Right now, we’re asserting normal availability of the brand new eighth era, reminiscence optimized Amazon Elastic Compute Cloud (Amazon EC2) R8i and R8i-flex situations powered by customized Intel Xeon 6 processors, out there solely on AWS. They ship the best efficiency and quickest reminiscence bandwidth amongst comparable Intel processors within the cloud. These situations ship as much as 15 % higher worth efficiency, 20 % larger efficiency, and a couple of.5 instances extra reminiscence throughput in comparison with earlier era situations.
With these enhancements, R8i and R8i-flex situations are perfect for quite a lot of reminiscence intensive workloads corresponding to SQL and NoSQL databases, distributed net scale in-memory caches (Memcached and Redis), in-memory databases corresponding to SAP HANA, and real-time massive knowledge 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 situations are an amazing first selection to attain an extra 5 % higher worth efficiency and 5 % decrease costs.
Enhancements made to each situations in comparison with their predecessors
When it comes to efficiency, R8i and R8i-flex situations supply 20 % higher efficiency than R7i situations, with even larger positive factors for particular workloads. These situations are as much as 30 % quicker for PostgreSQL databases, as much as 60 % quicker for NGINX net functions, and as much as 40 % quicker for AI deep studying advice fashions in comparison with earlier era R7i situations, with sustained all-core turbo frequency now reaching 3.9 GHz (in comparison with 3.2 GHz within the earlier era). Additionally they characteristic a 4.6x bigger L3 cache and considerably higher reminiscence throughput, providing 2.5 instances larger reminiscence bandwidth than the seventh era. With this larger efficiency throughout all of the vectors, you’ll be able to run a better variety of workloads whereas conserving prices down.
R8i situations now scale as much as 96xlarge with as much as 384 vCPUs and 3TB reminiscence (versus 48xlarge sizes within the seventh era), serving to you to scale up database functions. R8i situations 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 situations supply the most typical sizes, from massive to 16xlarge, and are an amazing first selection for functions that don’t absolutely make the most of all compute sources. Each R8i and R8i-flex situations use the newest sixth era AWS Nitro Playing cards, delivering as much as two instances extra community and Amazon Elastic Block Storage (Amazon EBS) bandwidth in comparison with the earlier era, which tremendously improves community throughput for workloads dealing with small packets, corresponding to net, software, and gaming servers.
R8i and R8i-flex situations additionally assist bandwidth configuration with 25 % allocation changes between community and Amazon EBS bandwidth, enabling higher database efficiency, question processing, and logging speeds. Extra enhancements embrace FP16 datatype assist for Intel AMX to assist workloads corresponding to deep studying coaching and inference and different synthetic intelligence and machine studying (AI/ML) functions.
The specs for the R8i situations are as follows.

When to make use of the R8i-flex situations
As acknowledged earlier, R8i-flex situations are extra reasonably priced variations of the R8i situations, providing as much as 5 % higher worth efficiency at 5 % decrease costs. They’re designed for workloads that profit from the newest era efficiency however don’t absolutely use all compute sources. These situations can attain as much as the total CPU efficiency 95 % of the time and work nicely for in-memory databases, distributed net scale cache shops, mid-size in-memory analytics, real-time massive knowledge analytics, and different enterprise functions. R8i situations are beneficial for extra demanding workloads that want sustained excessive CPU, community, or EBS efficiency corresponding to analytics, databases, enterprise functions, and net scale in-memory caches.
