Achieving business agility with BPM and SOA together: Smart work in the smart enterprise
While BPM and SOA each have value on their own, this new white paper from IBM explains how they can be naturally synergistic. When implemented together, they can greatly increase business and IT agility, optimization, and alignment. BPM provides the business context, understanding, and metrics, while SOA provides a governed library of well-architected service and information building blocks. Both are needed in order to dynamically optimize investments, drive operational excellence, and manage business risk.

Exposing RESTful services using an Enterprise Service Bus
As REpresentational State Transfer (REST) is becoming more popular, more
non-RESTful service consumers and providers need to be adapted to make use of the REST invocation style. For such an adaptation, the Enterprise Service Bus can provide required mediation to expose non-RESTful services to be invoked RESTfully without the need to make changes to those services. This article shows how you can expose services RESTfully using IBM WebSphere Enterprise Service Bus, IBM WebSphere Message Broker and IBM WebSphere DataPower along with examples on how to test this work and sample consumers using different programming platforms.

Standards and Web services
Web services are a set of emerging standards that enable interoperable
integration between heterogeneous IT processes and systems. You can think of them as
a new breed of Web application that is self-contained and self-describing, and that
can provide functionality and interoperation ranging from the basic to the most
complicated business and scientific processes. In short, Web services hold the
promise for providing a common standard mechanism for interoperable integration
among disparate systems, and the key to their utility is their standardization. This
common mechanism for delivering a "service" makes them ideal for implementing a
Service-Oriented Architecture (SOA).

Problem Determination through Defensive Infrastructure Architecture: Part 1: Runtime deployments with queues and ESBs
The widely known "keep it simple strategy" (KISS) is a wise practice to follow
when building out an infrastructure. Application deployments, packaging and
placement requires considerable thought and effort to execute well. However,
sometimes what appears to be a simple implementation can hinder problem
determination leaving a production runtime unstable or, worse, unavailable. What is
simpler for one side of the IT development or operations staff makes troubleshooting
and root cause analysis that much harder because it is difficult to separate out
discrete events or the lack of valuable but missing data. This article looks at some real life examples where "more is actually less" when it comes to KISS.

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.
