Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration is used to create resilient infrastructure across multiple cloud providers, then flexibility and control are improved, but complexity and time consumption increase
Solution Approach 1:
The system enables self-service automation where the infrastructure provisioning process automatically configures and deploys resilient infrastructure across multiple cloud providers without requiring manual intervention. The automated system manages the complexity internally while providing users with simple deployment commands, resolving the contradiction between operational ease and system complexity.
Solution Approach 2:
An automated intermediary system is introduced between the user and the complex multi-cloud infrastructure provisioning process. This intermediary handles the complexity of configuring resilient infrastructure across multiple providers by translating high-level user requirements into detailed deployment configurations, thereby maintaining flexibility while reducing perceived complexity.
2Adaptability or versatility
If manual configuration is used to create resilient infrastructure, then customization capability is improved, but error rate and maintenance effort increase
Solution Approach 1:
The system uses template-based copying where pre-configured infrastructure blueprints are replicated across multiple cloud providers. These templates encode best practices and proven configurations that reduce errors while maintaining customization capability through parameterization. Users can customize deployments by modifying template parameters rather than creating configurations from scratch, thereby reducing error rates while preserving adaptability.
Solution Approach 2:
The system enables customization through parameter changes rather than structural modifications. By allowing users to configure infrastructure through parameter adjustments in standardized templates, the system maintains reliability through consistent structural patterns while achieving customization goals, thereby reducing configuration errors.
3Reliability
If extensive manual configuration is performed, then infrastructure resilience is improved, but deployment time increases
Solution Approach 1:
The system performs preliminary action by pre-configuring resilient infrastructure templates with all necessary resilience configurations before deployment. These templates are prepared in advance with best practices for multi-cloud resilience already embedded, allowing rapid deployment without sacrificing resilience. The complex resilience configurations are created beforehand and can be quickly replicated across cloud providers.
Solution Approach 2:
The automated system performs the extensive configuration work that would otherwise require manual effort, thereby reducing deployment time while maintaining infrastructure resilience. The self-service automation executes complex provisioning tasks across multiple cloud providers simultaneously, achieving both speed and resilience that would be difficult to balance manually.
4Productivity
If automated infrastructure provisioning is implemented, then deployment speed is improved, but initial setup complexity increases
Solution Approach 1:
The automated provisioning system is segmented into modular, reusable components and templates. This segmentation allows the complex automation logic to be broken down into manageable units that can be independently configured and combined. Users only need to select and parameterize appropriate templates for their needs, reducing the perceived initial setup complexity while maintaining high deployment speed through automated execution.

AI summary
A method for creating an infrastructure for a plurality of cloud providers includes receiving input data corresponding to the infrastructure for the plurality of cloud providers. The input data includes a plurality of deployments, a DNS zone including a single DNS name, and a global load balancer. The method also includes modifying a terraform configuration file based on the input data to define the infrastructure and thereby improve a distribution across the plurality of cloud providers. Modifying the terraform configuration file includes defining a respective path and respective deployment rules for each deployment of the plurality of deployments, defining the DNS zone and the single DNS name thereof, and defining one or more routing rules for the global load balancer. The method also includes creating the infrastructure based on the terraform configuration file to provide enhanced resiliency across the plurality of cloud providers.
