 Spring Cloud facilitates these styles of development in a number of specific ways.

 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>
