Amazon S3 Object Lambda allows you to add your own code to process data retrieved from S3 before it is returned to an application. You can use this to dynamically redact or remove PII for specific applications on-the-fly, eliminating the need to manage multiple buckets or datasets, thus minimizing operational overhead.

Reference Extract:

" S3 Object Lambda enables you to process and transform data as it is retrieved from S3, supporting use cases such as redacting sensitive information before returning data to an application. "

AWS Backup is a fully managed backup service designed to centralize and automate data protection across AWS services including EC2 and RDS. It allows users to define backup schedules (backup plans) and automatically create and retain backups. AWS Backup also offers restore testing plans, allowing users to automate the validation of backups by restoring them in a controlled manner. This service is built to minimize operational overhead by removing the need to manage custom scripts, manual processes, or additional orchestration services. This aligns with AWS best practices for resilience, automation, and operational excellence.

Reference Extract from AWS Documentation / Study Guide:

" AWS Backup enables you to centralize and automate data protection across AWS services. You can create backup plans, schedule backups, and set lifecycle policies. AWS Backup also enables restore testing to verify your backup integrity, with minimal manual intervention. "

Amazon FSx for Lustre is the correct storage service for high-throughput training workloads that must feed multiple GPU instances quickly. SageMaker can use FSx for Lustre as a training data source to reduce data-loading time and improve training throughput. FSx for Lustre also integrates with Amazon S3 through data repository associations, allowing the large image dataset to be linked from S3 and presented through a high-performance Lustre file system. Standard S3 file mode can create data-loading bottlenecks for very large training jobs. Fast file mode improves S3 access, but the requirement for tens of Gbps and avoiding expensive GPU idle time points more strongly to FSx for Lustre. Glacier Flexible Retrieval is inappropriate for active training data.
