Quick Introduction to OpenEBSOpenEBS is the technology that offers

“Containerized storage for Containers”

Comparison AWS EBS & OpenEBS

Feature AWS EBS OpenEBS

Network Block Storage as a service

Yes No. This is a technology that can be used to build a service or platform like AWS EBS

Technology form factor Unknown Open Source

High Availability grade Five nines of availability Five nines of availability

Availability zones Yes Yes

Point in time Snapshots to S3

Yes Yes, to S3 or any S3 equivalent (locally hosted Minio for example)

Connectivity in AWS EBS (Optimized for Cloud service)

Login into AWS Console

Create an EBS volume

Attach to an instance

Format and put it to use by application

Connectivity in OpenEBS (Optimized for Container service)
