Amazon Elastic Block Store is a block-storage service that is easy to use and high-performance. It can be used with Amazon Elastic Compute Cloud, (EC2), for transaction-intensive workloads of any size. Amazon EBS is widely used for a wide range of workloads such as enterprise applications, relational and nonrelational databases, big data analytics engines, file system, and media workflows. To balance price and performance, you can choose from six volume types. You can achieve single-digit-millisecond latency for high-performance database workloads such as SAP HANA or gigabyte per second throughput for large, sequential workloads such as Hadoop. You can modify volume types, tune performance or increase volume size without affecting your critical applications so that you have cost-effective storage whenever you need it.
