Build a hybrid OpenStack environment on POWER8 and Intel x86
IBM Bluemix is a platform as a service (PaaS) based on the Cloud Foundry open source project that promises to deliver enterprise-level features and services that are easy to integrate into cloud applications. POWER8 is IBM's newest processor. Cloud Foundry applications written in a variety of runtimes such as Node.js, Ruby, and the Java programming language can now run on POWER8. The first step toward setting up a hybrid Cloud Foundry environment on POWER8 and Intel x86 systems is to construct a hybrid OpenStack environment. OpenStack is a popular open source infrastructure as a service (IaaS) project promoted by IBM and other industry leaders. This tutorial presents a process to set up an OpenStack compute node on PowerKVM and connect it to the Intel x86 OpenStack controller node. In future tutorials in this series, we will describe how to enable BOSH automation to deploy a Cloud Foundry Droplet Execution Agent (DEA) on top of this hybrid OpenStack environment.

Converting COM request to web service request
Since its introduction, web service has become a standard mechanism for integration between applications. However, there are many applications written in languages that do not provide a strong support for web service - for example Visual C++ V6.0 or Visual Basic V6.0. One approach to enable these applications is to have an adaptor that can convert a request into a web service call. This tutorial describes how to develop this adaptor implemented as a DCOM server using C#. It basically receives a COM request and forward the request to a web service endpoint. It also provides steps on how to make a COM request in C++ and shows steps on how to implement a Java web service. In short, it demonstrates how web service interoperability on the .NET and JEE platform can be achieved. C# code is developed using Microsoft Visual Studio, while the web services is developed using Rational Application Developer V7.5 and deployed on the WebSphere Application Server V7.0 test environment.

Develop a store locator application using IBM DB2 pureXML and ASP.NET
In this connected and open world, where data flows freely, you can find a vast amount of useful information on the Web. In the past, if you wanted to find the location of the nearest store for your favorite retailer, you probably looked it up in the telephone directory, found the company's phone number, called them, and asked for directions to their nearest outlet. This method is a recipe for getting lost, wasting time, and a general frustration for the customer. Today, however, this has all changed. Now you simply open your Web browser and visit the company's Web site, where you can usually find a "Store Locator" feature that will help you find the store nearest to you, and conveniently plot it on a map to make it easier to find.
