Polarity Server v5 - Administrator's Overview

Server Requirements

We recommend the following server specs for a deployment of up to approximately 50 users:

• 4 Cores

• 32 GB of RAM

• 250 GB storage

  • ensure whichever volume contains /var has enough storage for containers

Deployment Methods

1. Amazon Machine Image (AMI)

   1. Amazon Linux 2023

2. Single server container deployment

   1. Supported Operating Systems:

      1. Debian-Based Distros, such as:

         1. Debian 11 / 12
