COMPUTING NODE CLUSTERS SUPPORTING NETWORK SEGMENTATION

Abstract:

Examples described herein may include transition of a distributed computing system to using a segmented network configuration. An example method includes receiving a network segmentation request at a distributed computing system. In response to the network segmentation request and during normal operation of the distributed computing system, the method includes allocating IP addresses to computing nodes of the distributed computing system based on a number of segmented networks, and applying firewall rules to open service ports of the computing nodes. Further in response to the network segmentation request and during normal operation, the method includes updating network configuration information of the computing nodes. For a computing node of the computing nodes, the method further includes publishing the allocated IP addresses, and restarting services of the computing node. The method further includes applying the firewall rules to open a subset of the service ports of the computing nodes.
