Solution Overview

Problem

Existing Kubernetes deployment systems face challenges in managing complex orchestration of multiple simultaneous deployments that share external resources and follow common lifecycles, leading to deployment delays and operational complexities.

Innovation Solution

The implementation of a new Kubernetes management layer that provides services for lifecycle management of a cohort of services, allowing for the monitoring and management of spawned deployments to ensure they adhere to the lifecycle of a parent deployment, thereby simplifying complex deployments and updates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple simultaneous Kubernetes deployments are orchestrated to share external resources and follow common lifecycles, then deployment coordination and resource sharing are improved, but device complexity and operational management difficulty increase

Engineering Contradiction:

Improvedeployment coordinationVSAvoidoperational management

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the complex deployment management into distinct components: parent deployments that define the overall lifecycle and spawned deployments that handle specific workloads. This segmentation allows each component to manage a subset of responsibilities, reducing the operational complexity while maintaining coordinated resource sharing and lifecycle management across the entire deployment cohort.

Inventive Principle:

Principle #1Segmentation

2Productivity

If deployment updates are rolled out at multiple sites across a region, then service coverage and availability are improved, but deployment time and operational complexity increase

Engineering Contradiction:

Improveservice coverageVSAvoiddeployment time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent implements preliminary action by pre-defining deployment cohorts with shared lifecycle parameters and resource configurations before actual deployment. This allows the system to prepare deployment templates and resource allocations in advance, enabling faster rollout across multiple sites without requiring complex real-time coordination during the actual deployment process.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If configuration changes are introduced during ongoing deployments, then adaptability and responsiveness to urgent issues are improved, but deployment stability and predictability worsen

Engineering Contradiction:

Improveconfiguration flexibilityVSAvoiddeployment stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent applies dynamics by enabling configuration changes to be introduced during ongoing deployments through the cohort management system. The parent deployment can be updated with new configuration parameters, and these changes are propagated to spawned deployments dynamically. This maintains adaptability while preserving stability through the structured cohort framework that ensures consistent lifecycle management across all deployments.

Inventive Principle:

Principle #15Dynamics

AI summary

Techniques are described for orchestrating a cohort deployment in a computing network comprising a plurality of computing nodes implementing a virtualized computing network managed by an orchestrator. The cohort deployment is managed by a deployment broker configured to coordinate the cohort deployment. The cohort deployment includes multiple deployments, where the cohort deployment comprises a parent deployment and a spawned deployment that includes a dependency on the parent deployment.
