SOA antipatterns
Service-Oriented Architecture (SOA) is the de-facto architectural approach
for many IT initiatives. It is therefore important to understand the
circumstances where this paradigm breaks, as this can significantly impact
the delivery of IT programs. This article highlights two SOA antipatterns that
define problems that can occur in the execution of SOA deliveries. A
simple frame of reference for SOA is first introduced in the form of a layered
reference architecture. The reference architecture is then used to illustrate the
underlying reasons for the occurrence of the antipatterns. For each antipattern a description is provided that highlights the root causes of the problem and the approaches to re-factoring the solution, hence facilitating successful delivery. |

IBM U2 and Service Oriented Architecture (SOA)
Service oriented architecture is an application framework that takes everyday
business applications and breaks them down into individual business functions and processes, called services. SOA lets you build, deploy, and integrate these services independent of applications and the computing platforms on which they run, making business processes more flexible. In this article, learn how IBM UniData and UniVerse (U2) technology relates to SOA.

SOA Governance – How Best To Embrace it, Part 1: Introduction to Enterprise, IT and SOA governance
With immense projected growth, the Government must modernize its IT systems. Air traffic will double or even triple in the next twenty years, the number of retirees will double throughout the States, infrastructure will boom, the population will skyrocket, and under such pressures, the legacy systems will surely collapse, and if no action is taken, problems will abound.
Some government agencies have considered Service Oriented Architecture (SOA) as the most effective means to address this dire issue. Moving to SOA, however, entails substantial challenges. To this end, one of the government agencies requested IBM to collaborate with other partners of the agency and produce a whitepaper that addresses these challenges. This article expounds such information beyond this agency to industries across the board. |

Connecting to the cloud, Part 2: Realize the hybrid cloud model
This is Part 2 of a three-part series on connecting to the cloud. To determine the best solution for creating a hybrid cloud application, Part 1 examined some of the offerings from the major cloud platform vendors. In this article, Part 2 of the series, you will implement the hybrid cloud application, which combines local application components with cloud computing. The application makes use of a JMS queue locally as well as an SQS queue in the cloud, combining the two in a single hybrid application. |

Integrating Rational Software Architect with Rational Data Architect
Model-driven software development generally starts with either application
modeling or data modeling. Application modeling and data modeling, however, are closely
related to, and complement, one another. IBM has recognized the importance of
integrating application modeling with data modeling in model-driven software
development, and has developed the Unified Modeling Language (UML)-to-Logical Data
Model (LDM) and the LDM-to-UML transformations. These transformations integrate
application modeling using Rational Software Architect (RSA) and data modeling using
Rational Data Architect (RDA). This article provides a quick overview of RSA and RDA,
outlines the high-level steps in three RSA-RDA integration scenarios, and discusses the
UML-to-LDM and the LDM-to-UML transformations and the UML Logical Data Model Profile. [2009 Apr 17: Added note about Rational Data Architect changing product

Bracing Techniques when Common Information Model Meets the Message Layer in a
Service Oriented Architecture (SOA)
When leveraging the common information model (CIM) standard for middleware environments, creation of service components requires slicing and adapting the appropriate entities within the CIM. While slicing is normally driven by the business process, adaptation needs to be performed using a special technique termed as the “bracing technique”. In this article we will explore the bracing technique in detail; which in turn will enable service designers to create service interfaces that are highly flexible and easily consumable. |

Securing CICS Web Services
Securing access to information is important to any business, especially for business-critical systems that manage sensitive data, as is often the case for systems based on IBM CICS. Security becomes even more critical during SOA implementations, due to loose coupling of services and applications, and their possible operations across trust boundaries. |

Proactive WebSphere Enterprise Service Bus (WESB) Mediation: Timing a Mediation Module
This tutorial takes you through developing a WebSphere Enterprise Service Bus

to time and fetch the updates, based on a given time interval. This is a common
requirement, to poll systems, which cannot proactively post the updates occuring within them, to the other subscriber systems. This is achieved by a combination of a startup bean, scheduler, messaging task and a WESB mediation module. |

The operational context diagram
For many years, application architects and analysts have used the system
context diagram (SCD) as a powerful tool to share the high-level view of
a system. The SCD provides only a functional
view of the system, a view that later leads to the use case model. To
completely specify the system under development, non-functional requirements
must be taken into account. NFRs create another view of the system
context: the operational context diagram, which then segues to
the operational model. In this article, learn about a technique to complement
the SCD with a non-functional oriented operational context diagram.

Cloud computing with Linux
Cloud computing and storage convert physical resources (like processors and
storage) into scalable and shareable resources over the Internet (computing and storage
"as a service"). Although not a new concept, virtualization makes this much more scalable
and efficient through the sharing of physical systems through server virtualization. Cloud
computing gives users access to massive computing and storage resources without their
having to know where those resources are or how they're configured. As you might expect,
Linux plays a huge role. Discover cloud computing, and learn why there's a penguin behind
that silver lining. [And see the new Resource links to the latest developerWorks content on cloud computing. -Ed] |

Making content searchable anywhere using IBM WebSphere Portal's publishing Seedlist Framework
If you are developing an enterprise document-management application that serves as a platform to generate, manage, and publish content, you might wonder, "How can I make all the content available to end users in an effective and usable manner?" The answer is to enable users to search the content of the entire product. This white paper describes how you can make your published enterprise application content available for crawling by IBM search engines such as IBM WebSphere Portal Search Engine and IBM Omnifind Enterprise Edition 8.5. Learn how to achieve this functionality by using Content Provider Framework, also known as Seedlist Framework, and more specifically by implementing a simple set of APIs that returns the publishing content while handling critical aspects of security, rich metadata, and effective updates.

Learn how and when to grow clustered topologies that use IBM WebSphere Process
Server and WebSphere Enterprise Service Bus. When new BPM and ESB applications are
deployed, you may need to expand the initial topology to take advantage of increased IT
resources (such as memory) or to isolate applications. This article describes a standard
"golden topology" widely used in production deployments, and then examines how to grow
the topology from within the cluster, and by adding new clusters. It describes good and
bad design patterns, what to consider, and the costs and limitations of each approach.
The article also describes how to plan for Service Integration Bus connectivity and desired
messaging engine behavior. |
