementation for public/private clouds
65. The workload instance type model (Note 1 below) is not passed from OOF → MC. Rationale below.
Currently, the VNFC model supports only compute/memory/local storage. A comprehensive VNFC model needs to include HW generation (Intel Broadwell/Haswell, ARM etc.), HPA details (SR-IOV etc.) and more.
Casablanca Plan
Since the VNFC model standardization is in progress, VNFC mapping to VM Instance Type (OpenStack Flavor, Azure M4 etc.) happens in the Multi-Cloud plugin through configuration.
- Note 1: An exception to the rule is a simple capacity check based on VM compute/memory/local storage which can be supported by the current instance type model.
- Dublin & Beyond Potential Plan
- Align with the modelling modeling work and make progress
- 3. Tenant Information is not passed in the OOF → MC API
