We launched the reminiscence optimized Amazon EC2 R6a cases in July 2022 powered by third Gen AMD EPYC (Milan) processors, operating at frequencies as much as three.6 GHz. Many purchasers who run workloads which are depending on x86 directions, similar to SAP, are searching for methods to optimize their cloud utilization. They’re benefiting from the compute alternative that EC2 presents.
At present, we’re asserting the final availability of recent reminiscence optimized Amazon EC2 R7a cases powered by 4th Gen AMD EPYC (Genoa) processors with a most frequency of three.7 GHz, which provide as much as 50 p.c larger efficiency in comparison with the earlier technology cases. You need to use this elevated efficiency to course of knowledge sooner, consolidate workloads, and decrease the price of possession.
R7a cases additionally help AVX-512, Vector Neural Community Directions (VNNI), and mind floating level (bfloat16). These cases function Double Information Charge 5 (DDR5) reminiscence, which allows high-speed entry to knowledge in-memory, and ship 2.25 occasions extra reminiscence bandwidth in comparison with R6a cases for decrease latency. Furthermore, these cases help always-on reminiscence encryption utilizing AMD safe reminiscence encryption (SME).
These cases are SAP-certified and ultimate for top efficiency, memory-intensive workloads, similar to SQL and NoSQL databases, distributed net scale in-memory caches, in-memory databases, real-time large knowledge analytics, and Digital Design Automation (EDA) functions.
R7a cases function 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 | eight | As much as 12.5 | As much as 10 |
| r7a.giant | 2 | 16 | As much as 12.5 | As much as 10 |
| r7a.xlarge | four | 32 | As much as 12.5 | As much as 10 |
| r7a.2xlarge | eight | 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 cases have as much as 50 Gbps enhanced networking and 40 Gbps EBS bandwidth, which is analogous to R6a cases. You have got a brand new medium occasion dimension, which you should use to right-size your workloads extra precisely, providing 1 vCPUs, eight GiB. Moreover, with R7a cases you possibly can connect as much as 128 EBS volumes to an occasion in comparison with as much as 28 EBS quantity attachments with R6a cases. R7a cases help AES-256 in comparison with AES-128 in R6a cases for enhanced safety.
R7a cases are constructed on the AWS Nitro System and help Elastic Cloth Adapter (EFA) for workloads that profit from decrease community latency and extremely scalable inter-node communication, similar to high-performance computing and video processing.
Now Obtainable
Amazon EC2 R7a cases are actually out there in AWS Areas: US East (Ohio), US East (N. Virginia), US West (Oregon), and EU (Eire). As standard with Amazon EC2, you solely pay for what you employ. For extra data, see the Amazon EC2 pricing web page.
To study extra, go to the EC2 R7a cases web page, and AWS/AMD companion web page. You’ll be able to ship suggestions to ec2-amd-customer-feedback@amazon.com, AWS re:Submit for EC2, or via your standard AWS Assist contacts.
