Topology Remediation for Cloud Service Lifecycle Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cloud computing systems face challenges in designing, provisioning, deploying, and managing cloud services due to the complexity of manual deployment processes and the limitations of blueprint-based approaches, which do not effectively describe physical topologies or associate policies, leading to inefficiencies and potential mistakes.
Innovation Solution
The implementation of architecture-descriptive topologies that define physical architectures of cloud services, along with a cloud service broker that supports both topologies and blueprints using a lifecycle management engine, enables policy-based management of provisioning, deployment, monitoring, and remediation processes, and integrates application models with infrastructure templates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual deployment processes are used for cloud services, then flexibility and control are maintained, but administrative time and potential for mistakes increase
Solution Approach 1:
The system enables self-service through automated topology remediation where the cloud service broker automatically detects topology violations, determines appropriate remediation actions, and executes corrections without requiring manual administrative intervention. This maintains operational flexibility while eliminating time-consuming manual deployment tasks.
Solution Approach 2:
The system performs preliminary actions by pre-defining topology templates and policies that encode desired cloud service architectures. These pre-configured templates enable automatic validation and remediation before manual intervention is needed, reducing administrative time while preserving control through policy-based guidance.
2Ease of manufacture
If blueprint-based approaches are used to describe cloud services, then service provisioning is simplified, but physical topology description and policy association capabilities are insufficient
Solution Approach 1:
The system merges blueprint-based service provisioning with architecture-descriptive topology modeling by integrating policy templates that associate both service-level and infrastructure-level requirements. This combination maintains the simplicity of blueprint provisioning while adding comprehensive physical topology description and policy association capabilities through a unified model.
3Manufacturing precision
If architecture-descriptive topologies are implemented to define physical architectures, then topology accuracy and policy association improve, but system complexity increases
Solution Approach 1:
The system segments topology description into hierarchical levels: service-level blueprints, infrastructure-level templates, and policy-level associations. This segmentation enables precise topology definition at each level while managing system complexity through modular, layered architecture that processes each segment independently.
4Productivity
If automated deployment processes are implemented, then administrative time is reduced, but complexity of management and coordination increases
Solution Approach 1:
The system implements feedback mechanisms where the cloud service broker continuously monitors deployed topology against defined templates and policies. Automatic remediation is triggered when violations are detected, creating a closed-loop control system that maintains accuracy while managing complexity through automated detection and correction rather than complex manual coordination.

AI summary
A topology remediation method includes with a remediation engine, deriving a number of remediation actions based on a number of incidents within an instantiated topology, and with a lifecycle management engine, modifying the instantiated topology based on a number of lifecycle management actions (LCMAs) determined to remediate the incidents.
