Identifying the uses for object storage
Automate snapshots and backups based on use cases (for example, RDS snapshots, AWS Backup, RTO and RPO, Amazon Data Lifecycle Manager, retention policy).
Recognizing the differences in Amazon S3 storage classes
Restore databases (for example, point-in-time restore, promote read replica).
Identifying block storage solutions (for example, Amazon Elastic Block Store [Amazon EBS], instance store)
Serverless technologies and patterns (for example, Lambda, Fargate)
Identifying file services (for example, Amazon Elastic File System [Amazon EFS], Amazon FSx)
Implement versioning and lifecycle rules.
The orchestration of containers (for example, Amazon ECS, Amazon EKS)
Data structures and algorithms (for example, graph data structures and tree data structures)
Identifying cached file systems (for example, AWS Storage Gateway)
Configure Amazon S3 Cross-Region Replication (CRR).
Understanding use cases for lifecycle policies
AWS global infrastructure (for example, Availability Zones, AWS Regions)
