what is amazon ebs

Amazon Elastic Block Store (Amazon EBS) is a block-level storage service provided by Amazon Web Services (AWS) that can be attached to Amazon Elastic Compute Cloud (EC2) instances. EBS volumes behave like raw, unformatted block devices and are well-suited for use as the primary storage for file systems, databases, or for any applications that require fine granular updates and access to raw, unformatted, block-level storage. EBS volumes are particularly well-suited for use in database-style applications that rely on random reads and writes, and to throughput-intensive applications that perform long, continuous reads and writes. EBS volumes come in different types, including solid-state drives (SSD) and hard disk drives (HDD), and can be encrypted to meet data-at-rest encryption requirements. EBS-optimized instances are also available for an additional low, hourly fee, which deliver dedicated throughput between Amazon EC2 and Amazon EBS, providing the best performance for EBS volumes.
