Question

Explain why design conflicts might arise when designing an architecture for which both availability and security requirements are the most important nonfunctional requirements.

Answer 1

Generally the most non-functional requirements in this architecture are as follows.

1. Performance
2. Safety
3. Security
4. Availability
5. Maintainablity

The design conflicts might arise when designing an architecture for which both availability and security requirements are the most important non-functional requirements.

The reasons as follows

• The system architecture throws the robustness, maintainability, and performance of a system. The critical style and structure favored for an application may consequently depend on these requirements.
• In the Security requirement, the architecture must be used layered structure in a security requirement. It is an exceptional level of security validation implemented to these layers.
• In the availability requirement, the architecture must be deemed to eliminate components and so that it is feasible to change and edit elements without blocking the system.
• Security and availability are critical demands. But the major architectural conflict happened between replication and several copies in availability requirement and security requirement conflict occurred between specialization and minimal copies. So, design conflicts might arise whether a layered structure or redundant components are used when designing architecture.
