AWS Storage Gateway Expands Automation with New CloudWatch Event, and Support for "Requester Pays" Buckets
The AWS Storage Gateway service expanded the set of CloudWatch Events for File Gateway to help automate hybrid cloud workflows, and now supports "Requester Pays" Amazon S3 buckets.
File Gateway enables on-premises applications to access objects in S3 as files. File contents and metadata are cached locally for optimal performance. The refresh cache operation synchronizes the local cache with S3. The new Amazon CloudWatch Event occurs when a refresh cache operation finishes. Combined with file upload notification events, it enables you to automate workflows for data processing and content sharing in a hybrid cloud architecture.
File Gateway can now access S3 buckets configured as "Requester Pays". Typically, bucket owners pay the cost of downloading data, but with "Requester Pays" enabled, the requester pays for requests and data downloads. Such buckets can be used to share public data, such as Hubble Space Telescope observations, or USDA Aerial Photography. File Gateway caches frequently used data locally, helping requesters to reduce latency and costs.
File Gateway appliances can now also run on Amazon EC2 C5/M5 instances, and support predefined cross-account bucket access using Amazon S3 Canned Access Control Lists (ACLs).
New File Gateway appliances contain these features, and existing File Gateways will receive them automatically in the next scheduled maintenance update. You can apply the update manually through the management console or service API.
