re:Invent 2020 (30 November to 18 December) was fully online. Four changes that affect daily work:
| Announcement | Why it matters |
|---|---|
| S3 strong read-after-write consistency (1 December) | Overwrites and deletes are visible immediately, so workarounds for eventual consistency can be removed |
| EBS gp3 volumes (1 December) | Baseline 3,000 IOPS and 125 MiB/s independent of size, about 20 percent cheaper per GB than gp2 |
| Lambda container images (1 December) | Package functions as images up to 10 GB, and Lambda bills per millisecond |
| Amazon ECR public (preview) | A public registry on AWS that can serve as an alternative to Docker Hub |
Try gp3 on a non-critical volume:
aws ec2 modify-volume --volume-id vol-0abc123 --volume-type gp3 --region ap-south-1
Volumes change type in place without detaching. Also in preview: Amazon Managed Service for Prometheus and Amazon Managed Grafana. Treat previews as non-production until they reach general availability.
