Erda is an enterprise-grade, open-source cloud-native application platform built in Go that provides comprehensive DevOps, microservice governance, and multi-cloud management capabilities for Kubernetes environments. Created by Terminus, the platform is designed to simplify the development, deployment, monitoring, and troubleshooting of complex microservice applications across multiple cloud environments.
The core erda repository implements all RESTful and gRPC backend services through a microservice architecture, serving as the foundation for the entire platform. The platform's functional architecture encompasses several key components: DevOps capabilities for continuous integration and deployment, microservice governance features including Application Performance Management, comprehensive monitoring and log analysis, API gateway functionality, multi-cloud management, edge computing support, and FastData management. This modular approach allows organizations to manage application lifecycles efficiently while maintaining visibility across distributed systems.
Erda's architecture is distributed across multiple specialized repositories that work together as an integrated system. The erda-ui repository provides a React-based graphical user interface that communicates with backend services through RESTful APIs, enabling users to interact with the platform intuitively. The erda-proto repository defines communication protocols between backend services using Protocol Buffers, with plans to migrate additional service protocols to this standardized approach. The erda-infra repository implements a lightweight microservices framework in Go that provides middleware providers such as Redis, Kafka, and etcd, allowing developers to build module-driven applications rapidly. Supporting repositories include erda-actions for pipeline action definitions, erda-addons for middleware and third-party service configurations, and specialized tools like erda-analyzer for metrics aggregation, erda-java-agent for APM functionality, and kubeprober for Kubernetes cluster diagnostics.
The platform's vision centers on enabling organizations to build any application, deploy anywhere, and monitor anything, reflecting its comprehensive approach to modern application management.
Erda supports flexible deployment options through both single-node and multi-node setups, with installation guidance provided through Docker-based quick start procedures and Helm-based installation guides for production environments. The platform is distributed under the Apache 2.0 license and maintains active community engagement through multiple channels including email, Twitter, and regional communication platforms like WeChat and DingTalk.
