We launched the reminiscence optimized Amazon EC2 R6a situations in July 2022 powered by third Gen AMD EPYC (Milan) processors, working at frequencies as much as 3.6 GHz. Many shoppers who run workloads which might be depending on x86 directions, equivalent to SAP, are in search of methods to optimize their cloud utilization. They’re profiting from the compute selection that EC2 presents.
As we speak, we’re saying the final availability of latest reminiscence optimized Amazon EC2 R7a situations powered by 4th Gen AMD EPYC (Genoa) processors with a most frequency of three.7 GHz, which provide as much as 50 p.c greater efficiency in comparison with the earlier technology situations. You should use this elevated efficiency to course of knowledge sooner, consolidate workloads, and decrease the price of possession.
R7a situations additionally help AVX-512, Vector Neural Community Directions (VNNI), and mind floating level (bfloat16). These situations characteristic Double Information Fee 5 (DDR5) reminiscence, which permits high-speed entry to knowledge in-memory, and ship 2.25 instances extra reminiscence bandwidth in comparison with R6a situations for decrease latency. Furthermore, these situations help always-on reminiscence encryption utilizing AMD safe reminiscence encryption (SME).
These situations are SAP-certified and perfect for top efficiency, memory-intensive workloads, equivalent to SQL and NoSQL databases, distributed net scale in-memory caches, in-memory databases, real-time massive knowledge analytics, and Digital Design Automation (EDA) purposes.
R7a situations characteristic sizes of as much as 192 vCPUs with 1536 GiB RAM. Listed below are the detailed specs:
| Title | vCPUs | Reminiscence (GiB) | Community Bandwidth (Gbps) | EBS Bandwidth (Gbps) |
| r7a.medium | 1 | 8 | As much as 12.5 | As much as 10 |
| r7a.massive | 2 | 16 | As much as 12.5 | As much as 10 |
| r7a.xlarge | 4 | 32 | As much as 12.5 | As much as 10 |
| r7a.2xlarge | 8 | 64 | As much as 12.5 | As much as 10 |
| r7a.4xlarge | 16 | 128 | As much as 12.5 | As much as 10 |
| r7a.8xlarge | 32 | 256 | 12.5 | 10 |
| r7a.12xlarge | 48 | 384 | 18.75 | 15 |
| r7a.16xlarge | 64 | 512 | 25 | 20 |
| r7a.24xlarge | 96 | 768 | 37.5 | 30 |
| r7a.32xlarge | 128 | 1024 | 50 | 40 |
| r7a.48xlarge | 192 | 1536 | 50 | 40 |
R7a situations have as much as 50 Gbps enhanced networking and 40 Gbps EBS bandwidth, which has similarities to R6a situations. You may have a brand new medium occasion measurement, which you should use to right-size your workloads extra precisely, providing 1 vCPUs, 8 GiB. Moreover, with R7a situations you’ll be able to connect as much as 128 EBS volumes to an occasion in comparison with as much as 28 EBS quantity attachments with R6a situations. R7a situations help AES-256 in comparison with AES-128 in R6a situations for enhanced safety.
R7a situations are constructed on the AWS Nitro System and help Elastic Material Adapter (EFA) for workloads that profit from decrease community latency and extremely scalable inter-node communication, equivalent to high-performance computing and video processing.
Now Out there
Amazon EC2 R7a situations are actually out there in AWS Areas: US East (Ohio), US East (N. Virginia), US West (Oregon), and EU (Eire). As normal with Amazon EC2, you solely pay for what you utilize. For extra info, see the Amazon EC2 pricing web page.
To study extra, go to the EC2 R7a situations web page, and AWS/AMD accomplice web page. You may ship suggestions to ec2-amd-customer-feedback@amazon.com, AWS re:Put up for EC2, or by means of your normal AWS Assist contacts.
