What is a primary benefit of using microservices?

A primary benefit of using microservices is better scalability. Microservices architecture allows different components of an application to be developed, deployed, and scaled independently of one another. This means that organizations can allocate resources more efficiently by scaling only the services that require additional capacity rather than the entire application.

For example, if a specific service experiences higher demand, it can be scaled up without affecting the other services, which could remain unaffected by the workload. This dynamic allocation of resources leads to improved performance and responsiveness of applications, particularly during peak usage times. Additionally, the ability to isolate and improve individual services promotes innovation, as teams can deploy updates and changes with greater agility.

The other options do not reflect the benefits associated with microservices. Higher costs and increased complexity can be consequences of adopting a microservices architecture, but they do not highlight the advantages. A monolithic structure is contrary to the concept of microservices, as it describes a different approach to building applications where all components are tightly coupled.
