This easy-level Cloud/Tools question appears frequently in data engineering interviews at companies like Presidio. While less common, it tests deeper understanding that distinguishes strong candidates.
Start by clearly defining the core concept being asked about. Interviewers want to see that you understand the fundamentals before diving into implementation details. Structure your answer with a definition, then explain the practical application with a concise example.
Integration Runtime (IR): Compute infrastructure that executes ADF activities—data movement, transforms, and external calls. ADF is orchestration; IR is execution. Types: Azure IR (managed, cloud), Self-Hosted IR (on-prem), Azure-SSIS IR (SSIS). Why it matters: Every Copy activity, Data Flow, and external activity runs on an IR. IR choice determines where compute runs and what it can reach. Scalability: Azure IR auto-scales; SHIR scales by adding nodes. Cost: Azure IR pay-per-use; SHIR = VM cost. Best practice: Use Azure IR by default; SHIR only for on-prem; choose based on data location.
