What is Elastic Block Store (EBS): Definition & Importance
What is Elastic Block Store (EBS)
Elastic Block Store (EBS) is a cloud-based storage service provided by Amazon Web Services (AWS) that allows users to create and attach persistent block storage volumes to their Amazon Elastic Compute Cloud (EC2) instances.
EBS volumes can be used as primary storage for running applications or for storing data that needs to persist even after the instance is terminated. EBS volumes are highly available and durable, with data being replicated within a single Availability Zone (AZ) or across multiple AZs for added resilience.
EBS volumes can be easily created, attached, and detached from EC2 instances, and they can be resized on-the-fly without any downtime. This makes it easy for users to scale their storage requirements up or down as needed, and pay only for the storage they actually use.
In summary, EBS is a reliable, scalable, and flexible block storage solution that provides persistent storage for EC2 instances in the cloud.
