Fundamental SOA Concepts
This 48-page PowerPoint presented in pdf format includes ZapThink’s basic introduction to SOA, focusing on the ZapThink SOA Roadmap. This presentation is the first to present three versions of the Roadmap: one with implementation steps, one with project milestones, and one with SOA maturity levels. It was presented at the IPT 4th SOA Practitioners’ Conference in Zurich and Frankfurt in June, 2006.[hide -2]Download File[/hide][hide +1]Subscribe Today to Get Access![/hide]…

Grappling with SOA Change and Version Management
ZapThink frequently speaks of change, since change is the one consistent reality underlying the entire business world. Change, after all, focuses businesses on realizing the benefits of Service-Oriented Architecture (SOA), because the primary reason for embarking on a SOA project is to improve business agility while reducing IT costs in the face of today’s brittle, inflexible, and tightly coupled systems. However, let’s not let the perfume of the SOA rose intoxicate us too much, since implementing SOA itself introduces change every bit as significant as the forces of change that SOA is meant to address. SOA implementations must be built to change, or companies will never be able to realize the agility and cost savings benefits that SOA promises. In particular, a number of change and versioning issues arise when dealing with the sort of living SOA that companies so desire today. Versioning Service Contract Metadata The core…

RAX-J: Radically Improving the Processing of XML Applications
XML is rapidly becoming the protocol and format of choice for interactions among disparate systems and organizations connected via networks. More than a text-based, metadata format for data interoperability, XML is now the answer to solving many of the long-standing issues with application and data integration as well as providing a lingua franca for developers to create application programming interfaces (APIs) that arbitrary systems can interact with. Despite all the positive momentum that XML continues to garner in the enterprise, XML remains a highly inefficient and burdensome protocol to process. XML processing requires a dozen steps or more, including parsing, decryption, validation, and message transformation activities. This burdensome collection of tasks is increasingly bogging down systems with menial chores before they can even begin processing business logic. This paper aims to take the XML processing challenge one step further by suggesting that developers are the cause of many of…

SOA for Independent Software Vendors (ISVs)
As Enterprise Architecture, Service-Oriented Architecture (SOA) is particularly useful in large enterprises, and increasingly, to small and midsize businesses, as well. However, those are only one part of the IT ecosystem. What about those companies that are in the business of building and selling software products, so called independent software vendors (ISVs)? Generally speaking, ISVs create and sell software products that run on one or more IT platforms. ISVs might offer consulting services, but they typically aren’t consulting companies per se. Neither are they simply Value-Added Resellers (VARs) or Original Equipment Manufacturers (OEMs), who embed or customize someone else’s products. Rather, ISVs sell their own intellectual property as installable, configurable software. The largest software vendors are responsible for the enterprise applications that we run, the operating systems we use, and the infrastructure platforms on top of which we conduct business — think IBM, Microsoft, SAP, Oracle, HP, and CA.

Solving the Service Granularity Challenge
For us analysts that have been covering the markets around XML, Web Services, and Service Orientation it certainly is heartening to see that our audience of end users, vendors, and consulting firms are now asking some of the more complex and deeper questions around how to do architecture right. It seems that we’ve finally crossed the chasm and architects in particular now have a pretty good idea what SOA is and why they need it. Rather than trying to redefine what SOA is and what is means to the business, people are focusing on the more important issue of how to do SOA right. In that vein, some of our most recent conversations have centered on how to go about building the “right” Services. A key part of answering this question is making sure that we build Services at the right level of granularity. Granularity is a relative measure…

SOA for SMBs
Small and midsize businesses face quite different integration challenges than large enterprises. Internal integration needs are more straightforward than at larger firms, while business models are more likely to focus on business-to-business integration with suppliers and customers. Traditional approaches to B2B integration like EAI, however, are notoriously inflexible and expensive. Many such firms are leveraging Web Services to reduce the cost of older approaches to address their external integration needs. The simple addition of Web Services interfaces, however, typically remain as inflexible as the API approaches that came before. Only through the application of Service-Oriented Architecture can midsize firms build and leverage loosely coupled Web Services that are flexible enough to respond to ongoing change in the business environment.[hide -1]Download File[/hide][hide +0]Register to Access this Document[/hide]…

Service Orient or Be Doomed: ZapThink Analysts Announce Publication of their Latest Book!
Ever wonder why businesses are unable to keep up with today’s pace of change? Name your business goal–productivity, profitability, efficiency; today, they all depend on Information Technology (IT). IT is more important to business today than it ever was. While IT in the past has helped companies increasingly make their businesses more productive and efficient, today’s IT is simply getting in the way of change. It is increasingly becoming clear that the way that businesses utilize IT is increasingly making them less agile, less responsive to change, and less able to capitalize on new opportunities. Something has to be done to stop the problem of IT becoming the bottleneck of business. SERVICE ORIENT OR BE DOOMED! How Service Orientation will Change Your Business (Wiley, February 24, 2006;$39.95 cloth) is the first book aimed at regular businesspeople that helps business become more agile by offering technological, process, and cultural changes…
