DIY NoSQL: Spinning up services with Whirr

Whether it's HBase, Cassandra or one of the many others, you've probably already heard about NoSQL. Perhaps you have a continuous test flow dependency, yet are concerned about learning curve or infrastructure required for the NoSQL store you need.

During this talk, you'll see how you can transform infrastructure clouds such as Amazon EC2 or GoGrid into your data cluster using Apache Whirr.

We'll start by reviewing cloud provisioning and how Whirr adds service management to the underlying jclouds ComputeService API. You'll then learn whirr syntax and how to use it from the commandline or via a Java API. Finally, we'll discuss patterns for workflow integration. When you leave, you'll know how to setup and use NoSQL stores with a lot less work.

Hands on Cloud Storage

You may have heard about cloud storage offerings such as Amazon S3, OpenStack or Microsoft Azure. While conceptually similar, these offerings have different apis and behaviour that place the "write once (run|test) anywhere" mantra at risk. The jclouds open source java and clojure library aims to eliminate cloud vendor lock-in, exposing easy to use, portable, and powerful APIs. Bring your laptop, armed with latest revs of Eclipse, git, and maven, and we'll walk through getting you setup to hack jclouds java or clojure BlobStore applications in a collaborative fashion.

During this workshop, you'll discover the value and key gotchas of cloud storage providers first hand. By the end of this session, you'll be writing testable code that creates and manages containers and blobs, and understand how cloud storage can fit into your architecture.

Portable Cloud Storage with jclouds

Key/value stores are the most common storage offerings in the cloud today. While conceptually similar, BlobStores present different programming models and consistency models that must be considered in application design. After this session, you'll understand these differences, and know how to use jclouds to avoid cloud lock-in and increase testability without restricting access to cloud-specific features.

We'll start by comparing public cloud services like Amazon S3 or Microsoft Azure and private cloud software like OpenStack Swift or Eucalyptus Walrus from a feature and code/API level. We'll then review java and clojure calls to the open source jclouds BlobStore API, abstracting away these differences. We'll finish with a review of integration patterns in production today you can consider while designing your cloud architecture.
