Explain the concept of microservices and their benefits in a DevOps architecture.

Microservices is an architectural approach where an application is divided into smaller, loosely coupled services that can be developed, deployed, and scaled independently. In DevOps, microservices align well with the continuous delivery model, allowing teams to focus on specific components and release them rapidly. This architecture enhances agility, fault isolation, and scalability, as changes to one microservice don't necessarily impact others.
