The query is essentially a litmus test to gauge your hands-on experience with AWS-based applications. This question also sheds light on your problem-solving skills and ability to enhance system efficiency, both of which are critical in the role of a Cloud DevOps Engineer. As a cloud DevOps engineer, you’re the custodian of your company’s cloud infrastructure, and that includes safeguarding the data stored therein.

By asking this question, interviewers want to gauge your hands-on experience and ability to analyze and act upon the insights provided by these tools. This question is asked to evaluate your technical understanding of AWS and its features, particularly auto-scaling. Auto-scaling is a key aspect of cloud computing that allows businesses to optimize resource usage and minimize costs.

Infrastructure as a service (IaaS) provides computing resources such as servers, storage, and networking over the internet. Customers have control over the operating systems, storage, and deployed applications that run on infrastructure — but the provider manages the underlying infrastructure.

The interviewer wants to understand your expertise in managing and executing this process. They are interested in how you strategize, plan, and implement data migration, which can be a complex and impactful task. They also want to gauge your knowledge of AWS services and tools used for such processes.
