The component uses +http://code.google.com/p/jclouds[jclouds] which is + + a library that provides abstractions for blobstores and compute +services. + +*ComputeService* simplifies the task of managing machines in the cloud. +For example, you can use ComputeService to start 5 machines and install +your software on them. + + *BlobStore* simplifies dealing with key-value providers such as Amazon +S3. For example, BlobStore can give you a simple Map view of a +container. + +The camel jclouds component allows you to use both abstractions, as it +specifes two types of endpoint the JcloudsBlobStoreEndpoint and the +JcloudsComputeEndpoint. You can have both producers and consumers on a +blobstore endpoint but you can only have producers on compute endpoints. + +Maven users will need to add the following dependency to their `pom.xml` +for this component: + +[source,xml] +------------------------------------------------------------ +<dependency> + <groupId>org.apache.camel</groupId> + <artifactId>camel-jclouds</artifactId> + <version>x.x.x</version> + <!-- use the same version as your Camel core version --> +</dependency> +------------------------------------------------------------ + +[[jclouds-Configuringthecomponent]] +Configuring the component +^^^^^^^^^^^^^^^^^^^^^^^^^ + +The camel jclouds component will make use of multiple jclouds blobstores +and compute services as long as they are passed to the component during +initialization.
