This technical question assumes that you are familiar with Microservices Architecture. When preparing for an interview, you should research the organization to determine its technologies and programming methodologies. Knowing this will help you prepare for questions like these. If you're not familiar with the topic the interviewer is asking you about, it is okay to admit this, as long as you state how you would go about acquiring the knowledge or the skills needed.

"There are several reasons you would employ a microservices architecture when developing software. The first is that microservices are flexible and easily adapt to multiple frameworks and technologies. Another reason is that when one process fails within a microservices environment, the others are not affected. Microservices are also applicable across all sizes of organizations, and they can be deployed quickly when needed."

A microservices architecture involves a suite of small separate services (each running its own process) communicating and working together to provide overall application functionality. Individual services are lightweight and can have independent implementations, and communicate via HTTP protocol. This architecture requires minimum central administration since the services can be designed and implemented independently, and all that matters is the API they expose. A microservices architecture provides modularity; each service is independently and automatically deployable and is more likely to fail independently. Amazon famously adopted this approach early on to great success and has been able to externalize these individual services via AWS.
