With API endpoint discovery and enhanced security, the service-to-service communication in service mesh has reduced latency which leads to better application performance. From the security perspective, you get protection against third-party attacks, flexible access controls, mutual Transport Layer Security (mTLS), and auditing tools. There are much easier traffic control options available that help in various deployments and testing like canary deployments, A/B testing, etc. Developers don’t have to deal with the complexities of working with microservices directly and all is abstracted/taken care of by a service mesh.
