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 out there 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 p.c higher price-performance, and a pair 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 p.c quicker for NGINX internet functions, as much as 40 p.c quicker for AI deep studying advice fashions, and 35 p.c 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. Additionally they help bandwidth configuration with 25 p.c 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 aid you to run compute-intensive workloads, comparable to CPU-based inference, and video streaming that want the most important occasion sizes or excessive CPU repeatedly.
Listed below are the specs for C8i cases:
| Occasion measurement | 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 cases
C8i-flex cases are a lower-cost variant of the C8i cases, with 5 p.c higher worth efficiency at 5 p.c decrease costs. These cases are designed for workloads that profit from the most recent technology efficiency however don’t absolutely make the most of all compute assets. These cases can attain as much as the total CPU efficiency 95 p.c of the time.
Listed below are the specs for the C8i-flex cases:
| Occasion measurement | 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 |
In case you’re at present utilizing earlier generations of compute-optimized cases, you may undertake C8i-flex cases with out having to make modifications to your utility or your workload.
Now out there
Amazon EC2 C8i and C8i-flex cases 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 cases may be bought as On-Demand, Financial savings Plan, and Spot cases. C8i cases are additionally out there in Devoted Cases 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:Submit for EC2 or by way of your regular AWS Assist contacts.
