Devops Interview Questions

13,115 devops interview questions shared by candidates

Case Study: There are multiple platforms operating across AWS, Azure, and a legacy hosted datacenter. The organization is under pressure from the board and investors to improve operating leverage by reducing infrastructure costs by at least 20% without sacrificing reliability, security, or customer experience. The AWS and Azure environment includes a large footprint of instances and under-optimized storage. Meanwhile, a hosted datacenter continues to house legacy workloads, with a colocation contract extending another 18 months and aging hardware nearing replacement. This hybrid reality creates complexity, inefficiency, and risk. You’ll have one week to prepare, and the final session will be a 60-minute interactive presentation where you’ll share your insights and plan. This exercise is intended to remain high level—it is not about detailed implementation specifics but rather about how you think through challenges, set priorities, and drive transformation. The goal is to facilitate discussion, surface your ideas, and understand how you approach cost management, trade-offs, and executive communication."
