The central principle of cloud engineering is adopting software engineering practices. Refactoring is a technique for making changes to code that improve maintainability, enhance performance, scalability, and security without changing its external behavior. In DevOps, refactoring often occurs with modern applications; however, we can apply those same techniques to cloud infrastructure with infrastructure as code.
Refactoring results in many advantages. First and foremost, the code is more readable and easier to understand for other team members –this aids in maintainability and well-organized code, providing a solid foundation for future releases. Overall, if done well, refactoring reduces complexity which makes future changes more efficient.
