The default method to install Veriscope is to use Veriscope Infrastructure as Code (IaC) which uses AWS, Terraform, and Ansible. This is the recommended approach. And gives you the benefit of not having to manage the creation of SSH keys, EC2 instances, users, etc. before you can install Veriscope.
Alternatively, you can use our legacy bash Veriscope Install Script, however, note that this is more involved and will require you to set-up and manage infrastructure yourself.
