Production Environment Architecture Questions

Design and rationale of production infrastructure and how components integrate to support applications. Topics include compute and storage choices and redundancy patterns, networking and traffic management including load balancing and routing, service discovery and dependency management, deployment architectures and release strategies such as blue green and canary deployments, observability and logging pipelines, security boundaries and network segmentation, backup and recovery strategies, and runbook driven operational procedures. Interviewers may ask candidates to draw architecture diagrams and justify tradeoffs for availability scalability and cost.
