Disaggregated cloud-native network architecture
A cloud based network includes a plurality of nodes, each of which include at least one containerized microservice that enables intent-driven operation of the cloud based network. One or more resource controllers, each designated to manage a custom resource, communicate with a master controller of the node to manage operational and configuration states of the node and any microservices containerized within the node. The master enables a user to monitor and automate the management of microservices and the cloud based network as a whole. The containerized microservice architecture allows user customizable rendering of microservices, reconciliation of old and new versions of microservices, and facilitated management of a plurality of nodes.
