# EBS

***

#### EBS (Elastic Block Store)

* What it is: Block Storage. Think of this as the "Hard Drive" (C: drive) plugged into your EC2 server. It is fast and meant for the operating system and installed software. If you stop the server, the data on EBS persists.
  * *Constraint:* An EBS volume can usually only be attached to one EC2 instance at a time.
* Equivalents:
  * GCP: Persistent Disk
  * Azure: Azure Disk Storage (Managed Disks)
