This allows me to organize the application into distinct components, each responsible for a specific aspect of the application's functionality. By segmenting the application in this way, not only does it enhance maintainability by keeping related parts of the codebase together, but it also facilitates scalability. Each component can be scaled independently, in response to different demands, which is a critical factor in managing resources efficiently.
To further support scalability and maintainability, I adhere to the application factory pattern. This involves encapsulating the creation of the Flask app...
