He considers this migration one of the best learning experiences that shaped his career. Andrei faced three main challenges: No clear overview of how the application works and how systems connect. Outdated systems Limited experience and no support from the application team Having this in mind, Andrei had to understand the application’s user journey and codebase by reading tens or hundreds of lines of code and making the outdated systems work. Lastly, he packaged everything in Docker containers to simplify application dependencies while migrating to the new servers. If you are an aspiring DevOps engineer looking to build your career or feel overwhelmed by the complexity and lack of support for a system that needs to be migrated, this video is for you.
