AI Technical Summary

Technical Problem

Single node deployments in orchestration platforms face challenges with disruptive updates, as they cannot perform rolling restarts and result in cluster headlessness and disruptions during planned outages, leading to increased costs and availability issues.

Method used

A method is implemented where a processor set generates a copy of the control plane node, allocates workloads to this copy, applies the disruptive update, and then reallocates workloads back to the original node upon completion, ensuring continuous operation by utilizing logical partitions and network interfaces to manage resources efficiently.

Benefits of technology

This approach allows continuous workload operation during disruptive updates, minimizes overhead, and effectively manages computing resources by forming a two-node cluster post-update, thus optimizing resource allocation and reducing downtime.

Abstract

A computer-implemented method for updating a node in an orchestration platform. A processor set receives a patch of a disruptive update for the node in the orchestration platform. The node is a control plane node that is configured to run workloads. The processor set generates a copy for the node in the orchestration platform. The processor set allocates the workloads for the node to the copy for the node. The processor set updates the node using the patch of the disruptive update. The workloads are running on the copy for the node when the node is updating. The processor set allocates the workloads from the copy for the node back to the node upon finishing the disruptive update.
