After launching Amazon Elastic Compute Cloud (Amazon EC2) memory-optimized R8i and R8i-flex situations and general-purpose M8i and M8i-flex situations, I’m pleased to announce the final availability of compute-optimized C8i and C8i-flex situations 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 situations ship the best efficiency and quickest reminiscence bandwidth amongst comparable Intel processors within the cloud.
The C8i and C8i-flex situations supply as much as 15 % higher price-performance, and a pair of.5 instances extra reminiscence bandwidth in comparison with C7i and C7i-flex situations. The C8i and C8i-flex situations are as much as 60 % sooner for NGINX net functions, as much as 40 % sooner for AI deep studying suggestion fashions, and 35 % sooner for Memcached shops in comparison with C7i and C7i-flex situations.
C8i and C8i-flex situations are perfect for working compute-intensive workloads, comparable 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 technology situations, these situations 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 situations. In addition they assist bandwidth configuration with 25 % allocation changes between community and Amazon EBS bandwidth, enabling higher database efficiency, question processing, and logging speeds.
C8i situations
C8i situations present as much as 384 vCPUs and 768 TB reminiscence together with naked steel situations that present devoted entry to the underlying bodily {hardware}. These situations provide help to to run compute-intensive workloads, comparable to CPU-based inference, and video streaming that want the most important occasion sizes or excessive CPU constantly.
Listed below are the specs for C8i situations:
| Occasion dimension | vCPUs | Reminiscence (GiB) | Community bandwidth (Gbps) | EBS bandwidth (Gbps) |
| c8i.giant | 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 situations
C8i-flex situations are a lower-cost variant of the C8i situations, with 5 % higher worth efficiency at 5 % decrease costs. These situations are designed for workloads that profit from the newest technology efficiency however don’t totally make the most of all compute sources. These situations can attain as much as the complete CPU efficiency 95 % of the time.
Listed below are the specs for the C8i-flex situations:
| Occasion dimension | vCPUs | Reminiscence (GiB) | Community bandwidth (Gbps) | EBS bandwidth (Gbps) |
| c8i-flex.giant | 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 |
When you’re at present utilizing earlier generations of compute-optimized situations, you’ll be able to undertake C8i-flex situations with out having to make adjustments to your software or your workload.
Now accessible
Amazon EC2 C8i and C8i-flex situations can be found immediately within the US East (N. Virginia), US East (Ohio), US West (Oregon), and Europe (Spain) AWS Areas. C8i and C8i-flex situations will be bought as On-Demand, Financial savings Plan, and Spot situations. C8i situations are additionally accessible in Devoted Situations and Devoted Hosts. To study extra, go to the Amazon EC2 Pricing web page.
Give C8i and C8i-flex situations a attempt within the Amazon EC2 console. To study extra, go to the Amazon EC2 C8i situations web page and ship suggestions to AWS re:Submit for EC2 or by means of your normal AWS Assist contacts.
