Description: The Service Mesh Policy is a set of rules that govern the behavior of services within a service mesh, which is an infrastructure designed to facilitate communication between microservices in distributed applications. These policies allow defining how services interact with each other, managing aspects such as security, routing, observability, and resilience. Policies can include rules regarding the authentication and authorization of requests, rate limiting, error management, and the implementation of circuit breakers. By establishing these guidelines, organizations can ensure that their services operate efficiently and securely, minimizing the risk of failures and improving user experience. Additionally, policies can be applied centrally, simplifying the management and maintenance of the microservices infrastructure. In various environments, these policies are essential to ensure that services communicate effectively and meet the security and performance requirements set by the organization.
