Tars is a high-performance RPC framework that provides integrated service administration and flexible scheduling for distributed microservice architectures.
Tars addresses the complexity of building and managing distributed systems by combining several components into a unified platform. It centers on a name service and custom Tars protocol for efficient RPC communication, supplemented by an administration platform for deployment and management. The framework includes extensible protocol encoding and decoding, monitoring, statistics collection, and configuration management. This integrated approach allows developers to build reliable distributed applications without assembling multiple separate tools.
Tars suits teams building microservice architectures at scale who need both the RPC communication layer and operational tooling in one system. It is particularly relevant for organizations already invested in C++ infrastructure, though it also supports Java, Node.js, PHP, and Go. The framework runs on Linux, macOS, and Windows, making it accessible across different development and deployment environments. Teams should evaluate whether the integrated administration platform meets their needs compared to assembling RPC frameworks with separate service mesh or orchestration solutions.
The project maintains active development across multiple language implementations held in separate repositories, with each component versioned independently to allow parallel evolution. Documentation is comprehensive and available in multiple languages, supporting both new deployments and existing users. The project operates under Linux Foundation governance and maintains community engagement through multiple channels including mailing lists and discussion groups.
