- Tied to one availability zone
- Can only be attached to one instance in the same availability zone

25
Q

Amazon Elastic Block Store is recommended for

A
  • Quickly accessible data
  • Running a database on an instance
  • Long-term data storage
26
Q

EC2 Instance Store

A

An instance store is local storage that is physically attached to the host computer and cannot be removed.
- Storage on disks physically attached to an instance
- Faster with higher I/O speeds
- Storage is temporary since data loss occurs when the EC2 instance is stopped

27
Q

EC2 Instance Store is recommended for

A
  • Temporary storage needs
  • Data replicated across multiple instances
28
Q

Amazon Elastic File System (EFS)

A

EFS is a serverless network file system for sharing files.
- Linux
- More expensive than EBS
- Accessible across availability zones in the same region

29
Q

Amazon Elastic File System is recommended for

A
  • Main directories for business-critical apps
  • Lift-and-shift existing enterprise apps
30
Q

Storage Gateway

A

A hybrid storage service
- Connect on-prem and cloud data
- hybrid model

31
Q
