 == Circuit Breaker: Hystrix Clients
 
+Example boot app:
+
+```
+@Configuration
+@EnableAutoConfiguration
+@EnableHystrix
+public class Application {
+
+    public static void main(String[] args) {
+        new SpringApplicationBuilder(Application.class).web(true).run(args);

+    }

 == Circuit Breaker: Hystrix Dashboard
 
 === Turbine
 
 == Declarative REST Client: Feign
 
+Example application.yml:
+
+```
+spring:
+  cloud:
+    client:
+      serviceIds:
+        - stores
+```
+
+Example spring boot app
+```
+@Configuration
+@ComponentScan
+@EnableAutoConfiguration
+@EnableEurekaClient
+public class Application extends FeignConfigurer {
+    @Bean
+    public StoreClient storeClient() {
+        //loadBalance plugs Feign into ribbon.  feign() works without load balancing.
+        return loadBalance(StoreClient.class, "http://stores");
+    }
+
+    public static void main(String[] args) {
+        SpringApplication.run(Application.class, args);
+    }
+
+}
+```
+
+StoreClient.java
+```
+public interface StoreClient {
+    @RequestMapping(method = RequestMethod.GET, value = "/stores")
+    Stores getStores();
+
+    @RequestMapping(method = RequestMethod.POST, value = "/stores/{storeId}", consumes = "application/json")
+    Store update(@PathParameter("storeId") Long storeId, Store store);
+}
+```
+
 == Client Side Load Balancer: Ribbon
 
+Example application.yml:
+
+```
+spring:
+  cloud:
+    client:
+      serviceIds:
+        - stores
+```
+
+Usage of `LoadBalancerClient` directly:
+
+```
+public class MyClass {
+    @Autowired
+    private LoadBalancerClient loadBalancer;
+
+    public void doStuff() {
+        //"stores" in choose() must match a service in spring.cloud.client.serviceIds
+        ServiceInstance instance = loadBalancer.choose("stores");
+        URI storesUri = URI.create(String.format("http://%s:%s", instance.getHost(), instance.getPort()));
+        // ... do something with the URI
+    }
+}
+```
+
+Indirect usage via `RestTemplate`.  Notice the `stores` hostname part, must match a service id in spring.cloud.client.serviceIds:
+
+```
+public class MyClass {
+    @Autowired
+    private RestTemplate restTemplate;
+
+    public String doOtherStuff() {
+        String results = restTemplate.getForObject("http://stores/stores", String.class);
+        return results;
+    }
+}
+```
