Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple code bases are used for each tenant, then customization flexibility is improved, but system complexity and operational costs increase
Solution Approach 1:
The system segments tenant-specific customizations into separate configuration files and deployment manifests, while keeping the core code base unified. This allows each tenant to have customized behavior through configuration rather than code duplication, reducing overall system complexity while maintaining flexibility.
Solution Approach 2:
A single code base is designed to serve multiple tenants with different requirements through a universal architecture that supports tenant-specific configurations. The system can dynamically adapt to different tenants' needs without requiring separate code bases, achieving both simplicity and flexibility.
2Adaptability or versatility
If separate maintenance is performed for each tenant, then tenant-specific requirements are met, but deployment time for updates and features increases
Solution Approach 1:
Tenant-specific configurations are prepared in advance as separate deployment manifests and configuration files. When updates are needed, the core code base can be updated once and then deployed to all tenants simultaneously, with tenant-specific configurations already in place, significantly reducing deployment time compared to updating each tenant separately.
Solution Approach 2:
The system merges tenant-specific configurations with the unified code base through a common deployment pipeline. Updates to the core system can be propagated across all tenants in a coordinated manner, while tenant-specific customizations are preserved and applied automatically, enabling efficient bulk updates.
3Adaptability or versatility
If traditional multi-tenant architecture is used, then basic multi-tenancy is supported, but performance consistency across varying network topologies deteriorates
Solution Approach 1:
The system dynamically adapts to varying network topologies by implementing flexible deployment configurations that can be adjusted based on network conditions. Container orchestration enables dynamic resource allocation and load balancing that responds to network topology changes, maintaining performance consistency across different network environments.
Solution Approach 2:
Deployment parameters such as resource allocation, replication factors, and network configuration are made changeable based on network topology. The system can adjust these parameters dynamically or through configuration to optimize performance for specific network conditions, ensuring consistent performance across diverse topologies.
