 - **Compatibility** - CNFs should work with any Certified Kubernetes product and any CNI-compatible network that meet their functionality requirements.
 - **Statelessness** - The CNF's state should be stored in a custom resource definition or a separate database (e.g. etcd) rather than requiring local storage. The CNF should also be resilient to node failure.
 - **Security** - CNF containers should be isolated from one another and the host.
+- **Microservice** - The CNF should be developed and delivered as a microservice.
 - **Scalability** - CNFs should support horizontal scaling (across multiple machines) and vertical scaling (between sizes of machines).
 - **Configuration and Lifecycle** - The CNF's configuration and lifecycle should be managed in a declarative manner, using ConfigMaps, Operators, or other declarative interfaces.  
 - **Observability** - CNFs should externalize their internal states in a way that supports metrics, tracing, and logging.

+## Microservice Tests 
+#### The CNF should be developed and delivered as a microservice. The CNF Conformance suite tests to determine the organizational structure and rate of change of the CNF being tested. Once these are known we can detemine whether or not the CNF is a microservice. See: [Microservice-Principles](https://networking.cloud-native-principles.org/cloud-native-microservice-principles):
+*  Check if the CNF have a reasonable startup time.
+*  Check the image size of the CNF.
+
 ## Scalability Tests  
 #### The CNF conformance suite checks to see if CNFs support horizontal scaling (across multiple machines) and vertical scaling (between sizes of machines) by using the native K8s [kubectl](https://kubernetes.io/docs/reference/kubectl/cheatsheet/#scaling-resources) command to:
 *  Test increasing/decreasing capacity
