What is Open Source Software?
Open source software refers to computer programs with source code available for anyone to inspect, modify, and distribute. Unlike proprietary software, open source software is developed collaboratively by a community of developers.
One of the main benefits of open source software is cost savings. Because the source code is freely available, organizations can use and customize the software without paying licensing fees, reducing costs, especially for large-scale deployments.
Another advantage of open source software is strong community support. With a large and active community of developers and users, bugs can be quickly identified and fixed, and new features can be added rapidly.
Well-known open source projects include OpenTelemetry, the Linux operating system, the MySQL database management system, and the Python programming language. These projects have gained widespread adoption and become necessary software stack components.
FAQs About Open Source Software
Gartner®'s "A CTO's Guide to Open-Source Software: Answering the Top 10 FAQs" addresses common questions that organizations have when considering using open-source software.
The article covers various topics, including licensing and legal considerations, security and vulnerability management, integration and customization, community support, contributions, overall ownership cost, and talent acquisition and development.
Licensing and Legal Considerations
Open source software comes with different licensing models, each with its own rules and requirements. Understanding these licenses is important to ensure legal compliance and mitigate potential risks.
Here are some of the most common open source licenses:
MIT License: This license is very permissive. It allows you to use, modify, and distribute the software without many restrictions. However, you have to include the original copyright notice and license text.
Apache License: Similar to the MIT License, but with additional protections for patent rights and legal safeguards. It’s one of the more popular choices for web servers and libraries.
GNU General Public License (GPL): A copyleft license requires any derivative works or modifications also to be released under the same GPL license. This can pose challenges when integrating GPL-licensed code with proprietary software.
When using open source software, it's important to carefully review the license terms and make sure you follow any rules or restrictions. If you don't, your organization could face legal risks, such as breaking copyright laws or violating the license.
Best practices for maintaining legal compliance include:
Create an Open Source Policy: Create guidelines for evaluating, approving, and using open source components within your organization.
Maintain an Inventory: Remember to keep track of all open source components used in your projects, including their licenses and any associated obligations.
Implement Automated Scanning: Set up automated scanning using tools to check your codebase for open source components.
Seek Legal Guidance: If you're not sure about license compatibility or have concerns about potential legal risks, ask legal experts familiar with open source licensing for help.
Contribute Back: When you can, think about sharing any improvements or bug fixes with the open source community.
Remember to handle open source licensing and legal considerations proactively. So you can enjoy the benefits of open source software while reducing potential risks and complying with laws and regulations.
Security and Vulnerability Management
Open source software can be just as secure as proprietary solutions, but it does need active security and vulnerability management. One of the main benefits of open source is that the community can review the code and find potential vulnerabilities. But, this also means that you’re putting your code at risk.
Make sure you have a clear process for reporting vulnerabilities. So, security researchers and community members can report them responsibly. Many open source projects have bug bounty programs or security advisory lists that can help. Keeping your security patches and updates current is equally as important since they often fix vulnerabilities.
When adopting open source software, it's important to check the project's security practices carefully. This includes how they handle security issues, review code, and how often they update for security. It's also a good idea to use automated tools to scan your open source dependencies for known security problems and bug alerts.
It's important to use safe coding practices and regularly check security to reduce risks with open source software. Companies should also have clear rules for using open source and a process for reviewing and approving open source parts before adding them to their systems.
Integration and Customization
Open source software is flexible and can be easily customized and integrated. Many open source projects are designed to be modular and expansible, giving developers the opportunity to add different components to existing systems and workflows. This is particularly useful for organizations with unique requirements or legacy systems that are in need of an update.
One of the key advantages of open source software is the ability to modify the source code to meet specific needs. With access to the codebase, developers can customize the software, add new features, fix bugs, or optimize performance for their particular use case. This level of customization is not typically possible with proprietary software, where the source code is not as easily accessible.
Remember that customizing open source software may require a lot of development work and expertise. Skilled developers who understand the codebase are essential to make the necessary changes and ensure that the customizations are secure and don't cause problems with future updates.
It's also important to consider how the software will integrate with existing systems. Open source software often has ways to connect with other tools and platforms, like APIs or plugins, which can make workflows more efficient.
When you integrate open source components, it's important to follow best practices for software development, like testing, documentation, and version control. Organizations also need a plan for maintaining and updating the integrated components to ensure they stay compatible and secure over time.
Community Support and Contributions
Open source software is made strong by its community. One of the best things about open source is the ability to connect with developers, contributors, and users all around the world who actively support, maintain, and improve the software. Leveraging an open source community has many benefits like:
Expertise Access: Open source communities bring together developers and experienced users with a wide range of skills and knowledge.
Quick Issue Resolution: With a large community of contributors, bugs and issues are often identified and fixed quickly.
Feature Requests and Improvements: Open source communities encourage users to contribute by submitting feature requests, bug reports, and code improvements.
To effectively use the open source community, you need to take part and give back. Here are some guidelines for contributing:
Understand the Community Guidelines: Understand each open source project's guidelines to ensure your contributions align with its goals.
Report Bugs and Issues: If you encounter any bugs or issues, promptly report them to the project's issue tracker. Be sure to give detailed information, including steps to recreate the problem, any error messages, and relevant logs or screenshots.
Contribute Code: If you have the skills and knowledge, consider contributing code fixes, enhancements, or new features. Follow the project's coding standards, write clear documentation, and ensure your code is well-tested before submitting a pull request.
Participate in Discussions: Join the project's forums, mailing lists, or chat channels. Engage in discussions, share your experiences, and provide feedback.
Contribute Documentation: Clear and up-to-date documentation is very important for open source projects. You can help by improving existing documentation, creating tutorials, or translating content.

Total Cost of Ownership (TCO)
One of the most compelling advantages of open source software is its potential for long-term cost savings compared to proprietary alternatives. However, it's important to carefully analyze the Total Cost of Ownership (TCO) to fully understand the true financial implications.
Open source software is often free to get at first. But then there are other costs like deployment, maintenance, support, and training. These hidden costs can add up fast, especially for big business solutions. Also, organizations might need to hire specialized talent or get outside help to make sure everything is done right and keeps running smoothly.
On the other hand, proprietary software usually require more upfront fees and ongoing subscription costs. These expenses can increase with company growth, making it challenging to switch to other solutions because of vendor lock-in.
When evaluating the TCO of open source versus proprietary software, it's important to think about a few things:
Initial acquisition costs (licensing fees, subscription fees, or none for open source)
Implementation and deployment costs (hardware, infrastructure, professional services)
Ongoing maintenance and support costs (internal resources, external support contracts)
Training and talent acquisition costs (upskilling existing staff, hiring specialized professionals)
Scalability and flexibility (ability to adapt to changing business needs without incurring significant additional costs)
Integration costs (compatibility with existing systems and tools)
Exit costs (if deciding to switch solutions in the future)
Remember to weigh all the factors to understand long-term costs carefully. Open source software may require an initial investment but can lead to significant savings over time, especially for organizations with skilled in-house teams dedicated to ongoing maintenance and support.
