Web service mediation patterns for dynamic routing of multiple tenant requests using WebSphere DataPower SOA Appliance
Explore one of three IBM middleware based mediation patterns for rapid
enablement of multi-tenancy for existing Web services implementations. This first
pattern demo uses WebSphere DataPower Appliance.
In this demo, a scenario shows where multi-tenancy is enabled for a existing single tenant credit
check service by introducing a WebSphere DataPower Appliance based mediation pattern layer. This pattern layer uses a WebSphere DataPower Appliance Web service proxy and simple XSL routing policies to route service invocations from a tenant bank's user to endpoints dedicated to that tenant. The proxy also authenticates and authorizes users against policies configured in Tivoli Access Manager.

SOA governance framework and solution architecture
Service-Oriented Architecture (SOA) promises to deliver business agility by
aligning business and IT needs and goals. But without proper governance, an SOA
implementation is just a group of potentially unrelated services that doesn't
deliver anything of sustainable value. As part of an SOA initiative in your
enterprise, it's crucial to successfully initiate SOA governance to help guarantee
the success of an SOA implementation. This includes recognizing when to integrate
IBM WebSphere Service Registry and Repository into the SOA architecting process. In
this article, learn about SOA governance, and find out how WebSphere Service
Registry and Repository can help in your efforts. |

Mock Web services with Apache Synapse to develop and test Web services
Apache Synapse is a simple, lightweight, high-performance enterprise service
bus (ESB) released under the Apache License, Version 2.0 from the Apache Software
Foundation. Using Apache Synapse, you can filter, transform, route, manipulate, and
monitor SOAP, binary, XML, and plain text messages that pass through your
large-scale enterprise systems by HTTP, HTTPS, Java Message Service (JMS), Simple
Mail Transfer Protocol (SMTP), Post Office Protocol Version 3 (POP3), FTP, file
systems, and many other transport mediums. But for an individual developer, what's
the use of an ESB product in your day-to-day life? The simplicity of the
configuration, out-of-the-box feature set, extensible architecture, and the minimal
footprint makes it a versatile and powerful tool that you can use for a variety of
tasks. This article examines how you can use Apache Synapse to create mock Web
services. |

Develop and deploy multitenant 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. |

semantics must be propagated across these protocols so they
can seamlessly participate in the global transaction. This article walks you through the steps

Comment lines: Andre Tost: Visualizing SOA, from the first step to Second Life
Those of us involved in SOA projects are constantly looking to find appropriate ways to visualize aspects of the systems we are developing, from component maps and business models to patterns and flows, and even monitoring dashboards. But much of this information is static, and all of it is two-dimentional. New technologies present the possibility of dynamic and three-dimentional views that could enable us to not only observe a system in a virtual world, but also to interact with it so that our actions are applied to the real system.

IBM SOA Foundation product integration: Using WebSphere Transformation Extender with IBM Enterprise Service Bus products
The transformation to a service-oriented architecture (SOA) includes aspects that cover the entire lifecycle of a solution, from inception, to design and development, to its ultimate deployment and management. IBM published an SOA Reference Architecture that helps structure and position these aspects into a number of different components, and the IBM SOA Foundation includes a set of products that address specific components within the overall architecture. This article is the first of several that will discuss how products that are part of the IBM SOA Foundation can be used together. First up: how to add advanced transformation capabilities to IBM's set of Enterprise Service Bus (ESB) products: WebSphere Message Broker, WebSphere ESB, and WebSphere DataPower.

RESTful SOA using XML
Service Oriented Architecture usually implies heavyweight technology for large
enterprises. The advantages of the SOA architectural pattern also apply to smaller
environments. To follow SOA principles, you don't necessarily need all the overhead that
is useful in larger environments. You can use lightweight principles like REST to do so. This article describes how.

Build Web services with transport-level security using Rational
Application Developer V7, Part 2: Configure HTTP basic authentication
Part 1 of this tutorial series gave you step-by-step instructions for
building a Web service for a simple calculator application. You generated Web services and tested

Modernize legacy systems using an SOA approach
To remain competitive, your organization has to modernize its IT systems.
Modernized IT solutions must create new value from existing systems and provide
flexibility and easy interoperability among a broad set of technologies -- usually a
challenge with legacy applications. Service-Oriented Architecture (SOA), widely
adopted by organizations in recent years, offers a practical solution for evolving
and reusing existing assets. This article shows you a typical approach to
modernizing your legacy systems, including identifying the IT pieces that must be
augmented with new features, determining how the required augmentations are
performed, exposing each capability through a modern interface, and using the newly
exposed services to automate future business processes. |

Building a grid system using WS-Resource Transfer, Part 5: Using WS-RT for work distribution
In this five-part "Building a grid system using WS-Resource Transfer" series, we look at the use
of WS-Resource Transfer (WS-RT) in different areas of the grid environment --
from using it as a method for storing and recovering general information about
grid-to-grid monitoring and management, and security. We also examine how WS-RT can
be used for the distribution and division of work. In any grid, there is a huge
amount of metadata about the grid that needs
to be stored and distributed. Using WS-RT makes sharing the information, especially
the precise information required by different systems in the grid, significantly
easier. Here in Part 5, we look at using WS-RT for work distribution. |
