Amazon S3 November 2019 Update

Released on November 20th, 2019

Amazon S3 Replication Time Control for Predictable Replication Time, Backed by an SLA

Amazon S3 Replication Time Control (S3 RTC) is a new feature of S3 Replication that provides a predictable replication time backed by a Service Level Agreement (SLA). S3 RTC helps customers meet compliance or business requirements for data replication, and provides visibility into the replication process with new Amazon CloudWatch Metrics.

Customers use S3 Replication to replicate billions of objects across buckets to the same or different regions. S3 Replication Time Control is designed to replicate 99.99% of objects within 15 minutes after upload, with the majority of those new objects replicated in seconds. S3 RTC is backed by an SLA with a commitment to replicate 99.9% of objects within 15 minutes during any billing month. S3 RTC also provides S3 Replication metrics (via CloudWatch) that allow customers to monitor the time it takes to complete replication, as well as the total number and size of objects that are pending replication.

Amazon S3 Replication Time Control is available in all commercial AWS Regions, excluding the AWS China (Beijing) Region and the AWS China (Ningxia) Region. S3 RTC can be configured through the S3 Management Console, SDK, or API. For pricing information, please visit the Amazon S3 pricing page. For more information on the S3 Replication Time Control SLA, please visit the S3 RTC SLA page.

To get started, read about Amazon S3 Replication Time Control on the AWS news blog, in the documentation, on the replication web page or in the S3 Replication FAQs

Amazon S3 Inventory Now Reports the Intelligent-tiering Access Tier for Objects 

Customers can now use Amazon S3 Inventory to report the access tier of objects stored in the S3 Intelligent-Tiering storage class. S3 Intelligent-Tiering is a new storage class that makes it easy for developers and IT infrastructure managers to reduce costs on storage when access patterns change without sacrificing performance or availability. It works by storing objects in one of two access tiers: one tier that is optimized for Frequent access, and another lower-cost tier that is optimized for Infrequent access. You can now use S3 Inventory to view the access tier of your Intelligent-Tiering objects in all AWS Regions.  

Amazon S3 inventory is one of the tools Amazon S3 provides to help manage your storage. You can use it to audit and report on the status of your objects for business, compliance, and regulatory needs. Amazon S3 inventory provides comma-separated values (CSV), Apache optimized row columnar (ORC) or Apache Parquet (Parquet) output files that list your objects and their corresponding metadata on a daily or weekly basis for an S3 bucket or a shared prefix. Customers can now also report Intelligent-Tiering access tier as a metadata field in their inventory reports. This feature is introduced at no-charge. For more information on pricing please see Amazon S3 pricing.  

You can get started with S3 Inventory by using the S3 Management Console, API, CLI or SDK to set your Inventory configuration. To learn what else is included in Inventory reports please visit Amazon S3 Inventory.
