The term open source refers to something that people can modify and share because it is designed to be publicly accessible. So what exactly is an open source software and how is open source used in software development. Let’s find out by reading the article below.
What is an open source software?
Open Source Software (OSS) is software distributed with its source code, making it available for use, modification and distribution under its original rights. Source code is the part of software that is invisible to most computer users; it is the code that computer programmers use to control how a program or application behaves. Programmers with access to the source code can alter the program by adding, changing, or fixing parts that don't work properly. OSS typically includes a license that allows programmers to modify the software to best suit their needs and control how the software is distributed.
How open-source software works
OSS is shared in public repositories, granting access to anyone who wants to work on the source code. However, open source software often comes with a distribution license, which specifies how people can interact, modify, and share OSS.
Once changes are made to the source code, OSS should represent these changes and what method was used to make them. Also, depending on the license, the resulting OSS may or may not need to be free. Therefore, most open source software is free, but some require an upfront or subscription fee.
How is open source used in software development?
The open source development model is the process used by open source community projects to develop open source software. The software is then released under an open source license, so anyone can view or modify the source code.
Many open source projects are hosted on GitHub, where you can access repositories or contribute to community projects. Linux, Ansible, and Kubernetes are examples of popular open source projects.
What is the value of open source?
There are many reasons why people choose open source over proprietary software, but the most common reasons are:
Peer Review: Since the source code is freely accessible and the open source community is very active, open source code is actively reviewed and improved by peer programmers. Think of it as dynamic code, not closed and stagnant code.
Transparency: Need to know exactly what types of data are moving where, or what types of changes have occurred in the code? Open source allows you to check and trace yourself instead of relying on vendor promises.
Reliability: Proprietary code relies on a single author or company controlling that code to keep it updated, patched, and working. Open source code outlives its original authors because it is constantly updated through an active open source community. Open standards and peer review ensure that open source code is tested appropriately and often.
Flexibility: Because of the emphasis on modification, you can use open source code to solve problems unique to your business or community. You're not locked into using the code in any one particular way, and you can rely on community help and peer reviews when implementing new solutions.
Lower costs: Using open source code itself is free - when you use a company like Red Hat, what you pay for is support, security hardening, and help managing interoperability.
No vendor lock-in: User freedom means you can take your open source code anywhere, anytime, and use it for anything.
Open collaboration: The presence of an active open source community means you can find help, resources, and perspectives that transcend one interest group or one company.
I hope this article will help you to learn what is an open source software and how is open source used in software development. With the modification and improvement of many parties, open source software inevitably has quality, performance and security defects. However, a broad base of code contributors also means that bugs can be identified and fixed more quickly.
