ESB Pattern: What Is the ESB?

Thu, 10 Sep 2009 12:00:00 EDT

ESB products emerged around 2002 from message-oriented middleware (MOM). Faced with market domination by IBM, MOM vendors were the first to jumpstart the ESB concept with the aim of developing a unique selling proposition. They added Web service and EAI capabilities on top of existing message broker capabilities, and with analyst support coined the term ESB. ESB was positioned as a low-cost alternative to EAI and panacea for all integration needs – tell-tale signs of hype.

SOA Performance: Monitoring Bottlenecks in an Ultra-Heterogeneous Environment

Wed, 02 May 2007 13:00:00 EDT

To state the obvious: with mission-critical applications, your mission will fail around the same time your applications do. This truism is of immediate concern to .NET developers involved with Service Oriented Architectures (SOA), the loosely coupled software services that now support all kinds of business processes, including supply chains and customer-facing online applications. Failures or even brief slowdowns can take immense tolls because, well, the company's mission itself is affected.

SOA Transformation and Leveraging Open Source Principles

Fri, 05 May 2006 15:00:00 EDT

As numerous organizations are planning to embark on their first endeavors in service-oriented architecture (SOA), it is important to recognize that the necessary organizational transformation has as much to do with cultural transformation, as it has to do with open, Internet standards-based design. In fact, the very nature of how business and IT view each other's role and how the enterprise views its relationships with its marketplace partners and customers is being altered. Such cultural change has never come easily and represents a significant organizational dilemma.

Leveraging SOA to Web-Enable Back-End Applications

Mon, 20 Mar 2006 12:30:00 EST

Most organizations today have internal applications that span across different systems, networks, and technologies. These applications would provide more value to customers if only the data that they manage were exposed. In the past, this was often difficult due to the inability of systems to communicate with one other. However with Web service standards in place for several years now, services are finally gaining acceptance throughout the industry. Consequently, service-oriented architectures (SOAs) have finally come to fruition as companies start to rethink how they build enterprise applications.

An Architect's Guide to DSLs

Sun, 01 Jan 2006 17:00:00 EST

You are an architect on your company's new flagship application. The app encompasses several business and technical domains that are, in your opinion, well suited to domain-specific languages (DSL). In years past, you would have turned to XML as the solution for all your DSL needs. With or without schemas, you would specify configuration files and scripts in files foul with angle brackets. Thankfully, for the discerning .NET architect, DSL implementation options are now plentiful.

Populating Word Documents on the Server with Microsoft .NET

Thu, 29 Dec 2005 16:30:00 EST

Consider the following portion of an all-too-common server scenario. An authenticated user, perhaps a salesperson, requests a Word document from a server. The document is an expense report, and the server is an ASP, ASP.NET, or SharePoint Server. The server code looks up some information about the user from a database, Active Directory, or Web service. For example, perhaps the server has a list of recent corporate credit card activity that it will prepopulate into the expense list. The server starts up Word but keeps it 'invisible' because there is no interactive user on the server. It then uses the Word object model to insert the data into a table, saves the result, and serves up the resulting file to the user.

Microsoft CRM Mobile

Mon, 04 Oct 2004 00:00:00 EDT

Mobile devices, such as the Microsoft Windows CE-based PocketPC, have grown significantly in popularity over the last several years. In the car, on a plane, or out in the middle of nowhere, applications on the device can operate without a connection to any other computers, the Internet, or an intranet. Devices can then partner with a desktop system either via modem or network card, or simply by placing the mobile device in a cradle.

Raising the Bar

Thu, 11 Mar 2004 00:00:00 EST

Today's enterprise applications demand high levels of reliability, scalability, availability, and interoperability. These demands have fueled the growth of complex service-oriented architectures (SOA) built on industry standards such as Web services and XML-based messages. The added complexity of these types of applications has increased the requirement for powerful tools and platforms.
