Final answer:
S3 Intelligent-Tiering is best for uncertain access and low admin overhead, as it automatically optimizes costs by moving data between access tiers based on usage patterns.
Step-by-step explanation:
Comparison of S3 Storage Classes
When considering storage options in AWS S3 for scenarios with uncertain access patterns and a preference for low administrative overhead, S3 Intelligent-Tiering is the ideal choice. Unlike S3 Standard, which is better for frequently accessed data, or S3 One Zone-IA, which is cost-effective for infrequently accessed data but has lower durability as it is stored in a single AZ (Availability Zone), S3 Intelligent-Tiering automatically moves objects between different access tiers based on how frequently they are accessed. This helps to save costs without any administrative effort to analyze and change storage classes. S3 Glacier is intended for long-term archiving where retrieval times of several hours are acceptable, which is not suitable here.
S3 Intelligent-Tiering is the best of both worlds, offering cost savings for data with unpredictable access patterns, without compromising on data retrieval times. It's designed for data that has changing or unknown access patterns, making it a good fit for environments where it's difficult to predict when data will be accessed.
