Proprietary vs Open Source Software Models

Proprietary Model (Closed Source Development & Licensing)

1. Utilization of Open Source Software Modules

   • Proprietary software development often begins by leveraging open-source libraries, frameworks, and tools to reduce costs and accelerate development.
   • These modules provide foundational functionality but do not dictate the openness of the final product.

2. Closed Application Development

   • The development team builds proprietary features, integrations, and user experiences around the core modules.
   • Access to the source code is restricted to internal teams, ensuring that intellectual property (IP) remains controlled.
   • Security, performance, and unique value propositions are developed in-house without external contributions.

3. Software Licensing and Monetization

   • The final product is sold through perpetual licenses, subscription models, or SaaS offerings.
   • Customers pay for the right to use the software but do not have access to modify the source code.
   • Additional revenue is generated through maintenance contracts, updates, premium features, and enterprise editions.
   • Vendors maintain tight control over development, updates, and feature rollouts.

4. Business Strategy & Scaling

   • Companies aim to create vendor lock-in, ensuring customers rely on their ecosystem.
   • Profitability depends on selling software at scale while minimizing unauthorized distribution.
   • Support is often included in licensing fees, but premium support and professional services can be sold separately.

Open Source Model (Collaborative Development & Support-Based Monetization)

1. Utilization of Open Source Software Modules

   • The foundation of the product is built on publicly available open-source components.
   • The company may contribute to these modules to enhance functionality, performance, and security.

2. Open Application Development with Community Collaboration

   • Unlike proprietary software, development is conducted in the open, with external contributors, partners, and users participating.
   • Companies may lead the development but encourage community contributions, allowing for faster iteration and innovation.
   • Transparency fosters trust, and the community can help identify bugs, suggest improvements, and even contribute new features.

3. Software Packaging & Commercial Support Monetization

   • Instead of selling software licenses, revenue is generated through:
     • Enterprise support contracts (e.g., Red Hat’s model)
     • Managed services and cloud hosting (e.g., OpenShift, AWS supporting open-source tools)
     • Custom development and consulting services
     • Premium features or enterprise add-ons (dual licensing models)
   • The software itself is freely available, but businesses pay for additional services and guarantees.

4. Business Strategy & Scaling

   • The goal is to create a large, engaged user base that benefits from the open ecosystem while monetizing enterprise needs.
   • Companies differentiate by offering stability, security hardening, and enterprise-grade features.
   • Community contributions can reduce R\&D costs and accelerate innovation.
   • Unlike proprietary models, open-source businesses often focus on long-term relationships and service excellence rather than license enforcement.

Key Differences & Trade-offs

Hybrid Approaches

Many companies blend these models to balance openness and profitability:

• Dual Licensing (e.g., MongoDB, ElasticSearch, Redis Enterprise)
  • Open-source community edition, but proprietary enterprise edition with extra features.
• Open Core Model (e.g., GitLab, HashiCorp)
  • Core features are open source, but enterprise enhancements require a paid license.
• Cloud-First Open Source (e.g., AWS RDS for MySQL/PostgreSQL, Red Hat OpenShift)
  • Software is open, but monetization happens through hosted services and enterprise support.
