The AAA Dilemma: Managed vs. Open-Source Solutions


5th of April 2024

Introduction to Managed AAA vs. Open-source AAA

Authentication, Authorization, and Accounting (AAA) servers are critical for controlling access, enforcing policies, and generating reports in telecommunication networks. As Communications Services Providers (CSPs), Internet Service Providers (ISPs), and Broadband Providers look to upgrade their AAA platforms, a key question arises – should they opt for a managed software vendor solution or an open-source option like FreeRADIUS? We analyze the pros, cons, costs, and key considerations for both approaches.

Managed AAA: Strategic Value with Expert Support

A software vendor AAA solution comes with several advantages that can provide long-term strategic value:

  • Access to reliable expert support for quick issue resolution and maximum uptime.
  • Advanced built-in features that reduce time-to-market for rolling out new services.
  • Customizable to your specific network needs with vendor assistance.
  • Regular security updates and threat management.
  • Seamless integration capabilities backed by vendor expertise.
  • Scalability to handle increasing loads without compromising performance.
  • Streamlined operations with user-friendly interfaces.

The higher initial investment pays off over time through greater operational efficiency, reduced downtime, quick rollouts of new features, and alignment with long-term business goals.

Open Source AAA: Flexible and Cost-Effective

Using a free open-source AAA platform like FreeRADIUS has some potential benefits:

  • Lower upfront software licensing costs.
  • Highly customizable to your needs.
  • Scalable capabilities, though may require tuning.
  • Avoid vendor lock-in.

However, open-source solutions lack expert support and rely on community resources.

The long-term total cost of ownership (TCO) may be higher due to the need for:

  • In-house technical resources for feature development, customization, security, integration.
  • Ongoing training and management of complex operations.
  • More effort to align AAA with strategic goals.

Making the Optimal Choice

When selecting between managed and open-source AAA, organizations should consider factors like:

  • Need for responsive expert support vs. available in-house resources.
  • Time-to-market and advanced feature requirements.
  • Integration needs and IT environment complexity.
  • Scalability and performance demands.
  • Operational overhead of managing solutions in-house.
  • Strategic business objectives and long-term roadmap.

Striking the right balance between the benefits of an enterprise-grade AAA platform and the lower initial costs of open-source can lead telecoms to the ideal AAA solution for their specific technical and business needs.
