Question 50

A data science team requires storage for nightly log processing. The size and number of logs is unknown and will persist for 24 hours only.What is the MOST cost-effective solution?




The S3 Intelligent-Tiering storage class is designed to optimize costs by automatically moving data to the most cost-effective access tier, without performance impact or operational overhead. It works by storing objects in two access tiers: one tier that is optimized for frequent access and another lower-cost tier that is optimized for infrequent access. For a small monthly monitoring and automation fee per object, Amazon S3 monitors access patterns of the objects in S3 Intelligent-Tiering, and moves the ones that have not been accessed for 30 consecutive days to the infrequent access tier. If an object in the infrequent access tier is accessed, it is automatically moved back to the frequent access tier. There are no retrieval fees when using the S3 Intelligent-Tiering storage class, and no additional tiering fees when objects are moved between access tiers. It is the ideal storage class for long-lived data with access patterns that are unknown or unpredictable. S3 Storage Classes can be configured at the object level and a single bucket can contain objects stored in S3 Standard, S3 Intelligent-Tiering, S3 Standard-IA, and S3 One Zone-IA. You can upload objects directly to S3 Intelligent-Tiering, or use S3 Lifecycle policies to transfer objects from S3 Standard and S3 Standard-IA to S3 Intelligent-Tiering. You can also archive objects from S3 Intelligent-Tiering to S3 Glacier.
