Solution Overview

Problem

Existing methods for migrating containerized workloads across Kubernetes clusters with different processor architectures are manual, time-consuming, and error-prone, making it difficult to transition workloads between different computing infrastructure platforms.

Innovation Solution

A migration orchestrator automates the process by creating a new container image specific to the destination processor architecture, backing up metadata from the source cluster, and restoring it to the destination cluster, minimizing human intervention and enabling seamless migration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual migration process is used for containerized workloads across different processor architectures, then flexibility to choose destination cluster is maintained, but migration time and complexity increase significantly

Engineering Contradiction:

Improveflexibility to choose destination clusterVSAvoidmigration time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent introduces a migration orchestrator as an intermediary component that automates the migration process between source and destination Kubernetes clusters. The orchestrator handles architecture-specific configurations, container image translations, and metadata mappings, enabling automated cross-architecture migration while maintaining flexibility in destination cluster selection.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary actions by pre-configuring architecture-specific settings and container image translations before actual workload migration. The migration orchestrator prepares the destination cluster environment, converts container images to match the destination architecture, and validates configurations in advance, reducing actual migration time.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If manual migration process is used, then control over migration details is maintained, but error probability and operational burden increase

Engineering Contradiction:

Improveoperational burdenVSAvoiderror probability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The migration orchestrator enables self-service migration by automatically handling configuration translations, container image conversions, and metadata mappings. The system autonomously detects source cluster settings, translates them to destination cluster requirements, and executes migration without requiring manual intervention for each configuration detail, reducing operational burden and human error.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements feedback mechanisms where the migration orchestrator continuously monitors the migration process, validates configuration translations, and adjusts parameters based on destination cluster responses. This automated feedback loop ensures migration accuracy and reduces errors by verifying each step before proceeding.

Inventive Principle:

Principle #23Feedback

3Productivity

If container images are created for each processor architecture manually, then architecture-specific optimization is achieved, but migration complexity and time increase

Engineering Contradiction:

Improvemigration efficiencyVSAvoidmigration process complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The migration orchestrator provides a universal solution that handles multiple processor architectures (x86, ARM, RISC-V) through a single automated platform. It maintains a library of architecture-specific configurations and automatically selects and applies the appropriate settings based on the destination cluster's processor type, enabling multi-architecture support without requiring separate manual processes for each architecture.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system automatically changes parameters such as container image formats, CPU architecture flags, and runtime configurations based on the destination cluster's processor architecture. The migration orchestrator dynamically adjusts these parameters during the migration process, eliminating the need for manual parameter setting while ensuring architecture-specific optimization.

Inventive Principle:

Principle #35Parameter changes

AI summary

Techniques for migrating a workload between two container clusters (i.e., source and destination container clusters) that use different processor architectures are provided. In one set of embodiments, these techniques involve implementing a migration container cluster that (1) creates a backup of the workload from the source container cluster, where the backup includes metadata regarding one or more objects or resources of the workload, and (2) restores the backup on the destination container cluster, where the restoring causes a worker node of the destination container cluster to automatically retrieve, from an image repository, a container image for the workload that is specific to the second processor architecture and deploy the container image as a running container on the worker node.
