Amazon Elastic Block Store (Amazon EBS) provides persistent block level storage volumes for use with Amazon EC2 instances. In this technical session, we conduct a detailed analysis of the differences among the three types of Amazon EBS block storage: General Purpose (SSD), Provisioned IOPS (SSD), and Magnetic. We discuss how to maximize Amazon EBS performance, with a special eye towards low-latency, high-throughput applications like databases. We discuss the performance implications of our new larger and faster SSD volumes (up to 16 TB with increased max throughput levels), as well as Amazon EBS encryption. Throughout, we share tips for success.
