The AWS Nitro System is the underlying platform for the latest generation of EC2 instances that enables AWS to innovate faster, further reduce cost for our customers, and deliver added benefits like increased security and new instance types. With the latest set of enhancements to the Nitro system, all new C5/C5d/C5n, M5/M5d/M5n/M5dn, R5/R5d/R5n/R5dn, and P3dn instances now support 36% higher EBS-optimized instance bandwidth, up to 19 Gbps. Also, 6, 9, and 12 TB Amazon EC2 High Memory instances can now support 19 Gbps of EBS-optimized instance bandwidth, a 36% increase from 14 Gbps. 

This performance increase enables you to speed up sections of your workflows dependent on EBS-optimized instance performance. For storage intensive workloads, you will have an opportunity to use smaller instance sizes and still meet your EBS-optimized instance performance requirement, thereby saving costs. With this performance increase, you will be able to handle unplanned spikes in EBS-optimized instance demand without any impact to your application performance. 

All new C5/C5d/C5n, M5/M5d/M5n/M5dn, R5/R5d/R5n/R5dn, P3dn, and High Memory instances (6, 9, 12 TB) starting today will be able to take advantage of this performance increase at no additional cost. For details on the performance increase for each instance size, please refer here
