IP address and cloud resource requirements for Virtual Warehouses running on AWS environments
Learn about the estimated number of IP addresses and cloud resources required to run Virtual Warehouses on AWS environments for Cloudera Data Warehouse (CDW) Public Cloud.
Virtual Warehouse requirements:
Each compute node in a Virtual Warehouse that runs on AWS environments requires 8 IP addresses. Each executor needs one compute node, so the size of your Virtual Warehouse contributes to the number of IP addresses required. To calculate the number of IP addresses required for custom sizes, multiply the number of executors by 8 and add for the shared services as specified in the following sections.
Shared services requirements for Database Catalogs:
Virtual Warehouses also require shared services for the Database Catalog.
Additional shared services requirements:
The usage for other shared services is different for Hive Virtual Warehouses and Impala Virtual Warehouses. Here are the different requirements for Hive versus Impala Virtual Warehouses:
- Hive Virtual Warehouses add 1 compute node for each executor and 1 shared services node for the HiveServer for each Virtual Warehouse.
- Impala Virtual Warehouses add 1 compute node for each executor, 1 or 2 compute nodes for the coordinator, depending on the HA configuration, and 1 shared services node per Virtual Warehouse for Impala catalogd.
The following tables summarize the approximate number of IP addresses and cloud resources you should plan for Virtual Warehouses on AWS environments.
| Size (# executors) | # Compute nodes for executors | # Shared services nodes Database Catalog | # Shared services nodes for HiveServer | Total IP addresses required |
|---|---|---|---|---|
| XSMALL (2) | 2 | 3 | 1 |
Executor nodes: 2 nodes X 8 = 16 Shared services nodes: 3 + 1 = 4 nodes X 25 = 100 TOTAL = ~116 IP addresses |
| SMALL (10) | 10 | 3 | 1 |
Executor nodes: 10 nodes X 8 = 80 Shared services nodes: 3 + 1 = 4 nodes X 25 = 100 TOTAL = 180 IP addresses |
| MED (20) | 20 | 3 | 1 |
Executor nodes: 20 nodes X 8 = 160 Shared services nodes: 3 + 1 = 4 nodes X 25 = 100 TOTAL = 260 IP addresses |
