Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Customers face challenges in configuring cross-regional infrastructure for disaster recovery due to region-specific tooling and abstractions, leading to costly and complex solutions that are difficult to update, and there is a need for standardized and automated processes to manage infrastructure configurations across geographical locations.
Innovation Solution
A system utilizing infrastructure code and scripts within an Infrastructure as Code (IaC) framework automatically generates and deploys infrastructure configurations across different geographical locations, incorporating changes over time, and includes client-side companion libraries for security and permissions management, enabling active-active disaster recovery solutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If customers manually configure cross-regional infrastructure for disaster recovery, then they can achieve resilient workloads across geographical locations, but the solution becomes costly and complex to develop, deploy, and update
Solution Approach 1:
The system enables self-service disaster recovery by automatically detecting infrastructure changes in the primary region and propagating them to secondary regions without requiring customer intervention. The service provider's system autonomously manages the complexity of cross-regional infrastructure configuration, allowing customers to achieve resilience while the system handles the complexity internally.
Solution Approach 2:
The patent introduces an intermediary service layer between the customer and the underlying cross-regional infrastructure. This intermediary automatically manages infrastructure code generation, change detection, and propagation across regions, shielding customers from the complexity while ensuring reliable disaster recovery configurations are maintained.
2Ease of manufacture
If customers use region-specific tooling and abstractions for cross-regional infrastructure, then they can leverage existing service provider capabilities, but the solutions become difficult to update and maintain
Solution Approach 1:
The system creates a universal infrastructure code representation that can be deployed across multiple geographical regions with different region-specific tooling and abstractions. The infrastructure code serves multiple functions: it defines the desired state, detects changes, and propagates updates across regions, making the solution adaptable to different regions while maintaining ease of deployment through standardized processes.
Solution Approach 2:
The system dynamically adapts to regional differences by automatically generating and updating infrastructure code based on detected changes in the primary region. Rather than using static, region-specific configurations, the system continuously synchronizes infrastructure definitions across regions, ensuring update flexibility while leveraging existing service provider capabilities in each region.
3Reliability
If advanced customers deploy custom cross-region applications, then they can achieve disaster recovery capability, but the solutions are costly and complex to develop and deploy
Solution Approach 1:
The system provides self-service disaster recovery by automatically detecting infrastructure changes and propagating them to secondary regions without requiring advanced customer expertise or custom application development. The service provider's system autonomously manages the disaster recovery configuration, reducing development costs while maintaining reliable cross-region capability.
Solution Approach 2:
The system uses infrastructure code to define and copy the desired infrastructure state across multiple geographical regions. Rather than requiring customers to manually deploy and configure custom applications in each region, the system automatically copies and synchronizes infrastructure definitions, significantly reducing development and deployment costs while ensuring consistency across regions.
4Adaptability or versatility
If infrastructure configurations are manually managed across geographical locations, then customization is possible, but automated management and standardization cannot be achieved
Solution Approach 1:
The system achieves automated infrastructure management while preserving customization capabilities through self-service. The system automatically detects changes in infrastructure code, determines the desired state, and propagates updates across regions without manual intervention. Customers can customize their infrastructure through infrastructure code definitions, and the system automatically manages the synchronization, combining adaptability with automation.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring infrastructure code changes in the primary region and automatically propagating those changes to secondary regions. This feedback loop ensures that infrastructure configurations remain synchronized across geographical locations, enabling automated management while maintaining the ability to customize infrastructure through code-based definitions that can be updated as needed.

AI summary
A system and method for an infrastructure as code (IaC) environment includes automatically generating different infrastructure code for different timepoints based at least in part on changes in infrastructure configurations at the different timepoints of a first virtual private cloud (VPC) so as to execute one of the different infrastructure code for a second VPC to cause deployment of one of the infrastructure configurations; and includes automatically generating or updating a script based at least in part on changes in the infrastructure code, the script to be used to deploy at least a version of the infrastructure configurations with the changes in a second VPC of a different geographical location than associated with the first VPC.
