What is Free Service Mesh?

A service mesh is an infrastructure layer that manages the communication between microservices within a distributed application. It provides features such as load balancing, service discovery, traffic routing, security (such as encryption and authentication), and observability (monitoring and logging) without requiring changes to the application code. Service meshes are typically used in microservices architectures to ensure that services can communicate efficiently and securely across a network. They help with managing complex communication patterns, ensuring reliable and secure service-to-service interactions, and providing valuable insights into the health and performance of the services. Service meshes are often integrated with container orchestration platforms. Compare and read user reviews of the best Free Service Mesh currently available using the table below.

    Connect, secure, control, and observe services. Istio’s traffic routing rules let you easily control the flow of traffic and API calls between services. Istio simplifies configuration of service-level properties like circuit breakers, timeouts, and retries, and makes it easy to set up important tasks like A/B testing, canary rollouts, and staged rollouts with percentage-based traffic splits. It also provides out-of-box failure recovery features that help make your application more robust against failures of dependent services or the network. Istio Security provides a comprehensive security solution to solve these issues. This page gives an overview on how you can use Istio security features to secure your services, wherever you run them. In particular, Istio security mitigates both insider and external threats against your data, endpoints, communication, and platform. Istio generates detailed telemetry for all service communications within a mesh.
