External persistent critical services (PCS)¶

概要¶

The DataRobot application supports the integration of external components for Persistent Critical Services (PCS), enabling the use of either cloud-managed services or in-house provisions.

DataRobot recommends opting for cloud-managed services (external PCS) instead of the Internal PCS.

The PCS includes four primary services: PostgreSQL, Redis, MongoDB, and RabbitMQ.

DataRobot recommends using compatible versions of these services as specified for your DataRobot release.

DataRobot Release(s)	Mongo	PostgreSQL	Redis	RabbitMQ
`9.x`	`6.x`	`12.x`, `13.x`	`6.x`, `7.x`	`3.13.x`
`10.x`	`6.x`	`12.x`, `13.x`	`6.x`, `7.x`	`3.13.x`
`11.0`	`7.0`	`14.x`	`7.x`	`4.0` (non-HA)
`11.1`	`7.0`	`14.x`	`7.x`	`4.0` (non-HA)

Hardware requirements¶

PostgreSQL Database

vCPU	メモリー	Disk Size
4	8 GB	250 GB

Mongo Database

vCPU	メモリー	Disk Size
2	4 GB	250 GB

Redis Cache

vCPU	メモリー	Disk Size
1	2 GB	10 GB

備考

You should match these hardware requirements to the appropriate instance sizes offered by your chosen managed service cloud provider. Adjust these selections based on your specific needs.

External PCS provisioning¶

DataRobot recommends using the provided Terraform modules to provision the required resources for your cloud environment.

For AWS, use the dedicated Terraform module for AWS, which defines instance provisioning, security groups, and required resources.
For Azure, use the dedicated Terraform module for Azure, which provisions database instances, private links, and security groups.
For Google Cloud, use the dedicated Terraform module for GCP, which provisions database instances, private links, and security groups.

DataRobot PCS Helm chart¶

During the installation, ensure you configure the appropriate flags to enable or disable the internal deployment of each service. For a complete example, refer to the override/minimal_datarobot-pcs-external_values.yaml file.

services:
  mongodb:
    # -- Mongo service on/off
    enabled: false
  postgresql:
    # -- PostgreSQL service on/off
    enabled: false
  redis:
    # -- Redis service on/off
    enabled: false
  rabbitmq:
    # -- RabbitMQ service on/off
    enabled: true

備考

It is possible to externalize one or more services while using the internal versions of others.
