1. S3 Object Tagging – With S3 Object Tagging you can manage and control access for Amazon S3 objects. S3 Object Tags are key-value pairs applied to S3 objects which can be created, updated or deleted at any time during the lifetime of the object. With these, you’ll have the ability to create Identity and Access Management (IAM) policies, setup S3 Lifecycle policies, and customize storage metrics. These object-level tags can then manage transitions between storage classes and expire objects in the background.
2. S3 Analytics, Storage Class Analysis – With storage class analysis, you can analyze storage access patterns and transition the right data to the right storage class. This new S3
3. Analytics feature automatically identifies the optimal lifecycle policy to transition less frequently accessed storage to SIA. You can configure a storage class analysis policy to monitor an entire bucket, a prefix, or object tag. Once an infrequent access pattern is observed, you can easily create a new lifecycle age policy based on the results. Storage class analysis also provides daily visualizations of your storage usage in the AWS Management Console. You can export these to an S3 bucket to analyze using the business intelligence tools of your choice, such as Amazon QuickSight. S3 Inventory – You can simplify and speed up business workflows and big data jobs using S3 Inventory, which provides a scheduled alternative to Amazon S3’s synchronous List API. S3 Inventory provides a CSV (Comma Separated Values) flat- file output of your objects and their corresponding metadata on a daily or weekly basis for an S3 bucket or a shared prefix.
4. S3 CloudWatch Metrics – Understand and improve the performance of your applications that use Amazon S3 by monitoring and alarming on 13 new S3 CloudWatch Metrics. You can receive 1-minute CloudWatch Metrics, set CloudWatch alarms, and access CloudWatch dashboards to view real-time
5. operations and performance such as bytes downloaded and the

   4xx HTTP response count of your Amazon S3 storage. For web and mobile applications that depend on cloud storage, these let you quickly identify and act on operational issues. By default, 1- minute metrics are available at the S3 bucket level. You also have the flexibility to define a filter for the metrics collected using a shared prefix or object tag, allowing you to align metrics to specific business applications, workflows, or internal organizations.
