On May 10, 2023, Amazon Cloud Technology launched I4g instances powered by AWS Graviton2 processors, whose computing performance is 15% higher than other storage-optimized instances of Amazon Cloud Technology.
With up to 64 vCPUs, 512GiB of memory, and 15TB of NVMe storage, one of the six instance sizes is sure to be a good fit for your storage-intensive workloads: relational and non-relational databases, search engines, file systems, in-memory analytics, batch Processing, streaming, etc. These workloads are often very sensitive to I/O latency and require large amounts of random read/write IOPS as well as high CPU performance.
Specifications are as follows:
I4g instances use AWS Nitro SSD as NVMe storage. Each storage volume can deliver the following performance (all measured using 4KiB blocks):
● Up to 800,000 random write IOPS
● Up to 1 million random read IOPS
● Up to 5600MB/s sequential write
● Up to 8000MB/s sequential reading
4KiB, 8KiB and 16KiB data blocks support tear write protection .
