Amazon Elastic Block Store

It's great for unstructured data, backups, and static content.

Block storage is EBS, which attaches to a single EC2 instance like a virtual hard drive for operating systems and databases.

And file storage is EFS and FSX.

It's shared file systems that you can mount from multiple instances.

Then there is Glacier Tiers for archiving, Glacier Instant Retrieval for archives needing immediate access and Glacier Flexible Retrieval for minutes to hours retrieval and finally Glacier Deep Archive the cheapest for the data you rarely touch with retrieval in hours.

And S3 Intelligent Tiering automatically moves objects between these tiers based on usage with no retrieval fees for unknown or changing access patterns.

Next, we have EBS volume types, general purpose SSD, the GP2 and GP3 types.

They balance price and performance for most workloads.

This is essentially a giant, incredibly fast hard drive array connected directly to the servers via high-speed fiber channel cables.

In AWS, that translates to Elastic Block Store, or EBS.

And in Kubernetes?

When you request a persistent volume using the GP3-CSI driver, you are asking for EBS.

It is raw block level storage that acts exactly like an unformatted hard drive plugged into your machine.

And the other common physical storage is a NAS, network attached storage, or an NFS file server.

It just does it on the fly.

Yeah.
