== Providing dependencies for cloud discovery protocols

To use `aws.S3_PING`, `GOOGLE_PING2`, or `azure.AZURE_PING` cloud discovery protocols, you need to provide dependent libraries to {brandname}.

.Procedure

ifdef::embedded_caches[]
* Add the artifact dependencies to your project `pom.xml`.
endif::embedded_caches[]

ifdef::remote_caches[]
. Download the artifact JAR file and all dependencies.
. Add the artifact JAR file and all dependencies to the `{server_home}/server/lib` directory of your {brandname} Server installation.
+
For more details see the link:https://access.redhat.com/solutions/6048651[Downloading artifacts for JGroups cloud discover protocols for Data Grid Server] ({RedHat} knowledgebase article)
endif::remote_caches[]

You can then configure the cloud discovery protocol as part of a JGroups stack file or with system properties.
