  • Amazon FSx: Fully managed file servers (Windows, Lustre, NetApp ONTAP).

Storage Types​

  • Object Storage: S3, Glacier - Store and retrieve data as objects
  • Block Storage: EBS - Like traditional hard drives, attached to EC2
  • File Storage: EFS, FSx - Shared file systems accessible by multiple instances
  • Hybrid Storage: Storage Gateway - Connect on-premises storage to AWS

Key Considerations​

  • Durability: How reliable the storage is (e.g., S3 offers 99.999999999% durability)
  • Availability: How accessible the data is
  • Performance: Speed of data access and throughput
  • Cost: Pricing models vary by service and usage patterns

Choose the right storage service based on your application's requirements for access patterns, performance, and cost.
