Modernizing the Mainframe for SOA: Considerations for Transforming Mainframe Assets into Services

Dan Finerty

Dan Finerty

In order to realize the core business imperatives of increasing agility and efficiency SOA demands that organizations reconsider the value of legacy technologies and examine ways to extend and enhance that value rather than taking a "toss the baby out with the bathwater" approach to modernization. This article discusses how to transform and modernize the mainframe into an active, industry-standard participant of SOA implementations. It provides step-by-step guidelines to ensuring that the mainframe's strengths are leveraged, allowing it to become a full-fledged member of service-oriented solutions. Available technology approaches that enable the mainframe to both provide and consume Web services are also discussed...


SOA and Composite Applications

Robert Schneider

Composite applications (also known as "enterprise mashups") deliver immediate, cross-system interactive value to users while showcasing the value of your investment in a service-oriented architecture. Today's standards-based infrastructure and powerful development tools make these applications possible. Composite solution design is particularly compelling in an environment standardizing on SOA. This article explores the synergy between the concepts and principles associated with composite applications and the service-orientation design paradigm. Further aspects of composite design are discussed and explored, along with guidelines that address security, reliability, and performance considerations...


SOA Principles: An Introduction to the Service-Orientation Paradigm

Chris Farrell

The ability to effectively manage and monitor application performance is emerging as a new critical business imperative. With the mass adoption of SOA and the wide-spread deployment of enterprise service-oriented solutions, what steps must companies take to reduce application downtime? Traditional application performance management (APM) methods don't adequately address the constantly-changing nature of distributed environments. They simply don't take into account the layers of complexities that underlie multi-platform, multi-vendor, and even multi-company solutions. This article will examine the concept of "modeling" an application's architecture in support of its eventual performance management. It will also explore how automating the APM process for service-oriented applications can reduce the risk and effort associated with the management of application performance...
