In the ever-evolving world of information technology, open source software has become a foundational pillar. From the Linux operating system to tools like WordPress, Docker, and Proxmox, open source is no longer just an alternative — it’s a driving force behind innovation, scalability, and cost-effective infrastructure.
This article explores what open source is, why it matters, and how businesses — including those supported by FYDUS IT Solutions — benefit from incorporating it into their technology stack.
What Is Open Source?
Open source software is software with source code that anyone can view, modify, and distribute. Unlike proprietary software (which restricts access to its codebase and functionality), open source projects invite developers and users to improve, adapt, and share the software freely under a defined licence.
Popular open source licences include:
- MIT Licence
- GNU General Public Licence (GPL)
- Apache Licence 2.0
These licences ensure that the software remains free to use and evolve over time, with contributions from a global community of developers.
Key Characteristics of Open Source
Open source software is typically:
- Free to use – No upfront licensing costs
- Transparent – Source code is publicly available
- Customisable – Tailor it to your specific needs
- Community-driven – Improvements are made collaboratively
- Secure – With large communities reviewing code for bugs and vulnerabilities
Examples of Open Source Software in Business
Open source powers much of the internet and is widely used in business infrastructure. Common examples include:
- Operating Systems: Ubuntu, Debian, CentOS, Rocky Linux
- Virtualisation: Proxmox VE, Xen, KVM
- Web Servers: Apache, Nginx, Caddy
- Database Systems: MySQL, PostgreSQL, MariaDB
- Development Tools: Git, Node.js, PHP, Python
- CMS Platforms: WordPress, Joomla, Drupal
- Containers and Orchestration: Docker, Kubernetes
FYDUS IT Solutions regularly works with many of these tools to build and support client infrastructure.
The Business Case for Open Source
Many businesses — from startups to enterprises — are turning to open source not only to reduce software costs but also to gain greater control over their technology.
Benefits of Open Source for Businesses
- Lower Total Cost of Ownership
Avoid high licensing fees and renewals, especially for server software and cloud platforms. - Flexibility and Customisation
You’re not locked into a vendor’s way of doing things — you can shape the software to meet your business needs. - Strong Security and Transparency
With open code, security issues are identified and patched quickly. Community eyes are often better than closed doors. - Vendor Independence
Open source gives you the freedom to switch providers, migrate systems, or self-host without being locked into a contract. - Innovation and Agility
Many open source tools lead the way in emerging tech — such as containers, machine learning, and edge computing.
Addressing Common Concerns
Despite its benefits, some businesses hesitate to adopt open source due to concerns around support or complexity.
