EBS – AWS’s block storage service.
EBS provides persistent block-level storage volumes for EC2 instances. It offers different volume types (General Purpose SSD, Provisioned IOPS SSD, Throughput Optimized HDD, Cold HDD) optimized for different workloads. EBS volumes can be resized, encrypted, and backed up through snapshots. They provide consistent low-latency performance and are automatically replicated within their Availability Zone. EBS volumes can be attached to and detached from EC2 instances, and their snapshots can be shared across AWS accounts or copied across regions.
