IT 4100 : File Systems and Storage Technologies

Cloud - EFS

Cloud Storage - EFS

• Amazon EFS implements storage for EC2 instances that multiple virtual machines can access at the same time. It is implemented as a shared fil e system that uses the Network File System (NFS) protocol.
• Grows and shrinks automatically as you add/remove files.
• can be used with on-premises resources

Cloud Storage - EFS

• Use cases: big data and analytics, content management, web serving, home directories.
• As long as instances are in the same region
• Uses a traditional file permissions model, file-locking capabilities, and hierarchical directory structure using the NFSv4 protocol.

Cloud Storage - EFS

• Overview

Standard storage classes store data within and across multiple availability zones (AZ). One Zone storage classes store data redundantly within a single AZ, at a 47% lower price compared to file systems using Standard storage classes, for workloads that don’t require multi-AZ resilience.

Cloud Storage - EFS

• Posix-compliant file storage
  • means we can use traditional file permissions model (chmod, chown)
• file-locking
• hierarchy (via NFSv4 protocol)

Cloud Storage - EFS

• See this case study.

Cloud Storage - EFS

• Can connect to on-prem site
• Demo time!
