Posit Team: Each product on a separate server

In this configuration, each product is installed on a separate Linux server.

Posit Team: Load-balanced and high availability cluster

In this configuration, each product is installed on two or more separate Linux servers and requires:

  • User’s home directories to be stored on an external shared file server (Workbench)
  • Application data to be stored on an external shared file server (Connect and Package Manager)
  • Application metadata to be stored on an external PostgreSQL database server (All)

Posit Team: Running inside a Kubernetes cluster

In this configuration, each product is installed within the kubernetes cluster and requires:

  • User’s home directories to be stored on an external shared file server (Workbench)
  • Application data to be stored on an external shared file server (Connect and Package Manager)
  • Application metadata to be stored on an external PostgreSQL database server (All)

Posit provides Helm Charts to help maintain this entire installation.
