Amazon S3 now includes several new enhancements that provide you improved insight, flexibility, and control of your data:
- Delete Event Notifications: You can now configure event notifications to be sent when objects are deleted. Delete event notifications can be used to add logic within your application or with AWS Lambda to build triggers like a script to clean up associated assets or maintain a separate index of your Amazon S3 objects.
- Prefix and Suffix Event Notification Filters: You can now configure Amazon S3 buckets to selectively provide event notifications based on object name prefixes and suffixes. For example, you can choose to receive notifications on object names that start with "images/."
- Amazon CloudWatch Storage Metrics: You can now monitor and set alarms on your Amazon S3 storage usage through CloudWatch metrics. Supported metrics include total bytes for Standard Storage, total bytes for Reduced Redundancy Storage (RRS), and total number of objects for a given Amazon S3 bucket. These metrics will allow you to better understand your Amazon S3 usage. CloudWatch metrics are provided at no additional cost and monitoring and alarming is billed at CloudWatch rates.
You can immediately get started with these new features. For more information about these features, please read the AWS Blog and visit the following documentation: Event Notifications and CloudWatch Metrics.
