Software Architecture

We will cover the role of quality attributes in solution architecture.

 Quality attributes in software architecture represent the question:"How should the system deliver the business requirements and guarantee its qualities?".

Since we achieve this level, we can't accept narratives about quality attributes without its consequences on architecture.

As an example of architecture quality, we can list the following as an example:

• Performance

• Interoperability 

• Usability 

• Reliability 

• Availability

• Security

• Maintainability 

• Modifiability 

• Testability

• Scalability 

• Reusability

In each of the above mentioned, #solutionarchitecture should provide:

1. Solution for each attribute, like caching component for performance

2. Component for each factor, like securiry module at all level.

3. Standards and approaches for each factor, like #OWASP for security

Finally, quality attributes and its consequences on architecture is challenging, as sometimes, we can have a contradiction between these attributrs, like usability, and security in bank account recovery as example.
