Interview Questions

What are the five pillars of the AWS Well-Architected Framework?

The five pillars of AWS Well-Architected Framework are Operational Excellence, Security, Reliability, Performance Efficiency, and Cost Optimization.

What does the Operational Excellence pillar emphasize in the AWS Well-Architected Framework?

The Operational Excellence pillar focuses on running and monitoring systems to deliver business value and continually improving processes and procedures.

What does the Security pillar of the AWS Well-Architected Framework involve?

The Security pillar involves ensuring that data is protected in transit and at rest, and encompasses areas such as identity and access management, data encryption, security audits, and incident response.

What is the focus of the Reliability pillar in the AWS Well-Architected Framework?

The Reliability pillar emphasizes the ability of a system to recover from infrastructure or service failures, automatically scale, and meet demand.

What is the Performance Efficiency pillar in the AWS Well-Architected Framework about?

Performance Efficiency focuses on using IT and computing resources efficiently. This involves selecting the right types of resources and sizes based on workload, monitoring performance, and making decisions to maintain efficiency as business needs evolve.

What is the objective of the Cost Optimization pillar in the AWS Well-Architected Framework?

Cost Optimization aims to avoid unnecessary costs. It includes understanding and controlling where money is being spent, selecting the most appropriate and right number of resource types, analyzing spend over time, and scaling to meet business needs not overprovisioning.

How does the Operational Excellence pillar differ from the Reliability pillar in the AWS Well-Architected Framework?

While both pillars concern performance, the Operational Excellence pillar is more focused on the process and procedures to deliver business value while the Reliability pillar is about the system’s ability to recover from failures and dynamically meet demand.

What is the main difference between the Security and Performance Efficiency pillars in the AWS Well-Architected Framework?

The Security pillar focuses on protecting information and systems, whereas the Performance Efficiency pillar focuses on using resources efficiently to meet system requirements, and maintaining that efficiency as demand changes and technologies evolve.

How does the Cost Optimization pillar in the AWS Well-Architected Framework differ from the Operational Excellence pillar?

While Cost Optimization focuses on how to avoid unnecessary costs and manage the cost of operations, the Operational Excellence pillar revolves around how to run systems and improve processes to deliver business value.

What distinguishes the Reliability pillar from the Performance Efficiency pillar of the AWS Well-Architected Framework?

While both pillars concern system performance, Reliability primarily deals with system recovery from failures and maintaining performance despite changes in demand, whereas Performance Efficiency focuses on effectively using computing resources, monitoring performance, and adapting as the business needs change.

How does the Security pillar differ from the Cost Optimization pillar in the AWS Well-Architected Framework?

The Security pillar prioritizes the protection of data and systems, touching on elements like encryption, identity and access management, and incident response. In contrast, Cost Optimization focuses on avoiding and controlling costs, choosing appropriate resources, and scaling effectively.

What differentiates the Operational Excellence pillar of the AWS Well-Architected Framework from the Performance Efficiency pillar?

The Operational Excellence pillar focuses on processes and procedures that deliver business value and the ability to improve them continuously. The Performance Efficiency pillar, on the other hand, emphasizes the effective utilization of IT resources to meet system requirements while responding to changes in demand or technology.

How distinct is the Cost Optimization pillar from the Reliability pillar in the AWS Well-Architected Framework?

While Cost Optimization involves managing and reducing unnecessary costs within the system, the Reliability pillar focuses more on the ability of the system to recover from possible failures and to meet demand changes.

What makes the Security pillar distinct from the Operational Excellence pillar in the AWS Well-Architected Framework?

The Security pillar involves everything required to protect data and systems, from encryption to incident response. On the other hand, the Operational Excellence pillar focuses on the running of systems to deliver value and the continuous improvement of processes and procedures.

What separates Performance Efficiency in the AWS Well-Architected Framework from Cost Optimization?

Cost Optimization focuses on ensuring that the cloud architecture is preventing unnecessary costs and maintaining cost-effectiveness, while Performance Efficiency deals with selecting the right resources, efficient usage, and maintaining performance as requirements change.
