This tutorial shows you how to write contract-first Web services, that is, developing web services that start with the XML Schema/WSDL contract first followed by the Java code second. Spring-WS focuses on this development style, and this tutorial will help you get started. Note that the first part of this tutorial contains almost no Spring-WS specific information: it is mostly about XML, XSD, and WSDL. The second part focusses on implementing this contract using Spring-WS .

Backing up data regularly should be one of the most important tasks of every computer user; Yet only a minority is doing it thoroughly and regularly. The rest is flirting with disaster as there are numerous incidents that can delete data on computer systems. The most common ones are hardware failures, which can mean damaged hard drives but also (partially) unreadable CDs or DVDs, computer virus attacks but also human error. If you have ever met someone who partitioned the wrong hard drive you know that the latter can be cause for great frustration.

Eucalyptus – Elastic Utility Computing Architecture Linking Your Programs To Useful Systems – is an open-source software infrastructure for implementing "cloud computing" on clusters. The current interface to Eucalyptus is compatible with Amazon's EC2, S3, and EBS interfaces, but the infrastructure is designed to support multiple client-side interfaces. Eucalyptus is implemented using commonly available Linux tools and basic Web-service technologies making it easy to install and maintain.

AppScale is a platform that allows users to deploy and host their own Google App Engine applications. It executes automatically over Amazon EC2 and Eucalyptus as well as Xen and KVM. It has been developed and is maintained by the RACELab at UC Santa Barbara.
