Questions
- How many DBUs does i4i.2xlarge use on Databricks?
- i4i.2xlarge uses 2.75 DBUs an hour on Databricks classic compute without Photon. With Photon it uses 7.98 DBUs an hour on Jobs Compute and 5.5 on All-Purpose Compute, as Databricks' price list gives them.
- How much does i4i.2xlarge cost an hour on Databricks?
- In US East (N. Virginia), 1 i4i.2xlarge node on Jobs Compute costs $1.10 an hour: $0.412 to Databricks for 2.75 DBUs at $0.15 each, and $0.686 to AWS for the machine. On All-Purpose Compute the same node costs $2.20 an hour, and on Lakeflow pipelines Core $1.24. A cluster pays this for every worker and for the driver.
- Does Photon cost more on i4i.2xlarge?
- Yes, by the hour: with Photon, 1 i4i.2xlarge node on Jobs Compute in US East (N. Virginia) costs $1.88 an hour instead of $1.10, because it uses 7.98 DBUs an hour instead of 2.75. It saves money only when the job finishes fast enough to make up the difference.
- Which region is cheapest for i4i.2xlarge on Databricks?
- US East (N. Virginia), at $1.10 an hour for 1 node on Jobs Compute, against $1.51 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.2xlarge on the other clouds?
- The nearest worker types of the same kind are Standard_L8s_v3 on Azure and n2-standard-8 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.2xlarge?
- One size down is i4i.xlarge, at 1.38 DBUs an hour; one size up is i4i.4xlarge, at 5.5. 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.
