Which of the following describes a benefit of using microservices architecture?

The scalability of individual services is a significant benefit of using microservices architecture. In a microservices architecture, applications are constructed as a collection of loosely coupled services, each responsible for a specific function. This modular approach allows each service to be developed, deployed, and scaled independently from the others.

When a specific service experiences high demand, it can be scaled out without needing to scale the entire application. This targeted scaling is more efficient, as it optimizes resource utilization based on the needs of each service. In contrast, monolithic architectures typically require scaling the whole application, which can lead to unnecessary resource use and higher costs.

Furthermore, this architecture supports varying scaling requirements for different services. For example, a service handling user authentication might need to handle more requests than a service dealing with notifications. By allowing individual services to scale independently, microservices architectures can provide better performance, flexibility, and cost-effectiveness in resource management.
