An organization wants to refactor their application by using a microservices architecture when migrating to the cloud. Which benefit would this action provide?

Microservices allow each service to be scaled independently based on demand, so high-traffic components can be scaled out without scaling the entire application. This architecture also allows teams to deploy, update, and maintain individual services without affecting others, improving development velocity and resource efficiency. These properties make the refactored application more scalable and operationally efficient than a monolith.

Refactoring by definition requires code changes to decompose the monolith into separate services with well-defined interfaces.

The fastest migration path to the cloud is a 'lift and shift' (rehost) approach, which moves the application with minimal changes rather than refactoring it.

PCI-DSS compliance depends on specific security controls, network segmentation, encryption, and audit practices, not on the choice of microservices architecture.
