Q

Block Storage

Examples

A

dedicated, low latency storage for each host

Raw storage. Data organized as
an array of unrelated blocks.

This storage is similar to direct attached storage (DAS) or a
storage area network (SAN).

Block based cloud storage are provisioned with each virtual server and offer the ultra low latency required for high performance
workloads.

Examples:
hard disk, storage
area network (SAN), storage
arrays, EBS

Q

File storage

Examples

A

Unrelated data blocks managed by a file serving system. Native file system places data on disk

Examples: Network Attached Storage (NAS) appliances, Windows File servers, EFS, FSx

Q

Amazon
EFS

A

Amazon EFS provides a scalable, elastic file system for Linux based workloads for use with AWS Cloud services and on premises resources.

You can create a file system, mount it on an Amazon EC2 instance, and then read and write data to and from
your file system. You can mount an Amazon EFS file system in your VPC through the Network File System (NFS) versions 4.0 and 4.1 (NFSv4) protocol. You do not need to take action to expand the file system as your storage needs grow.
EC2 instances in your VPC can access Amazon EFS file systems concurrently, so applications that scale beyond a single connection can access a file system.

Q

Amazon EFS Availability & Durability

A

Availability and durability refer to the redundancy with which an Amazon EFS file system stores data within an
AWS Region. You have the following choices for your file system’s availability and durability:
*
Standard storage - creates a file system that stores file system data and metadata redundantly
across all Availability Zones within an AWS Region
*
One Zone storage class - lass creates a file system that stores file system data and metadata
redundantly within a single Availability Zone - only allowed a single mount target

Q

EFS Benefits

A

Scale throughput based on storage use or provision throughput independent of storage

Automatically grows and shrinks storage without provisioning

Managed services so lower total cost of ownership (TCO)
