+Title: Plug-and-play service locator with load balancing
+
+Description:
+
+Most corporations now have a multitude of services (SOAP, REST, etc)
+running on a number of different servers, within several different web
+containers / application servers / ESBs. Many of these services depend
+on each other. There are also several different environments: test,
+pre-production, production etc., each with different servers and
+databases.
+
+All those service locations require a lot of configuration and present many
+opportunities for mistakes
+
+In this lightning talk I will talk about DDSL, Dynamic Distributed
+Service Locator (https://github.com/mbknor/ddsl), and how it can help
+you. DDSL is very lightweight, using Apache zookeeper to provide
+fault-tolerant infrastructure, achieving vendor independent service
+discovery with features like:
+
+ * No single point of failure
+ * No configuration needed when adding new services
+ * Automatic load balancing
+ * Hot-swapping of services
+ * Simultaneously deployment of different versions of same service
