After launching Amazon Elastic Compute Cloud (Amazon EC2) memory-optimized R8i and R8i-flex cases and general-purpose M8i and M8i-flex cases, I’m pleased to announce the overall availability of compute-optimized C8i and C8i-flex cases powered by customized Intel Xeon 6 processors obtainable solely on AWS with sustained all-core 3.9 GHz turbo frequency and have a 2:1 ratio of reminiscence to vCPU. These cases ship the very best efficiency and quickest reminiscence bandwidth amongst comparable Intel processors within the cloud.
The C8i and C8i-flex cases supply as much as 15 % higher price-performance, and a couple of.5 instances extra reminiscence bandwidth in comparison with C7i and C7i-flex cases. The C8i and C8i-flex cases are as much as 60 % quicker for NGINX internet purposes, as much as 40 % quicker for AI deep studying advice fashions, and 35 % quicker for Memcached shops in comparison with C7i and C7i-flex cases.
C8i and C8i-flex cases are perfect for working compute-intensive workloads, comparable to internet servers, caching, Apache.Kafka, ElasticSearch, batch processing, distributed analytics, excessive efficiency computing (HPC), advert serving, extremely scalable multiplayer gaming, and video encoding.
As like different eighth technology cases, these cases use the brand new sixth technology 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 technology cases. In addition they help bandwidth configuration with 25 % allocation changes between community and Amazon EBS bandwidth, enabling higher database efficiency, question processing, and logging speeds.
C8i cases
C8i cases present as much as 384 vCPUs and 768 TB reminiscence together with naked metallic cases that present devoted entry to the underlying bodily {hardware}. These cases enable you to run compute-intensive workloads, comparable to CPU-based inference, and video streaming that want the biggest occasion sizes or excessive CPU repeatedly.
Listed here are the specs for C8i cases:
| Occasion dimension | vCPUs | Reminiscence (GiB) | Community bandwidth (Gbps) | EBS bandwidth (Gbps) |
| c8i.massive | 2 | 4 | As much as 12.5 | As much as 10 |
| c8i.xlarge | 4 | 8 | As much as 12.5 | As much as 10 |
| c8i.2xlarge | 8 | 16 | As much as 15 | As much as 10 |
| c8i.4xlarge | 16 | 32 | As much as 15 | As much as 10 |
| c8i.8xlarge | 32 | 64 | 15 | 10 |
| c8i.12xlarge | 48 | 96 | 22.5 | 15 |
| c8i.16xlarge | 64 | 128 | 30 | 20 |
| c8i.24xlarge | 96 | 192 | 40 | 30 |
| c8i.32xlarge | 128 | 256 | 50 | 40 |
| c8i.48xlarge | 192 | 384 | 75 | 60 |
| c8i.96xlarge | 384 | 768 | 100 | 80 |
| c8i.metal-48xl | 192 | 384 | 75 | 60 |
| c8i.metal-96xl | 384 | 768 | 100 | 80 |
C8i-flex cases
C8i-flex cases are a lower-cost variant of the C8i cases, with 5 % higher value efficiency at 5 % decrease costs. These cases are designed for workloads that profit from the newest technology efficiency however don’t totally make the most of all compute assets. These cases can attain as much as the total CPU efficiency 95 % of the time.
Listed here are the specs for the C8i-flex cases:
| Occasion dimension | vCPUs | Reminiscence (GiB) | Community bandwidth (Gbps) | EBS bandwidth (Gbps) |
| c8i-flex.massive | 2 | 4 | As much as 12.5 | As much as 10 |
| c8i-flex.xlarge | 4 | 8 | As much as 12.5 | As much as 10 |
| c8i-flex.2xlarge | 8 | 16 | As much as 15 | As much as 10 |
| c8i-flex.4xlarge | 16 | 32 | As much as 15 | As much as 10 |
| c8i-flex.8xlarge | 32 | 64 | As much as 15 | As much as 10 |
| c8i-flex.12xlarge | 48 | 96 | As much as 22.5 | As much as 15 |
| c8i-flex.16xlarge | 64 | 128 | As much as 30 | As much as 20 |
Should you’re at the moment utilizing earlier generations of compute-optimized cases, you possibly can undertake C8i-flex cases with out having to make adjustments to your utility or your workload.
Now obtainable
Amazon EC2 C8i and C8i-flex cases can be found right this moment within the US East (N. Virginia), US East (Ohio), US West (Oregon), and Europe (Spain) AWS Areas. C8i and C8i-flex cases might be bought as On-Demand, Financial savings Plan, and Spot cases. C8i cases are additionally obtainable in Devoted Situations and Devoted Hosts. To study extra, go to the Amazon EC2 Pricing web page.
Give C8i and C8i-flex cases a attempt within the Amazon EC2 console. To study extra, go to the Amazon EC2 C8i cases web page and ship suggestions to AWS re:Submit for EC2 or by means of your traditional AWS Help contacts.
