Key takeaways

Despite the challenges, enterprises keep running legacy applications for many reasons. Working on one is a common task, most professionals will at some point, so architects should know how to oversee one effectively.
Legacy systems routinely need changes (bug fixes, new features). To make those changes safer and easier, architects refactor them for maintainability.
Architects also improve legacy systems by migrating them to the cloud and modernizing build and deployment processes.
The next chapter shifts from technical topics to the soft skills an architect needs when moving from developer to architect.
