Open source & free software refers to software delivered with its source code and a license as to provide its users, freedom to run the software, study and modify its source code, and redistribute the software as it is or a modified version of it. These software may or may not involve cost. There are number of licenses used in an open source and free software such as MIT License, GNU General Public License, Apache License, BSD License, GNU Lesser General Public License, Artistic License, Mozilla Public License, etc.
Current economic status and cost effectiveness of open source & free software are influencing many enterprises to turn away from proprietary software. Open source and free software are being increasingly used in several functions. Despite of being dominated by proprietary software giants like Oracle, Microsoft and IBM, 25% of the database industry is captured by open software databases such as MySQL, PostgreSQL, MongoDB, among others. The larger part of the web server market is controlled by the Apache HTTP server and Nginx which are also open source. Apache Hadoop is the first name which comes to mind when dealing with Big Data analysis, because of its ability to store and quickly process large amount of data. Linux operating systems such as Red Hat Enterprise Linux (RHEL) and Ubuntu’s canonical are being preferred for servers and clouds as a server operating system.
While open source & free software are cost effective, flexible and customizable, concerns regarding security and readily available support are still afloat. Complexity of integrating open source with existing system, concerns about software quality and availability of skills to manage the software are some of the other challenges associated with open source and free software. In spite of these challenges adoption of open source & free software is expected to rise because of cost effectiveness drive by enterprises.
