What is the twelve-factor app methodology?

A set of 12 principles for building software-as-a-service applications that are portable, scalable, and deployable in cloud environments.

A testing methodology that uses 12 different test environments.

A framework for designing microservices that requires exactly 12 services per application.

A security standard that mandates 12 authentication factors.

A company has deployed a microservices application where services need to communicate securely and reliably. They want to add mutual TLS, traffic routing, and observability (metrics, logs, traces) without modifying the application code of each service. Which component should they introduce?

A load balancer in front of each service

A service mesh with sidecar proxies

An API gateway that handles all external requests

What is a key characteristic of serverless computing?

The cloud provider manages the underlying infrastructure and automatically scales resources in response to demand.

The developer must provision and manage virtual machines to run the code.

The code is compiled into a native binary that runs directly on the hardware.

The application runs only on dedicated physical servers owned by the customer.

Why is API management important in a cloud-native architecture?

It provides security, rate limiting, and analytics for APIs.

It replaces the need for authentication in the application.

It stores all application data in a central repository.

It compiles API definitions into executable code.
