Migration to Open Source Systems

Software and technology are shaping every aspect of our lives. As we utilize these technologies, the manner in which software is created and shared plays a pivotal role.

Open-Source Software (OSS) refers to a software development model based on the freedom of making the source code accessible to everyone, allowing anyone to inspect, modify, and distribute it. This paradigm enables software creation, utilization, and distribution to occur in a more open, transparent, and collaborative manner. Backed by hundreds of contributors, open-source software evolves at an extraordinary pace. Recent advancements in Big Data, Cloud Computing, and Artificial Intelligence (AI) notably demonstrate the powerful impact of the Open-Source philosophy.

Open-source solutions offer organizations and enterprises the freedom to adapt and customize software seamlessly. Providing direct access to source code empowers users to tailor and enhance application functionality according to their specific operational needs, granting organizations greater overall control.

To manage budgets effectively, organizations increasingly lean toward cost-efficient solutions. The royalty-free nature of open-source software enables institutions and enterprises to achieve substantial savings on licensing costs.

Furthermore, open-source software provides organizations with total sovereignty over their data, offering economic, political, and technical independence. It ensures freedom from arbitrary price hikes, safeguards against hidden backdoors, and delivers long-term sustainability.

Step Forward with Open Source!

By embracing the core philosophy of sharing and collaboration inherent in open source, enterprises, universities, and public institutions can exchange experiences and collaborate on joint initiatives with peer organizations.

Open Source Prioritizes Security and Continuous Improvement

Open-source software is backed by expansive developer and user communities. These global communities ensure that software is continuously updated and security vulnerabilities are rapidly remediated.

FOSS Migration Analysis and Roadmap Report

The adoption of open-source software by public institutions yields numerous benefits, including cost efficiency, flexibility, security, and enhanced collaboration. However, successfully managing this transition requires strict focus on planning, training, and compliance processes. Leveraging open-source software can significantly elevate public service quality and play a vital role in establishing a sustainable technology infrastructure.

Safeguarding Our Software Independence

To maximize the strategic benefits of open-source software for Türkiye and expand Free and Open-Source Software (FOSS / AKKY) adoption across public institutions, Presidential Circular No. 2023/13 on the "Use of Free and Open-Source Software in the Public Sector" issued by the Presidency of the Republic of Türkiye Digital Transformation Office was published in the Official Gazette No. 32263 on July 29, 2023, and officially entered into force.

Pursuant to the aforementioned Circular, public institutions are required to prepare a "FOSS Migration Analysis and Roadmap Report" in accordance with the official template available online, taking into consideration the "Free and Open-Source Software Migration Analysis Guide" prepared by TÜBİTAK-ULAKBİM. This report must be submitted to the Digital Transformation Office of the Presidency within nine (9) months from the publication date of the Circular.
