Spring Cloud facilitates these styles of development in a number of specific ways.
The starting point is a set of features to which all components in a distributed system need easy access.</simpara>
<simpara>Many of those features are covered by <link xl:href="https://projects.spring.io/spring-boot">Spring Boot</link>, on which Spring Cloud builds. Some more features are delivered by Spring Cloud as two libraries: Spring Cloud Context and Spring Cloud Commons.

Spring Cloud Context provides utilities and special services for the <literal>ApplicationContext</literal> of a Spring Cloud application (bootstrap context, encryption, refresh scope, and environment endpoints). Spring Cloud Commons is a set of abstractions and common classes used in different Spring Cloud implementations (such as Spring Cloud Netflix and Spring Cloud Consul).</simpara>
<simpara>If you get an exception due to "Illegal key size" and you use Sun&#8217;s JDK, you need to install the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files.

<simpara>Spring Cloud Commons provides the <literal>@EnableDiscoveryClient</literal> annotation.
This looks for implementations of the <literal>DiscoveryClient</literal> interface with <literal>META-INF/spring.factories</literal>.
Implementations of the Discovery Client add a configuration class to <literal>spring.factories</literal> under the <literal>org.springframework.cloud.client.discovery.EnableDiscoveryClient</literal> key.
Examples of <literal>DiscoveryClient</literal> implementations include <link xl:href="https://cloud.spring.io/spring-cloud-netflix/">Spring Cloud Netflix Eureka</link>, <link xl:href="https://cloud.spring.io/spring-cloud-consul/">Spring Cloud Consul Discovery</link>, and <link xl:href="https://cloud.spring.io/spring-cloud-zookeeper/">Spring Cloud Zookeeper Discovery</link>.</simpara>

<simpara>By default, implementations of <literal>DiscoveryClient</literal> auto-register the local Spring Boot server with the remote discovery server.
This behavior can be disabled by setting <literal>autoRegister=false</literal> in <literal>@EnableDiscoveryClient</literal>.</simpara>
