Which of the following is NOT one of the four pillars of great architecture in Azure?

  1. Performance and scalability

  2. Cost-effectiveness

  3. Security

  4. Availability and recoverability

The correct answer is: Cost-effectiveness

Cost-effectiveness is indeed an important consideration in Azure architecture, but it is not listed among the foundational pillars of great architecture in Azure. The four primary pillars typically emphasize performance and scalability, security, and availability and recoverability. Performance and scalability ensure that applications can handle varying loads and operate efficiently under different conditions. Security focuses on protecting data and resources from unauthorized access and vulnerabilities. Availability and recoverability relate to ensuring that applications remain operational and can recover quickly from outages or failures. While cost is a crucial aspect because organizations need to manage expenses efficiently, it does not qualify as one of the core architectural principles in the same way that the other three do. Thus, the answer aligns with the recognized focus on performance, security, and reliability over financial considerations.
