方案一 基于客户端负载均衡
upstream grpc_servers { server localhost:3001; server localhost:3002;}server { listen 5000 http2; access_log logs/access.log main; location / { grpc_pass grpc://grpc_servers; }}
3001
方案三基于envoy应用代理
watch
ingress-gateway
localhost:3001(grpc)
localhost:3000(grpc)
etcd/consul
nginx/envoy/linkerd
方案二基于nginx/envoy/linkerd统一代理
方案四基于istio的sidecar代理
localhost:3002(grpc)
grpc:3000
