Develop and Deploy Multi-Tenant Web-delivered Solutions using IBM middleware: Part 1: Challenges and architectural patterns
Web-delivered solutions that follow a Software as a Service (SaaS) delivery model -- where customers subscribe to software and access it from a service provider site rather than get licenses and have software installed on their premises -- can offer compelling business value for businesses of any size. Solution developers who develop new solutions or transform existing solutions and service providers who deploy these solutions are faced with several technical challenges. One example is multitenancy, where a single instance of the software, running on a service provider's premises, serves multiple organizations. This article series describes different patterns to address these challenges, often using Service-Oriented Architecture (SOA) techniques. Also learn how IBM software products can help you build and deploy scalable, configurable, and cost-effective multitenant Web-delivered solutions.

Comment lines: Scott Simmons: Don't let the greatest benefits of SOA elude you
Project-based SOA solutions typically result from a bottom-up, technical focus. These solutions provide an entry point for SOA and provide needed hands-on experience with SOA design and development tooling, but usually offer minimal benefits from an enterprise architecture standpoint. Organizations lacking an enterprise approach to SOA can still be successful, but they will find that the benefits of SOA will elude them.

Java theory and practice: The pseudo-typedef antipattern
The addition of generics to the Java language complicated the type system and increased the verbosity of many variable and method declarations.
