What is Open Source?
The term "open source" refers to something that can be modified because its design is publicly accessible.
What is open source software?
Open source software is software whose source code is available for modification or enhancement by anyone.
Why open source?
Open source software is free to use, distribute, and modify. It has lower costs, and in most cases this is only a fraction of the cost of their proprietary counterparts.
Advantages of open Source:
More people can inspect the source code to find and fix a possible vulnerability.
With thousands, and often millions of users downloading, testing, and deploying an open source project, the code quality typically surpasses that of commercially-licensed software. And, with the source code readily available, developers have more options during their own testing and debugging cycles.
If you want the software to work slightly differently, you are able to change the code. If the code is issued under the Apache license you can redistribute your version, making it very ISV-friendly.
Because open source software is not owned by a vendor, you are never held hostage by a single, for-profit organization.
When your business uses proprietary software such as Microsoft Windows and Office, you are on a treadmill that requires you to keep upgrading both software and hardware ad infinitum. Open source software, on the other hand, is typically much less resource-intensive, meaning that you can run it well even on older hardware. It's up to you--not some vendor--to decide when it's time to upgrade.
Using an open source solution is not entirely free, but it is considerably less expensive than commercially-licensed solutions in several key areas.
7. Try Before You Buy
You can work with the fully functional product for as along as you like – even deploy and load test – before you make any financial investment.
Finally, Just imagine if everything we've learned throughout history was kept hidden or its use was restricted to only those who are willing to pay for it!
