Creating Contract and Policy Metadata
One of the first questions that archtiects and developers are posed with when building an SOA is exactly how to build a “Service”. Companies building loosely-coupled Services know that contracts and policies, built in metadata, are key to making SOA work. So, what exactly goes into Service contracts and policies, and what specifications are currently available to meet Service contract needs? This 24 slide presentation outlines some of the key issues in creating and implementing Service contracts as well as the steps companies should take to create them.

So, Where are the Architects?
If you’ve been paying attention, one of the things that the movement to the sort of agile IT that Service-oriented architecture (SOA) enables is a new set of roles and responsibilities in the organization. We often blame today’s IT departments and their technology purchases for being responsible for the integration rats’ nests that are the cause of today’s inflexibility, and we frequently chastise the business folks for making expedient, short-sighted decisions that only make the problem worse. So, is there a way out of this puzzle? Is there anyone in the organization that can hope to get the vision of Service Orientation right, or is this all a hopeless struggle? Fortunately, there is hope, and it comes in the form of enterprise architecture. As we’ve frequently discussed, the most critical part of making SOA work is doing architecture well. So, if there’s a need for architecture, then it figures…

Using Industry Information Models to Guide Service Definition
One of the greatest challenges that companies face as they implement SOA is deciding which Services to build. Companies can take advantage of either general-purpose or industry-specific information models to act as a starting point for their Service definition and business vocabulary efforts as part of an SOA initiative. However, they must resolve the issues of excessively broad and ambiguous models in order to specify Services adequately.[hide -1]Download File[/hide][hide +0]Register to Access this Document[/hide]…

The SOA Pilot Pitfall
All new technology projects have to start somewhere, and pilot projects are a great way to try out new approaches as challenging and complex as Service-oriented architecture (SOA). Over the course of the past five years, ZapThink has interacted with countless companies who are planning or executing SOA pilots, many of which are well-conceived, competently executed, and reasonably successful. However, we have also seen a foreboding pattern of ill-conceived SOA pilots forming in information technology (IT) shops throughout the world, and these problem pilots all seem to succumb to the same pitfall. It is time, therefore, to take a closer look at what makes for a good SOA pilot, and how to learn from the mistakes of others and avoid the SOA pitfall. Defining the SOA Pilot A pilot project is a trial project that seeks to evaluate some new technology or approach and determine whether a company…

Industry Luminaries to Debate Implementation for Service-Oriented Architecture on Live Webcast
WALTHAM, Mass.–(BUSINESS WIRE)–April 25, 2005–Companies are grappling with the best way to implement the rapidly growing Service-Oriented Architecture (SOA) approach to distributed computing, including Enterprise Service Bus (ESB), SOA Fabric, and other means to implement SOA. To address these issues, ZapThink is hosting the industry’s key luminaries on this topic – Gordon Van Huizen from Sonic Software and Frank Martinez from Blue Titan – on its May 4, 2005 ZapForum Webcast entitled “The Great Debate: ESBs, Fabrics, or Something else?” “There’s way too much inconsistency in how companies are defining and tackling the various methods for implementing SOA,” said Ronald Schmelzer, senior analyst with ZapThink, LLC. “We hope to settle some of the issues around ESBs, SOA Fabrics, and other modes of implementing SOA once and for all on our May ZapForum Webcast.” Run like a call-in radio talk show, the ZapForum Webcast starts with thought-provoking content lead…

Who's in Charge of your SOA?
As forward-looking enterprises move beyond the Service-Oriented Architecture (SOA) pilot stage and plan their cross-departmental SOA initiatives, they quickly come to the realization that the technology challenges they face are actually the easy part of their SOA rollout. Far more challenging are the organizational and management issues they must overcome to successfully meet their business goals for the initiative. Of these, the critical management issue (and here we mean management by humans, not systems management) is that of control. Who is in charge of defining, managing, and running the shared Services the SOA offers? How must a company organize itself to manage the dynamic business processes that people across the organization can now create by composing Services and other processes? And of course, how should a company pay for the whole mess — Services, processes, and the architecture itself? The management and control issues that SOA introduce result from…

Solving the Very Large Messaging Problem in the Enterprise
Companies are increasingly seeking to tie together their disparate enterprise using the promising, but emerging technologies of XML, Web Services, and Service-Oriented Architectures. These approaches promise significant business agility in the face of IT heterogeneity. However, these benefits come at a price: performance and efficiency. As the network traffic increases due to the increasing size and volume of messages, both XML and non-XML based, existing corporate IT infrastructure will be taxed to its limit. General-purpose application servers, network equipment, and messaging infrastructure will be increasingly devoted to simple message parsing, handling, and routing functions, while precious few resources will be left to execute the core business logic so important to companies. Research shows that the quantity and size of these metadata-laden messages won’t be decreasing soon. Developers and specifications bodies continue to tax messaging systems with additional layers of headers and metadata meant to abstract underlying infrastructure. Increasingly large…
