After the launch of the Amazon Elastic Compute Cloud (AMAZON EC2) memory-optimized instances R8i and R8i-Flex and the general M8i and M8i-Flex accounting instances, I am glad that I can announce the general availability of the calculation C8I and the C8I-Flex preparation. Memory on PCPU. These instances provide the highest performance and the fastest bandwidth between the comparable Intel processors in the cloud.
The C8I and C8I-Flex instances offer up to 15 percent better price performance and 2.5 times the width of the memory band compared to the C7i and C7I-Flex instances. The C8I and C8I-FLEX instances are up to 60 percent faster for Nginx web applications, up to 40 percent faster for AI Deep Learning recommendations and 35 percent faster for MEMCACHED stores compared to C7I and C7I-Flex cases.
The C8I and C8I-Flex instances are ideal for starting workload, such as web servers, cache, apache, elasticsearch, batch, distributed analysts, high-performance computer techniques (HPC), advertising serving, multiplayer games and video encoding.
Like other instances 8. Generations use these instances of new AWS cards sixth generation AWS Nitro and supply up to twice as many network and Amazon Elastic Block Storage (Amazon EBS) bandwidth compared to previous generation instances. They also support the bandwidth configuration with 25 % adjustments between network and Amazon EBS bandwidth, allowing better database performance, processing and logging speed.
C8I examples
The C8I instances provide up to 384 VCPu and 768 TB of memory, including bare metal instances that provide reserved access to the underlying physical hardware. These instances help you launch a computing workload such as CPU -based inference and video streaming that requires the largest instance size or high processor continuously.
Here are specifications for instance C8I:
| The size of an instance | Pcpus | Memory (GIB) | The bandwidth of the band (GBPS) | EBS bandwidth (GBPS) |
| C8i.lage | 2 | 4 | Up to 12.5 | Up to 10 |
| C8i.xlarge | 4 | 8 | Up to 12.5 | Up to 10 |
| C8I.2XLAGE | 8 | 16 | Up to 15 | Up to 10 |

| C8i.Metal-96xl | 384 | 768 | 100 | 80 |
Instance C8i-Flex
The C8I-Flex instance is a lower costly C8I instance, with 5 percent better price performance for 5 percent lower prices. These instances are designed for workload, which benefits from the latest generation performance, but do not use all computing resources. These cases can reach full power of the CPU 95 percent of the time.
Here are specifications for instance C8I-FLEX:
| The size of an instance | Pcpus | Memory (GIB) | The bandwidth of the band (GBPS) | EBS bandwidth (GBPS) |
| C8i-flex.lage | 2 | 4 | Up to 12.5 | Up to 10 |
| C8I-FLEX.XLAGE | 4 | 8 | Up to 12.5 | Up to 10 |
| C8I-FLEX.2XLAGE | 8 | 16 | Up to 15 | Up to 10 |
| C8I-FLEX.4XLAGE | 16 | 32 | Up to 15 | Up to 10 |
| C8I-FLEX.8XLAGE | 32 | 64 | Up to 15 | Up to 10 |
| C8I-FLEX.12XLAGE | 48 | 96 | Up to 22.5 | Up to 15 |
| C8I-FLEX.16XLAGE | 64 | 128 | Up to 30 | Up to 20 |
If you are currently using earlier generations of computing instances of optimized, you can accept C8I-Flex instances without having to make changes in your application or workload.
Now available
The Amazon EC2 C8I and C8I-Flex are available today in the US East (N. Virginia), US East (Ohio), US West (Oregon) and Europe (Spain) AWS AWS. Instance C8I and C8I-Flex can be purchased as on request, savings plan and Spot instance. C8I instances are also available in reserved cases and reserved hosts.
