Exam AWS Certified Cloud Practitioner topic 1 question 4 discussion

Performance efficiency: The performance efficiency pillar focuses on the efficient use of computing resources to meet requirements, and how to maintain efficiency as demand changes and technologies evolve. Operational Excellence: The operational excellence pillar includes how your organization supports your business objectives, your ability to run workloads effectively, gain insight into their operations, and to continuously improve supporting processes and procedures to deliver business value. I understand why you could think it is C, but I believe the correct answer is B (key part: as demand changes and technologies evolve)

Reference: https://aws.amazon.com/blogs/apn/the-6-pillars-of-the-aws-well-architected-framework/ My answer would be B because of the following reason: In the official documentation, for the design principle of pillar "Operational Efficiency" we don't see the work serverless computing mentioned as below: Design Principles There are five design principles for operational excellence in the cloud: Perform operations as code Make frequent, small, reversible changes Refine operations procedures frequently Anticipate failure Learn from all operational failures but we could see the "serverless computing" mentioned in pillar "Performance Efficiency" Design Principles There are five design principles for performance efficiency in the cloud: Democratize advanced technologies Go global in minutes #####Use serverless architectures##### Experiment more often Consider mechanical sympathy

Performance efficiency: This pillar considers the best way to utilize resources to achieve the best performance Operational excellence: This pillar focuses on how well an organization is able to meet it's requirements by utilizing the cloud technology. I can see why most people would think it's C, but since we're talking about the organization and not the resources being utilized by the organization, I think the more correct option should be C

C operational excellence

Performance efficiency maintains the efficiency as demand fluctuates & technology evolves. Some of its principles include: Go global in minutes Use serverless architecture Democratize advanced tech Experiment more often Have mechanical empathy

Performance excellence

B. Performance efficiency

Performance efficiency

It should be B yeah

C. Operational Excellence

option B

The reason the company has given for wanting to migrate from physical on-premises compute servers to AWS serverless compute services is that they can "take advantage of advanced technologies quickly after the migration". While performance is naturally a desired objective, this isn't the primary focus of the company in this scenario. So the answer is C. Operational Excellence

The plan to replace physical on-premises compute servers with AWS serverless compute services, aiming to leverage advanced technologies quickly after migration, aligns strongly with the "Operational Excellence" pillar of the AWS Well-Architected Framework. This pillar emphasizes the ability to run and monitor systems to deliver business value and continually improve supporting processes and procedures. Serverless computing can enable agility, automation, and rapid adoption of advanced technologies without the overhead of managing physical infrastructure, aligning well with operational excellence goals.

option B

B performance efficiency

B. Performance efficiency

as per checking should be B
