## Start a service and set the proxy

- Client will send all requests to the proxy
- If MICRO_PROXY is set the client looks up the registry for the proxy
- If MICRO_PROXY_ADDRESS is set it calls the proxy directly

```
MICRO_PROXY=go.micro.proxy run service
```

## Start the proxy and specify the router

- Proxy will call the router to get routes for a service
- Same variable definitions as proxy for the client
- Proxy will receive equivalent to selector Next nodes

```
MICRO_ROUTER=go.micro.router run proxy
```

## Start the router with network gateway/address

- Router maps local routes to the network gateway
- Router gossips with other routers to advertise routes
- Router gives proxy next hop as network gateway for things outside local network

```
MICRO_NETWORK=go.micro.network run router
```

## Start the network and join other network nodes

- Network is gateway with embedded proxy and router
- Network receives requests from proxy and uses router to forward to next node

```
MICRO_NETWORK=micro.mu run network
```
