This month we welcome Eric Lavigne with an evening focused on jclouds:
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 freedom to use portable abstractions or cloud-specific features. We support many clouds including Amazon, VMWare, Azure, and Rackspace.

Here's how we help you get started:

1. Simple interface Instead of creating new object types, we reuse concepts like maps so that the programming model is familiar. In this way, you can get started without dealing with REST-like apis or WS.
2. Runtime portability We have plugins that allow you to operate in restricted environments like Google App Engine and Android.
3. Deal with web complexity Network based computing introduces issues such as transient failures and redirects. We handle this for you.
4. Unit testability Writing tests for cloud endpoints is difficult. We provide you with Stub connections that simulate a cloud without creating network connections. In this way, you can write your unti tests without mocking complexity or the brittleness of remote connections.
5. Performance We have a pluggable engine which gives you more horsepower when you need it. Our high performance engine uses executors and nio to scale efficiently.
