Questions
- How many DBUs does i4i.4xlarge use on Databricks?
- i4i.4xlarge uses 5.5 DBUs an hour on Databricks classic compute without Photon. With Photon it uses 15.95 DBUs an hour on Jobs Compute and 11 on All-Purpose Compute, as Databricks' price list gives them.
- How much does i4i.4xlarge cost an hour on Databricks?
- In US East (N. Virginia), 1 i4i.4xlarge node on Jobs Compute costs $2.20 an hour: $0.825 to Databricks for 5.5 DBUs at $0.15 each, and $1.37 to AWS for the machine. On All-Purpose Compute the same node costs $4.40 an hour, and on Lakeflow pipelines Core $2.47. A cluster pays this for every worker and for the driver.
- Does Photon cost more on i4i.4xlarge?
- Yes, by the hour: with Photon, 1 i4i.4xlarge node on Jobs Compute in US East (N. Virginia) costs $3.77 an hour instead of $2.20, because it uses 15.95 DBUs an hour instead of 5.5. It saves money only when the job finishes fast enough to make up the difference.
- Which region is cheapest for i4i.4xlarge on Databricks?
- US East (N. Virginia), at $2.20 an hour for 1 node on Jobs Compute, against $3.02 in South America (São Paulo), the dearest of the 16 regions listed here that offer it. Databricks charges the same for a DBU of Jobs Compute in every AWS region listed, so the gap is the machine.
- What is the same size as i4i.4xlarge on the other clouds?
- The nearest worker types of the same kind are Standard_L16s_v3 on Azure and n2-standard-16 on Google Cloud. Each cloud gives its own DBUs an hour for its types, so compare what a cluster costs in the calculator, not the DBUs alone.
- What is the next size up or down from i4i.4xlarge?
- One size down is i4i.2xlarge, at 2.75 DBUs an hour; one size up is i4i.8xlarge, at 11. Within a family, DBUs and the machine price grow with the vCPUs, so 2 nodes of a size cost about what 1 node of twice the size costs.
