Standard-IA: Lower storage, retrieval fee; 30-day minimum. Good for rarely-accessed archives. Bad for unpredictable access—retrieval adds up. Min object 128KB for efficiency. Compare with Glacier for colder. SCALABILITY: Same as Standard....
This easy-level General/Other question appears frequently in data engineering interviews at companies like Capco. 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.
Standard-IA: Lower storage, retrieval fee; 30-day minimum. Good for rarely-accessed archives. Bad for unpredictable access—retrieval adds up. Min object 128KB for efficiency. Compare with Glacier for colder. SCALABILITY: Same as Standard. COST: Storage cheap; retrieval expensive—use lifecycle to IA after 30 days; Glacier for 90+ day cold.
