A company exposes its microservices to external partners via APIs. They need to enforce rate limits, authenticate API consumers, and provide a unified interface to multiple backend services. Which solution should they implement?

A service mesh with sidecar proxies

A VPN tunnel for partners to access the internal network

A direct connection from partners to each microservice

An API management platform with a gateway

Why is statelessness an important design principle for cloud-native applications?

It allows any instance to handle any request, simplifying scaling and load balancing.

It makes the application run faster by reducing network calls.

It eliminates the need for databases in the application.

It ensures that the application never loses data.

A microservices application has many services that need to communicate with each other. The operations team wants to implement circuit breaking and retry logic to handle transient failures, but they do not want to modify each service's code. Which approach should they take?

Implement a service mesh with traffic management policies

Add a library to each service for retry and circuit breaking

Configure a load balancer to retry failed requests

Use an API gateway to handle retries for all internal calls

What is the primary purpose of a service mesh in a microservices architecture?

To store data for microservices.

To compile microservices into executable binaries.

To manage and secure communication between microservices.

To replace the need for container orchestration.

A company wants to expose a set of backend microservices to mobile clients. They need to handle authentication, rate limiting, and request routing to the appropriate service. They also want to monitor API usage. Which solution should they use?

A service mesh with sidecar proxies

An API gateway with integrated security and analytics

A VPN for mobile clients to access the internal network

A direct connection from mobile clients to each microservice
