Durability and lifecycle tiering in Amazon S3 object storage
S3 essentials: object storage / eleven nines of high durability with redundancy / effectively unlimited capacity / automatic tiering via lifecycle. Block storage for an OS disk is EBS.
S3 Lifecycle policies that transition and expire objects by age
'Tier transition and deletion by age' points to the S3 lifecycle policy. Versioning (version management), replication (copying), and static hosting (delivery) have different purposes.
Choosing among Amazon EBS, Amazon S3, and Amazon EFS
'Attaches to EC2', 'disk', and 'block storage' point to Amazon EBS. Objects are S3, and a file system shared by multiple EC2 instances is EFS — distinguish them by type.
Amazon Lightsail for small workloads at a fixed monthly price
'Easy', 'fixed monthly price', and 'beginner/small' point to Amazon Lightsail. Advanced container platforms are EKS/ECS, functions are Lambda, and for fine control use EC2 — separate them by use case.
Amazon EventBridge routing events with rules
'Routes events by rules' and 'event bus' point to Amazon EventBridge. Simple one-to-many broadcast is SNS, and ordered message processing is SQS — use them accordingly.
