The Annotated Next Generation SOA Business Case – Part I

Philip Wik

SOA not only optimizes systems. It also optimizes organizations. Much of SOA's successes are due to what comes before and around that architecture. This article presents some of that theory behind the business case in our Next Generation SOA book. The most recent book in the Prentice-Hall Service Technology series was Next Generation SOA: A Concise Introduction to Service Technology & Service-Orientation. The business case in chapter seven tells the story of a fictional company's transformation. Our goal was to show service-oriented architecture principles that the Rent Your Legacy Car Company (RYLC) used to make it more profitable in a highly scaled, non-trivial context. It's also a meditation on leadership and shows the tension between architectural abstractions and the slime of its real-world realization. Just as programs abend, corporations abend. The former is recoverable. The latter is a devastation, leaving in its wake incalculable wreckage. The corrective comes down to this proposition: If capitalism is the hope of the world, then SOA is the hope of capitalism. We need only to look at our stock portfolio to assess the extravagance of that claim. Drifting or plummeting stock prices tell us all that we need to know. These companies struggle to find their footing in the face of global competition. In our example, a mid-range corporation is trending towards oblivion. SOA is the solution. It solves the problem in two ways. First, it requires that the company makes structural changes to make SOA work. Secondly, SOA builds a platform to deliver services to meet changing markeplace demands. The purpose of our book and this paper is to make this point. Since Harvard University invented the case more than a century ago, strategists and students have used it as a tool for promoting holistic, multidimensional business thinking. It "creates the context in which leaders are formed: real-life...


The SOA Myth Busters Present: "SOA & Information Security"

So, do you like working with and around SOA? That's great because so do we, and we've been doing it every single day since a long time ago. As SOA professionals, we've seen the concept grow, change and mature, bringing up new dimensions and technology with it. We're Arturo Viveros and Rolando Carrasco, the SOA Myth Busters from Mexico, and through this series of articles, we will try and put to the test a number of questions, myths and urban legends regarding both Service Orientation & SOA Architectures in search of finding out which myths are true and which are not. We would like to give a special thanks to our collaborator and friend Tabata Jessica Pérez. Without her hard work, contributions and insight, this article wouldn't have been possible. In this installment, we will discuss one of the most neglected/overlooked themes when implementing SOA Architecture, and that is information security. Everyone understands to some point that in the digital era, securing our data, information systems, and communications and so on is of the utmost importance. It is also very clear that these kinds of items can be very easily compromised by a number of threats and vulnerabilities. After all, who hasn't heard in the news or elsewhere about cyber-attacks, identity theft, wiretapping, hacking, etc.? But what does this all have to do with SOA Architecture? Taken from our experience collaborating in a vast number of SOA projects, here are a number of statements (or should we say misstatements?) we have commonly bumped into regarding SOA & Information Security: Security is not a priority when designing / implementing an SOA Architecture. Security requirements can be kicked forward until the end of projects and dealt with once the services are in production. Including security considerations in the service's design, will only hinder...

To achieve the Global Village Service (GVS) in form of a services foundation, web developers confront with information and services integration in the software development projects. Beside, unifying most of services from these types of projects could be realized for the global village with the headache of the upcoming techniques; particularly cloud computing, along with coming patterns, like globalization. Hence, developers require certain basis architectures to enhance the development of the electronic services structure according to an extensive method. GVS is often referenced as the baseline of any type of software service engineering activities related to the software services and globalization, along with the cloud computing aspects. Precise prediction of service development effort is a popular problem both in commerce and also for academia. The term effort is a significant and valuable parameter in development process and service management. The suitable calculation of effort assists the project managers to assign the sources well and also handle price and duration to ensure the project will be done in the decided budget and time. Nevertheless, there can be very few GVS metrics built to assess difficulty, effort estimates and status of GVS methods. This article consequently suggests a GVS metrics framework that has both service-level and GVS-wide metrics to determine effort of a GVS approach. The global village is a phrase elaborated with Marshall McLuhan in 1962. McLuhan explains the way the entire world may be developed into a village by electrical technologies. Nowadays, the global village is usually employed as a metaphor to explain the world wide web and internet, while the expression 'Global Village' is popularized as residents of the globe, countries in the world, along with the world compared with a small village. In addition, computer software...
