What aspect of hybrid applications does a service mesh enhance?

A service mesh enhances communication between microservices in hybrid applications. In a microservices architecture, numerous small, independently deployable services interact with one another over a network. A service mesh facilitates this communication by providing a dedicated infrastructure layer that manages and monitors the interactions between these services.

By implementing a service mesh, organizations can improve service discovery, traffic management, and security features such as mutual TLS for encrypting the communication between microservices. It also adds capabilities for observability, enabling tracking and tracing service requests, which can be critical in diagnosing issues and ensuring reliable communication within complex microservices environments.

While cost management, user interface design, and data storage solutions are important aspects of application development and operation, they do not directly correlate with the primary functions of a service mesh. Instead, the service mesh's core purpose is to streamline and enhance the communication fabric that allows microservices to operate more effectively within a hybrid application architecture.
