Ephemeral volume aws1/8/2024 ![]() The goal is to provide consistently low latency for I/O-intensive applications. General-purpose Amazon EBS storage decision treeįor context, a general-purpose storage decision tree for Amazon EBS looks like the following figure:ĪWS designed io2 Block Express to be a significant leap in performance over the previous generation. We also draw conclusions regarding appropriate use cases. In this blog post, we compare how the new EBS storage type compares against existing storage options from the performance point of view. This means you can now significantly simplify the overall architecture when you require enterprise-class IOPS and throughput performance in addition to durability and scale. Using io2 Block express, you can design single-volume storage subsystem that can scale up to 256,000 IOPS, 4,000 MB/s of throughput, and 64 TB per single volume in storage. We have great news – now there’s no need to compromise your cloud database experience! On July 19 2021, we announced general availability for a new storage class: Amazon io2 Block Express. In short, if your database system required more than 80 K IOPS or 2,375 MB/s of throughput, you had to give up many benefits that you love about Amazon EBS and the cloud in general. Imagine being a technical architect limited by two of the three requirements: performance, simplicity, or resiliency. This led to a compromise for database administrators (DBAs), because it required them to custom build high availability (HA), disaster recovery (DR) solutions similar to on-premises. These particular EC2 instance types definitely solve the performance demands but lack the availability, durability, flexibility, and scalability of EBS, not to mention the benefits of EBS snapshots. Until December 2020, with SQL Server workloads that required more than 80,000 IOPS or 2,375 MB/s of throughput, your only high-performance option was an NVMe-powered Amazon EC2 instance store. ![]() If you’ve tried to optimize Amazon EBS performance for your SQL Server workload before, you may have come across this blog post from late 2019. ![]()
