## What it is
Nepxion Discovery is a cloud-native microservice governance framework for Spring Cloud and Spring Cloud Alibaba. It provides blue-green and gray (canary) releases, routing, rate limiting, circuit breaking, degradation, isolation, tracing, traffic dyeing, and failover capabilities.

## Use cases
- implement blue-green deployments in spring cloud
- canary release traffic routing for microservices
- gray release with nacos and spring cloud alibaba
- add rate limiting and circuit breaking to spring cloud services
- trace and dye traffic across microservices
- route requests based on metadata in a service mesh
- failover and multi-active deployment for microservices

## When to choose
- you run Spring Cloud or Spring Cloud Alibaba microservices and need fine-grained release and traffic governance
- you use Nacos, Apollo, Sentinel, or SkyWalking and want integrated gray release and tracing
- you need blue-green/canary deployments with routing, isolation, and failover in Java

## When to avoid
- your stack is not Java/Spring Cloud based
- you use a service mesh like Istio and prefer platform-level traffic management
- you need a simple app with no microservice release complexity

## Facets
- artifact type: framework
- maturity: active
- function: microservices, routing, rate-limiting, tracing, monitoring, middleware, service-discovery, api-gateway
- domain: microservices, cloud-computing, backend
