Today, we’re saying common availability of the brand new eighth technology, reminiscence optimized Amazon Elastic Compute Cloud (Amazon EC2) R8i and R8i-flex cases powered by customized Intel Xeon 6 processors, accessible solely on AWS. They ship the best efficiency and quickest reminiscence bandwidth amongst comparable Intel processors within the cloud. These cases ship as much as 15 % higher worth efficiency, 20 % larger efficiency, and a couple of.5 instances extra reminiscence throughput in comparison with earlier technology cases.
With these enhancements, R8i and R8i-flex cases are perfect for a wide range of reminiscence intensive workloads resembling SQL and NoSQL databases, distributed internet scale in-memory caches (Memcached and Redis), in-memory databases resembling SAP HANA, and real-time huge information analytics (Apache Hadoop and Apache Spark clusters). For a majority of the workloads that don’t absolutely make the most of the compute sources, the R8i-flex cases are an incredible first alternative to attain an extra 5 % higher worth efficiency and 5 % decrease costs.
Improvements made to each cases in comparison with their predecessors
In phrases of efficiency, R8i and R8i-flex cases provide 20 % higher efficiency than R7i cases, with even larger beneficial properties for particular workloads. These cases are as much as 30 % quicker for PostgreSQL databases, as much as 60 % quicker for NGINX internet purposes, and as much as 40 % quicker for AI deep studying suggestion fashions in comparison with earlier technology R7i cases, with sustained all-core turbo frequency now reaching 3.9 GHz (in comparison with 3.2 GHz within the earlier technology). They additionally function a 4.6x bigger L3 cache and considerably higher reminiscence throughput, providing 2.5 instances larger reminiscence bandwidth than the seventh technology. With this larger efficiency throughout all of the vectors, you possibly can run a higher variety of workloads whereas retaining prices down.
R8i cases now scale as much as 96xlarge with as much as 384 vCPUs and 3TB reminiscence (versus 48xlarge sizes within the seventh technology), serving to you to scale up database purposes. R8i cases are SAP licensed to ship 142,100 aSAPS, which is highest amongst all comparable machines in on premises and cloud environments, delivering distinctive efficiency to your mission-critical SAP workloads. R8i-flex cases provide the commonest sizes, from giant to 16xlarge, and are an incredible first alternative for purposes that don’t absolutely make the most of all compute sources. Both R8i and R8i-flex cases use the newest sixth technology AWS Nitro Cards, delivering as much as two instances extra community and Amazon Elastic Block Storage (Amazon EBS) bandwidth in comparison with the earlier technology, which vastly improves community throughput for workloads dealing with small packets, resembling internet, utility, and gaming servers.
R8i and R8i-flex cases additionally help bandwidth configuration with 25 % allocation changes between community and Amazon EBS bandwidth, enabling higher database efficiency, question processing, and logging speeds. Additional enhancements embody FP16 datatype help for Intel AMX to help workloads resembling deep studying coaching and inference and different synthetic intelligence and machine studying (AI/ML) purposes.
The specs for the R8i cases are as follows.

When to make use of the R8i-flex cases
As acknowledged earlier, R8i-flex cases are extra reasonably priced variations of the R8i cases, providing as much as 5 % higher worth efficiency at 5 % decrease costs. They’re designed for workloads that profit from the newest technology efficiency however don’t absolutely use all compute sources. These cases can attain as much as the total CPU efficiency 95 % of the time and work effectively for in-memory databases, distributed internet scale cache shops, mid-size in-memory analytics, real-time huge information analytics, and different enterprise purposes. R8i cases are beneficial for extra demanding workloads that want sustained excessive CPU, community, or EBS efficiency resembling analytics, databases, enterprise purposes, and internet scale in-memory caches.
Available now
R8i and R8i-flex cases can be found in the present day within the US East (N. Virginia), US East (Ohio), US West (Oregon), and Europe (Spain) AWS Regions. As common with Amazon EC2, you pay just for what you utilize. For extra data, discuss with Amazon EC2 Pricing.
