Getting an Edge on Point of Service


Save money and lock down your POS environment with SUSE Manager for Retail

A Point of Service (POS) network is a highly specialized environment that requires specialized tools. Traditional solutions depend on proprietary hardware running proprietary software that limits flexibility and enforces vendor lock-in. An alternative approach is to build the retail environment around general-purpose, PC-based client systems and general-purpose management tools. Implementing a retail environment through general-purpose systems solves the lock-in problem, but it fails to provide the security, efficiency, and convenience of a system specifically designed for the needs of the retail industry. If you’re looking for a solution that is specifically designed for retail, but avoids the complications and added expense of proprietary tools, try SUSE Manager for Retail. SUSE Manager for Retail is an open source infrastructure management solution that is powerful, flexible, secure, and easy to customize.

What is SUSE Manager for Retail?

SUSE Manager for Retail is an open source infrastructure management solution that is carefully crafted for the retail industry. You can use SUSE Manager for Retail to keep watch over point-of-service terminals, reverse-vending systems, kiosks, self-service systems, and even non-retail devices at schools, banks or hospitals. SUSE Manager for Retail can also manage Linux workstations, servers, and other assets, thus consolidating POS and conventional infrastructure in a unified management framework.

Your SUSE Manager for Retail system offers a comprehensive interface that lets you:

  • Create, deploy, and maintain images for POS devices that are optimized for retail applications, including support for secure payments protocols.
  • Automatically update or patch all retail terminals from one central location.
  • Automatically monitor, track, and report any deviation from compliance of every Linux-based system in your environments.
  • Lower costs by extending the lifetime of legacy hardware.
  • Optimize operations through scripting and programming for continuous integration.

If you administer a POS retail environment, SUSE Manager for Retail will help you reduce costs, streamline operations, increase flexibility, enhance reliability, and improve uptime.

The Retail Environment

At the local level, SUSE Manager for Retail lets you deploy, configure, manage, and audit a collection of POS systems (Figure 1). Ask SUSE about the SLEPOS client, which is designed for easy and complete integration with SUSE Manager for Retail.

A multi-site enterprise environment benefits still more from the powers of SUSE Manager for Retail (Figure 2). The SUSE Manager for Retail server unifies dissimilar local environments within a single unified management interface. Branch servers operating at the local level provide proxy, DNS, and other services to improve performance and minimize network traffic.

Why SUSE Manager for Retail?

SUSE Manager for Retail oversees the complete lifecycle of your Linux-based point of service systems.  You can install system images for your POS systems from pre-configured image templates or even create your own custom images. SUSE Manager for Retail also provides remote deployment and provisioning for point of service systems. The Salt automated configuration environment included with SUSE Manager for Retail lets you pre-define complete systems in a declarative format that is easy to adapt for fast and efficient rollout. SUSE Manager for Retail locks down software installation, forcing client systems to receive updates through managed channels that enhance security and enforce standardization to minimize reconfiguration and lost work time.

Efficiency and Cost Savings

SUSE Manager for Retail reduces risk and minimizes hardware and admin expenses. The minimal hardware requirements of the SLEPOS operating system lets you build your retail infrastructure around commodity hardware  and even  extend the life of older POS terminals that may not be compatible with other systems. The Salt configuration management system at the heart of SUSE Manager enables IT staff to automate  rollouts and reconfiguration, and SUSE Manager for Retail offers additional staff time savings through auditing, software updates, and automation. An administrator without advanced scripting skills can use the web forms built into SUSE Manager for Retail to describe and implement complex configurations for any store environment.

Easier Compliance

Manager for Retail makes it easy to verify that your retail assets are in compliance with internal corporate policies and external regulations. You can view the compliance status of any POS system anywhere in the network (Figure 5). Your staff can use SUSE Manager for Retail to create an inventory of all managed systems. Once that inventory is available, SUSE Manager for Retail continuously monitors all clients and reports on any deviation from the current patch level or any other compliance requirement.

SUSE Manager for Retail can also monitor your systems automatically to ensure compliance with external standards such as CVE (Common Vulnerabilities and Exposures) and  OpenSCAP (Security Content Automation Protocol).

Automation Edge

You can use the SUSE Manager XML-RPC API to integrate SUSE Manager for Retail with custom applications written in Python, Perl, and other programming languages. An optional text-based command interface makes it easy to build SUSE Manager commands into Bash scripts and other admin utilities. This strong support for automation, combined with the powerful configuration and deployment features described earlier in this paper, make SUSE Manager for Retail a natural fit for Continuous Integration/Continuous Delivery scenarios.


The initial release of version 3.2 of SUSE Manager for Retail 3.2 was targeted at new installations and not enabled for migration of legacy installations of the retail server or SLEPOS client. Version 3.2 now supports migration as a technical preview. For more information, see the SUSE Manager for Retail Migration Guide.

SUSE Manager for Retail lets you manage the full lifecycle of your POS retail infrastructure from a single interface. You can lock down control of your retail systems through software channels, automated configuration, auditing, and other powerful features.  Easy administration and strong support for automation improve efficiency and lower total cost of ownership.
