IP address and cloud resource requirements for Virtual Warehouses running on Azure environments
Learn about the estimated number of IP addresses and cloud resources required to run Virtual Warehouses on Azure environments for Cloudera Data Warehouse (CDW) Public Cloud.
Virtual Warehouse requirements:
Each compute node in a Virtual Warehouse that runs on Azure environments requires 11 IP addresses (for pods and for the node itself). 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 11 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 Database Catalogs. When an environment is activated with only the default Database Catalog, it consumes 3 shared services nodes. In general, an environment with one default Database Catalog and one additional Database Catalog consumes 4 shared services nodes. Each shared services node requires 31 IP addresses (for pods and the node itself).
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 Azure environments.
