What is a benefit of modular services in microservices architecture?

The benefit of modular services in microservices architecture lies in their ability to allow independent development and deployment. This characteristic enables different teams to work on various services simultaneously without being dependent on each other's progress. As a result, changes can be made to one service without needing to disrupt the functionality of others, leading to faster release cycles and more agile responses to market demands or technological advancements.

In a microservices setup, each service is encapsulated and focuses on a specific business function, which allows teams to utilize various technologies and programming languages best suited for each service. This modularity enhances the overall system's flexibility and scalability, making it easier to adapt or scale specific components as needed based on usage patterns or performance requirements.

While managing modular services does come with its own challenges, such as increased complexity in orchestration and communication between services, these challenges are often outweighed by the significant benefits associated with independent deployment and development capabilities.
