Amazon Web Services (AWS) announces the availability of Amazon EC2 R5b instances that can utilize up to 60 Gbps of Amazon Elastic Block Storage (EBS) bandwidth and 260 IOPS (I/O operations per second) for large relational database workloads. These instances offer significantly higher EBS performance across all instance sizes, ranging from 10 Gbps of EBS bandwidth on smaller instance sizes to 60 Gbps of EBS bandwidth on the largest instance size. R5b instances are powered by custom second-generation Intel® Xeon® Scalable processors (Cascade Lake) with sustained all-core turbo frequency of 3.1 GHz. These new instances are designed for workloads such as relational databases and File systems that can take advantage of improved EBS bandwidth and IOPS.
