Microservices architecture is best described as:
- A software architecture exclusively used for database management
- A software architecture that structures an application as a collection of small, loosely coupled services
- A software architecture where a single, massive service handles all application functionality
- A software architecture where monolithic systems are preferred
Microservices architecture is a design approach in which a software application is structured as a collection of small, loosely coupled services that communicate with each other through APIs. This promotes flexibility and scalability.
