A service mesh is a network of microservices that communicates with each other to form a complete application. A service mesh typically includes a proxy server that routes communication between the microservices, as well as other services such as Load Balancing, service discovery, and monitoring.
The main purpose of a Service Mesh is to make it easier to manage and monitor communication between microservices. In a microservice-based architecture, each service has its own unique functionality and is typically developed and maintained by a separate team. This can make it difficult to ensure that the different services are communicating with each other correctly, and can also make it challenging to monitor the overall health and performance of the application.
A Service Mesh provides a central location for managing and monitoring communication between the microservices. This allows developers to focus on the functionality of their individual services, without having to worry about the underlying communication infrastructure. In addition, a Service Mesh can provide features such as automatic retries and circuit breakers, which can help to improve the reliability and resilience of the overall application.
Overall, a Service Mesh is a useful tool for managing and monitoring communication in a microservice-based architecture. It can help to improve the reliability and performance of the application, and can also make it easier for developers to focus on the functionality of their individual services.
