An HDInsight deployment consists of a head node, a secure gateway node, and one or more data nodes. The head node and data nodes are billed on an hourly basis prorated to the nearest minute that a cluster exists, and the secure node is free. Charges start when the cluster creation completes and stops when you request that the cluster be deleted. There is no concept of de-allocating or putting the cluster “on hold”. Other Azure services associated with HDInsight such as Storage and Data Transfers are billed separately using the standard rates for Storage and Data Transfers. Standard data transfer charges will also apply when transferring data from one region to another.
|Head Node (on an Extra Large (A4) instance): ||$-.-- - $-.-- per hour |
|Each Data Node (on a Large (A3) instance): ||$-.-- - $-.-- per hour |
* Actual price is determined by your committed spend level, commitment duration and whether you choose to pay monthly or pre-pay.
|Secure Gateway Node (on a Medium (A2) instance): ||Free |
Example of a 10 node cluster that will exist for 24 hours:
- The Secure Gateway Node is free.
- For a pay-as-you-go plan the head node is $0.64 USD per hour or $15.36 USD per 24-hour day.
- 1 data node is $0.32 USD per hour or $7.68 USD per 24-hour day. 10 data nodes would be 10 times that amount, or $76.80 USD per 24-hour day.
- The total compute cost for a 10 data node cluster under the pay-as-you-go plan for a cluster that exists for 24 hours is $92.16 USD.
- Storage and data transfer costs are billed separately.
If you need more nodes than are available by default for your subscription, see the “What if I need more data nodes?” section below.
