Open source in production.

A technical choice, not an ideology.

Open source has played an important role throughout my professional experience. Open operating systems, databases, automation tools, network components, VoIP platforms and infrastructure services have proven capable of supporting complex environments and production workloads.

This does not mean that open-source software is automatically superior to proprietary software. Source availability is an important property, but it does not replace project quality, technical maturity, maintenance, documentation or the ability to operate the system correctly.

The decision must begin with the problem to solve, the operational requirements and the level of responsibility the organisation is able to assume.

Why I consider open source.

Open technology can provide practical advantages when it makes the system easier to understand and allows technical control to be retained over time.

The ability to inspect how components work, use documented protocols and integrate different tools reduces unnecessary dependencies and supports interoperable architecture.

• technical transparency and verifiability;
• use of open protocols, formats and interfaces;
• ability to integrate and automate the system;
• greater portability of data and configuration;
• reduced dependence on a single supplier;
• availability of communities, expertise and shared documentation;
• ability to retain infrastructure knowledge within the organisation.

What I assess before adoption.

I would not place a technology in production merely because it is open source or widely known. I assess the project using the same criteria I would apply to any critical component.

• maturity and stability of releases;
• frequency, quality and predictability of updates;
• vulnerability handling and incident response times;
• community activity and sustainability of governance;
• quality of technical documentation;
• availability of internal skills or expertise in the market;
• compatibility with existing standards, systems and processes;
• backup, recovery, migration and update procedures;
• availability of professional support where needed;
• risk of dependence on a small number of maintainers or one organisation.

A public repository and a high download count are not, by themselves, guarantees of continuity. Project health, governance and the ability to respond when problems arise are part of the architectural assessment.

Open source does not mean zero cost.

The absence of a licence fee does not remove the total cost of the solution. Costs may move into analysis and design, installation, integration, automation, training, monitoring, patching, compatibility testing, operational documentation, specialist support and incident response.

A well-engineered open-source solution can be efficient, sustainable and independent. The same solution, adopted without expertise or maintenance, may become fragile and more expensive than a properly operated proprietary product.

Open code is not enough.

The ability to inspect code can support transparency, review and defect discovery. It does not, however, make a product automatically secure.

Security also depends on development quality, vulnerability remediation, dependency management, configuration, reduction of exposed surface, access control, monitoring, verified backups and incident-response procedures.

An outdated or poorly configured open-source component remains vulnerable like any other software. The advantage of openness becomes practical only when operations are capable of using it.

When it is not necessarily the best choice.

There are contexts in which a proprietary solution may be more appropriate.

• certifications or integrations are available only for a specific product;
• the open-source project lacks sufficiently reliable governance;
• internal expertise and qualified support are unavailable;
• implementation times are incompatible with operational needs;
• the proprietary product provides decisive capabilities, support or guarantees;
• the risk of customisation exceeds the expected benefit;
• the organisation cannot sustain maintenance and updates directly.

The objective is not to avoid proprietary software at any cost. It is to avoid dependencies that are not understood and to choose the most appropriate operating model for the service.

From technology to production.

Bringing open-source technology into production means turning a software component into a governed service.

1. clearly defined requirements and responsibilities;
2. documented architecture;
3. repeatable, version-controlled configuration;
4. installation and update procedures;
5. technical and functional monitoring;
6. verified backup and recovery;
7. vulnerability management;
8. capacity and continuity criteria;
9. a migration or replacement plan;
10. shared knowledge rather than dependence on one individual.

The value lies not only in the selected software, but in the ability to keep it observable, updatable, recoverable and understandable over time.

Open when it creates real control.

I prefer open technologies when they enable systems that are understandable, interoperable and manageable while preserving control over data and architectural choices.

I do not treat open source as an end in itself. It is a tool that must demonstrate reliability in the real context where it will be used.

• Is it suitable for the service?
• Can we operate it securely?
• Can we update, observe and recover it?
• Is its governance sustainable?
• Does it genuinely reduce risk and dependency over the medium term?

When the answers are solid, open source can provide an excellent foundation for reliable and durable infrastructure.
