Deploying PCI Linx

The recommended deployment method for PCI Linx is on a Windows 11 computer connected to Microsoft Azure / Entra. The database can be deployed on-premises, Microsoft Azure or Amazon AWS.

The PCI Linx application deploys efficiently on correctly configured Virtual Machines (VMs). This method of installation is commonly used by many of our clients with support from their IT Department. We unfortunately cannot support installation on Virtual Machines.
