JClouds S3

Summary

jclouds-s3's goal is to be straight-forward and infrastructure friendly. By straight-forward, it presents a Map-like interface to S3. By infrastructure-friendly, it works well in restricted environments and also can take advantage of less restricted ones.

Easy interface

        S3Context context = S3ContextFactory.createS3Context(accesskeyid, secretkey);
        S3Bucket bucket = new S3Bucket();
        bucket.setName("adrian");
        Map map = context.createInputStreamMap(bucket);
          // do work
        context.close();

Support for Google App Engine

Google App Engine for Java restricts things like spawning threads and making network connections. JClouds provides a connection module that works in GAE (jclouds-gae).

• here is no api change, only a slight difference in how you create your context

        S3Context context = S3ContextFactory.createS3Context(accesskeyid, secretkey,
                new URLFetchServiceClientModule());

More Power?

jclouds-s3 can be configured with a server-grade module (jclouds-s3nio) that takes advantage of thread pools and non-blocking io. Use this module if you are not using Google App Engine and you need more power.

• Again, it is really easy to configure this:

        S3Context context = S3ContextFactory.createS3Context(accesskeyid, secretkey,
                new S3HttpNioConnectionPoolClientModule());
