Looking at the evolution of service composition, from SOA to cognitive services
Today, developers can create a wide variety of service compositions with a new breed of cognitive computing services. There are endless possibilities for creating service compositions, but that wasn't always the case back in the early days of service-oriented architecture (SOA) services. In this article, I review the history of service composition development and show how much it has evolved.

Big data in the cloud
Big data is an inherent feature of the cloud and provides unprecedented opportunities to use both traditional, structured database information and business analytics with social networking, sensor network data, and far less structured multimedia. Big data applications require a data-centric compute architecture, and many solutions include cloud-based APIs to interface with advanced columnar searches, machine learning algorithms, and advanced analytics such as computer vision, video analytics, and visualization tools. This article examines the use of the R language and similar tools for big data analysis and methods to scale big data services in the cloud. It provides an in-depth look at digital photo management as a simple big data service that employs key elements of search, analytics, and machine learning applied to unstructured data.

BPM Voices: Insight at the edge
In the world of mobile, cloud and APIs, how do you assert control at the edge of the enterprise, the boundary between the unpredictable external environment and the internal managed systems? And, perhaps even more importantly, how do you gain insight into customer behavior and preferences so that you can advance the customer relationship with every action you take? Resolving such questions is dependent on "insight at the edge" - the idea that by applying service-oriented principles to interactions between external systems of engagement and internal systems of record, you not only protect against undesired external influences, but can tap into the stream of consciousness that already flows through the business.

Using a combined SOA and TOGAF environment for increased productivity: Part 1: Introduction to the TOGAF Enterprise Continuum
Service-oriented architecture (SOA) can transform organizational silos into functional groups, thereby measurably increasing productivity. At present, both the Open Group Architecture Framework (TOGAF) and SOA are unapproachable and poorly understood. To succeed, a technology must at minimum offer two things; a reference topology (the defining structure) and a reference implementation flow (the defining sequence). These artifacts must always be at hand before, during, and after a project, because they offer a primary point of reference for planning, design, implementation, maintenance, and optimization methods. Part 1 and Part 2 of this three-part series attempt to recreate the noted structures for TOGAF and SOA, respectively. Part 3 follows up with an agile process that projects both frameworks against the same wall and offers methods to exploit the unique features that TOGAF and SOA have to offer.

Availability and Response Time Management in SOA environment with Tivoli Composite Application Manager for Transactions: A case study
As Service Oriented Architecture (SOA) is becoming increasingly important in software integration, an application built on SOA infrastructure is not standalone, instead, it depends on other applications. While some of these depended applications are inside the enterprise, some others are external applications provided by third-party providers. The complexity of the system, as a result, increases the difficulty to quickly sense and isolate application’s availability and response time problem. This article analyzes a typical application availability and response time management case in SOA environment, and presents a solution based on ITCAM for Transactions 7.1.

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.

Exploring the Enterprise Service Bus: Part 4: Federated connectivity in the enterprise
Driven by increasingly sophisticated business needs, service-oriented architectures have become more widespread, more mature and more sophisticated. A key driver of this growing sophistication is the need for multiple business units to cooperate and contribute to the overall business of the enterprise. From a business perspective, the result is generally called a federation or a federated enterprise. From an IT perspective, the enabler of a federated enterprise is often called a federated ESB, reflecting the role the ESB plays in providing service connectivity in SOA. But the ESB is just one part of an infrastructure that provides service connectivity in SOA, so it is more appropriate to discuss federated connectivity. This article describes the principles of federated connectivity and suggests an approach for creating efficient and effective federated topologies in SOA.

IBM SOA Foundation product integration: A complete ESB Gateway solution featuring WebSphere DataPower, Tivoli Access Manager, and WebSphere Service Registry and Repository
Leveraging the concept of a service-oriented architecture usually brings with it the ability to connect an increasing number of systems within an enterprise -- but also across enterprises. While enabling a higher degree of automation and reduced processing time, this also leads to growing concern about managing and securing the underlying connections between heterogeneous IT systems. This article describes how to address these concerns by implementing an ESB gateway using three of the products within the IBM SOA Foundation platform, beginning with integrating a IBM WebSphere DataPower SOA Appliance with IBM Tivoli Access Manager for security, and then adding IBM WebSphere Service Registry and Repository for endpoint address management.
