d3.2xlarge is AWS's storage-optimized EC2 size at 8 vCPU and 64 GiB. In the name, "d" is dense local storage, "3" is the generation and "2xlarge" is the size within the d3 family. It runs on Intel Xeon Platinum 8259 (Cascade Lake) at 3.1 GHz, and AWS introduced it in December 2020. d3 is the current generation of the d family, so there is no newer AWS size to migrate to. On Rackspace Spot the same shape is mh.vs1.xlarge — 8 vCPU, 64 GiB, matched on both dimensions, $0.999/hr on AWS in US East (N. Virginia), from $0.031/hr on Rackspace Spot.
Match qualityNo local disk
d3.2xlarge comes with 6 × 1,980 GB NVMe SSD attached to the machine. Rackspace Spot nodes use network storage only, so that disk does not come with it.
If you were using the local disk as fast scratch space — temporary files, a local cache, an index — you will need a persistent volume or object storage instead, and both are slower to read. If it was just extra space you never depended on, nothing changes.
