Answer: A, C

Explanation:

Microservices are a design principle for cloud-native applications, where each application is composed of a set of small, independent, and loosely coupled services that communicate with each other through well-defined interfaces1. Microservices have the following characteristics2:

Microservices are chained in order to build an application, meaning that they are connected by a network and exchange messages or data to perform a specific function or task.

Microservices are differentiated by function, meaning that each microservice has a single responsibility and performs a distinct function within the application.

Microservices are derived from monolithic applications, meaning that they are created by breaking down a large and complex application into smaller and simpler pieces that can be developed, deployed, and scaled independently.

Microservices are scalable and resilient, meaning that they can handle variable workloads and recover from failures without affecting the whole application.

Therefore, the correct statements are A and C, while B and D are incorrect.
