Easegress
Easegress is an open-source traffic orchestration system (API gateway / service mesh / ingress controller) for cloud-native and microservices environments.
- Hypertext Transfer Protocol (HTTP) and Transmission Control Protocol (TCP) reverse proxy, load balancing, and traffic management (application networking).
- Ingress gateway for Kubernetes and other platforms, including routing, rate limiting, and circuit breaking (API gateway).
- Service mesh-style traffic governance with canary releases, blue-green deployment, and traffic mirroring (service reliability).
- Pluggable pipeline model for custom filters, authentication, observability, and protocol handling (extensibility).
- High-availability, horizontally scalable control plane with cluster management and configuration coordination (infrastructure orchestration).
More About Easegress
Easegress is an open-source traffic orchestration framework (application networking) designed to manage north-south and east-west traffic in cloud-native architectures. It targets scenarios such as microservices, API-driven systems, and hybrid environments where organizations need consistent routing, resiliency policies, and governance for HTTP, TCP, and other protocols. The project focuses on providing an Application Programming Interface (API) gateway, ingress controller, and service mesh-style traffic control in a single, composable system.
At its core, Easegress offers reverse proxy, load balancing, and routing capabilities (API gateway) that support features such as path-based routing, header-based routing, and weighted traffic distribution. It includes functions for rate limiting, request throttling, retries, timeouts, and circuit breaking (service reliability) that allow teams to control how traffic flows to backend services under varying load and failure conditions. These capabilities are exposed through declarative configuration and APIs, enabling integration into automated deployment pipelines and GitOps workflows.
Easegress implements an ingress gateway role for Kubernetes and other platforms (ingress controller), enabling external client traffic to reach internal services through a unified entry point. It supports canary releases, blue-green deployments, and traffic mirroring (progressive delivery) by splitting or duplicating traffic between multiple service versions based on weights or rules. This allows operators and development teams to introduce changes with controlled exposure, observe behavior, and roll back by adjusting routing configurations rather than modifying application code.
The project uses a pipeline-based architecture (extensibility) in which traffic passes through configurable filters that can handle authentication, authorization, observability, transformation, and protocol-specific processing. This model allows extension through custom filters and integration points, so enterprises can connect Easegress with identity providers, logging and metrics systems, or domain-specific middleware. The framework also exposes management APIs and dashboards for traffic visibility and operational management.
Easegress is built for high availability and scalability (infrastructure orchestration), with a cluster architecture that coordinates configuration and state across multiple nodes. It can run on Kubernetes or directly on virtual machines or bare metal, supporting deployment in on-premises (on-prem), cloud, or hybrid settings. In enterprise environments, it is used to standardize API exposure, protect backend services with policy-based controls, and provide a central layer for observability and traffic governance. Within a technical taxonomy, Easegress fits into categories such as API gateway, Kubernetes ingress controller, and service mesh traffic manager, and it interacts with broader cloud-native stacks that require reliable and extensible traffic control.
