Techniques are disclosed for automatically inferring software-defined network policies from the observed workload in a computing environment. The disclosed techniques include monitoring network traffic flow originating from network interfaces corresponding to containers that execute components of an application, recording details of a new network connection or a change in the existing network connection, obtaining information concerning the components of the application, identifying metadata for a component involved in the new network connection or the change in an existing network connection based on a comparison of the details of the new network connection or a change in the existing network connection and the information concerning the components of the application, generating a network policy for the component using at least the metadata for the component, and integrating the network policy for the component into a deployment package for the application.

Automatically inferring software-defined network policies from the observed workload in a computing environment

Techniques are disclosed for generating network security policies for different versions of a component of an application deployed in a computing environment where the different versions have potentially different network requirements and the different versions operate together at the same time in the computing environment. The disclosed techniques include capabilities for enabling different versions of a component of a containerized application to co-exist at the same time on different computing nodes in a cluster of nodes in a containerized environment that deploys and executes the application. The techniques additionally include capabilities for enabling different network policies to be generated for the different versions of the component, where each component has potentially different network requirements. The techniques provide a mechanism to create precise, per-component network policies, while respecting the overall coarse-grained policies of the containerized application.
