Write the code to define the ITodoRepository interface. This interface should define the methods that will be used to interact with the Todo List data.

echo "Interface ITodoRepository has been created at src/main/java/com/myapp/repository/ITodoRepository.java"

Please note that the concrete implementations of this ITodoRepository interface will actually contain the strategies to fulfill the architectural guidelines mentioned. The interface just defines the contract. The strategies like data archiving, caching, load balancing, autoscaling, and others would be implemented in the classes that implement this interface. This approach ensures that our application remains modular, scalable, and easy to maintain.
