Episode notes
Cryptographic EC2 Attestation Is Available
- EC2 Instance Attestation lets you cryptographically verify an EC2 instance is running trusted software and configuration.
- It uses the Nitro TPM and testable AMIs and integrates with KMS at no extra cost in commercial and GovCloud regions.
Use Conditional Deletes To Prevent Accidental Loss
- Use S3 conditional deletes to prevent accidental removals in high-concurrency, multi-writer scenarios.
- Require matching ETags or use the If-Match condition in bucket policies to ensure you delete the exact object version you intend.
OpenSearch Improves Vector Efficiency
- OpenSearch v3.1 and Lucene 10 improve vector indexing, search relevance, and reduce index size.
- New disk-optimized vector storage trades slightly higher latency for much lower cost while preserving accuracy and recall.
