Description: S3 Intelligent-Tiering is a feature of Amazon Web Services (AWS) that allows users to optimize data storage in their S3 (Simple Storage Service). This storage class automatically moves data between two access tiers based on access patterns. This means that if a set of data is frequently accessed, it can be stored in a faster, more expensive access tier, while data that is accessed less frequently can be moved to a more cost-effective access tier. This functionality not only helps reduce costs but also improves data management efficiency, allowing organizations to adapt to fluctuations in data usage without manual intervention. S3 Intelligent-Tiering is particularly useful for organizations handling large volumes of data that need a flexible and automated storage solution, ensuring that data is available when needed while optimizing operational expenses.
