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 joyful to announce the overall availability of compute-optimized C8i and C8i-flex cases powered by customized Intel Xeon 6 processors accessible 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 best efficiency and quickest reminiscence bandwidth amongst comparable Intel processors within the cloud.
The C8i and C8i-flex cases provide 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 net functions, 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 operating compute-intensive workloads, akin to net 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 era cases, these cases use the brand new 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 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 assist you to to run compute-intensive workloads, akin to CPU-based inference, and video streaming that want the most important occasion sizes or excessive CPU repeatedly.
Listed here are the specs for C8i cases:
| Occasion measurement | 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 most recent era efficiency however don’t totally make the most of all compute sources. These cases can attain as much as the complete CPU efficiency 95 % of the time.
Listed here are the specs for the C8i-flex cases:
| Occasion measurement | 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 |
In the event you’re presently utilizing earlier generations of compute-optimized cases, you’ll be able to undertake C8i-flex cases with out having to make adjustments to your utility or your workload.
Now accessible
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 will be bought as On-Demand, Financial savings Plan, and Spot cases. C8i cases are additionally accessible in Devoted Situations and Devoted Hosts. To be taught extra, go to the Amazon EC2 Pricing web page.
Give C8i and C8i-flex cases a attempt within the Amazon EC2 console. To be taught extra, go to the Amazon EC2 C8i cases web page and ship suggestions to AWS re:Publish for EC2 or by way of your regular AWS Assist contacts.
