Windows Communication Foundation (WCF) enables disconnected work between clients and services. The client posts messages to a queue and the service processes them later. Such interaction permits a different programming model from the default request/response pattern, enabling possibilities such as load leveling, improved availability, and compensating work, to name just a few. This column starts with a brief introduction to Windows Communication Foundation queued calls and then presents an interesting problem-how to get results out of a queued call-and the solution via some cool Windows Communication Foundation programming techniques and a few helper classes.

Amazon SQS makes queuing messages across organizations over HTTP a snap with its Web service interface and Amazon-backed infrastructure. This article walks you through the process to get started using Amazon SQS to create and control queues and messages.

Web Service Software Factory is designed to help you build Web service solutions that follow known architecture and design patterns, as Aaron Skonnard explains here.

This article is a simple, step-by-step guide for those who have ideas and want to quickly implement them. We'll use code to demonstrate how easy it is to build an application on Amazon S3. We'll also highlight questions that you may ask before releasing an application.

To consume external Web services in Atlas, you build a server-based Web service proxy to the service. The good news is that you can leverage Visual Studio and Atlas features to handle most of the work.

Effective techniques are revealed to developers and testers on testing Web Services for reliability and robustness. These techniques demonstrate how a user can push the boundary of testing Web Services intelligently, without having access to the source code to a Web Service.

Passing large amounts of data through web services can become a huge bottle-neck in a WAN application architecture (i.e., server is on the web), and in any case, a real load on the network traffic. This is one solution for downsizing the network costs.
