Overview:
 
jclouds is an open source framework that helps you get started in the cloud
and reuse your java and clojure development skills. Our api allows you to 
freedom to use portable abstractions or cloud-specific features.
 
our current version is 1.0-beta-5
our dev version is 1.0-SNAPSHOT
 
our compute api supports: ec2, gogrid, rackspace, rimuhosting, vcloud, terremark, 
                          hosting.com, bluelock
our blobstore api supports: s3, rackspace, azure, atmos online, att synaptic,
                          transient (in-memory)
 
BlobStore Example (Java):
  // init
  context = new BlobStoreContextFactory().createContext(
                  "s3",
                  accesskeyid,
                  secretaccesskey);
  blobStore = context.getBlobStore();
 
  // create container
  blobStore.createContainerInLocation(null, "mycontainer");
  
  // add blob
  blob = blobStore.newBlob("test");
  blob.setPayload("testdata");
  blobStore.putBlob("mycontainer", blob);

BlobStore Example (Clojure):
  (use 'org.jclouds.blobstore)

  (with-blobstore ["azureblob" account encodedkey]
    (create-container "mycontainer")
    (upload-blob "mycontainer" "test" "testdata"))

Compute Example (Java):
  // init
  context = new ComputeServiceContextFactory().createContext(
                  "ec2",
                  accesskeyid,
                  secretaccesskey,
                  ImmutableSet.of(new Log4JLoggingModule(),
                                  new JschSshClientModule()));
  client = context.getComputeService();
 
  // define the requirements of your node
  template = client.templateBuilder().osFamily(UBUNTU).smallest().build();
 
  // these nodes will be accessible via ssh when the call returns
  nodes = client.runNodesWithTag("mycluster", 2, template);

Compute Example (Clojure):
  (use 'org.jclouds.compute)

  ; create a compute service using ssh and log4j extensions
  (def compute 
    (compute-service "terremark" "user" "password" :ssh :log4j))

  ; use the default node template and launch a couple nodes
  ; these will have your ~/.ssh/id_rsa.pub authorized when complete
  (with-compute-service [compute]
    (run-nodes "mycluster" 2))
