CNF Scalability

From an Orchestration perspective: Cluster Autoscaler, HPA and VPA

Handling within its own cluster

From an Automation, Control Loop (CL) perspective

OOF, SO, Multi-Cloud

CL (DCAE, Policy, CLAMP + Triggered Action)

Adding value: Handling multiple K8S, Clusters

See "SO enhancements to support CNF" presentation (3/17)

CNF Resiliency

From an Orchestration perspective: K8S Services

From an Automation, Control Loop (CL) perspective

OOF, MSO, Multi-Cloud

Secured service-to-service communication

Additional SW to be uploaded on top of K8S:

Linkerd, ISTIO, 

AAF

(VNFs only)

Do we provide any certificate or shall we rely on a Certification Manager?

Logging

Stackdriver Logging

Observability

Prometheus - https://prometheus.io/

Open-source systems monitoring and alerting toolkit

Jaeger - https://www.jaegertracing.io/

As on-the-ground microservice practitioners are quickly realizing, the majority of operational problems that arise when moving to a distributed architecture are ultimately grounded in two areas: networking and observability. It is simply an orders of magnitude larger problem to network and debug a set of intertwined distributed services versus a single monolithic application.

based on grafana technologies (UI part) 

Specific VES

Integration with Promotheus and Grafana technologies (UI) as POC by AT&T

-Check the CNF Conformance to understand what are the requirements

-Shall we integrate one of the open sources to DCAE (like we did with PNDA) or shall we create DCAE CNCF version?

Inventory

CNFs Storage

•  Secured mechanism to store/inject CNF images (Extension to Artifactory - Separate virtual repos)

CNF Security Requirements

How to address Networking back to provider network

Expansion of Container Security for K8S (out of scope from SECCOM?)

OpenTelemetry provides a single set of APIs, libraries, agents, and collector services to capture distributed traces and metrics from your application. You can analyze them using Prometheus, Jaeger, and other observability tools. - https://opentelemetry.io/

CNF Compliance:

The CNF supports OpenTelemetry-compatible tracing
– Does the CNF generate Open Telemetry compliant data?
– Is there traffic to Jaeger? 

Dual Stack Network:

•  IPv4 K8s cluster with IPv4 pods and services 
•  IPv6 

We need to understand what role does ONAP play for CNF networking. Is it exposed to CNI plugin choice? Multiple interface containers? etc.
