Open Source
Open source is not just about “free”. Above all it means the key part of the technology is not owned by a single vendor — the source code is available, there is a wider market of specialists, and the system can be handed over. In practice this comes up most often around Drupal and hosting on your own server .
Critical External Dependency: When a Vendor Becomes a Risk

Picture an e-shop that has been running on a single platform for several years. It holds the website, the products, the orders, the stock, and the link to accounting.
