Amazon S3 or Simple Storage Service provides object storage through a web interface. It enables users to store and retrieve any amount of data safely and its easy-to-use management features help you easily organize your data. This service is being used in many use cases such as websites, mobile applications, backup and restore, archive, enterprise applications, IoT devices, and big data analytics.
Amazon S3 Intelligent Tiering for automatic cost optimization
Amazon S3 comes with different storage classes designed for different use cases. The storage classes supported by S3 are Standard, Standard-IA, One Zone-IA, and Glacier. In addition to these, Amazon has added S3 Intelligent Tiering storage class, which is meant for automatically optimizing storage costs when data access patterns change. It consists of two tiers, namely, frequent access and infrequent access. It helps you cut the cost by monitoring your access patterns and moving the data that have not been accessed for consecutive 30 days to the infrequent tier. This object is moved back to the frequent access tier when accessed later.

Amazon S3 Object Lock to prevent object version deletion for a customer-defined retention period
Amazon S3 Object Lock is a new feature to allow customers store objects using the write-once-read-many (WORM) model. With this feature, you will be able to prevent the object from being deleted or overwritten for a fixed amount of time or indefinitely. This feature is currently in preview and generally available in all AWS Regions and AWS GovCloud (US) Regions.
S3 Object Lock comes with two mechanisms to manage object retention: retention periods and legal holds. A retention period is a fixed period of time during which your object will be WORM protected and can’t be deleted or overwritten. A legal hold is the same as the retention period but with no expiration date. An object version can have both a retention period and a legal hold.

This feature will be available in all AWS commercial and AWS GovCloud (US) Regions.
