Networking

MSR 4 is deployed as a workload within a Kubernetes (K8s) cluster and offers multiple deployment options. The diagram below illustrates the network communication between the MSR 4 components.

Network communication between the MSR 4 components varies depending on the deployment configuration.

In a closed deployment, where all components—including Data Layer services—are deployed within the same Kubernetes cluster (either as an all-in-one or high-availability setup), communication occurs over the internal workload network. These components interact through Kubernetes Service resources, with the only externally exposed endpoints belonging to MSR 4. To ensure security, these endpoints must be protected with proper firewall configurations and TLS encryption.

For deployments where Data Layer components are remote, as depicted in the diagram, communication must be secured between the Cluster IP network used by Kubernetes worker nodes and the external endpoints of the key-value (K-V) and database (DB) storage systems.

A comprehensive list of ports requiring security configurations can be found in the Network section.
