Logical Architectural Diagramming Guidelines - UML 2.0 Style Guide

October 2008  These Architecture Diagramming Guidelines are intended to facilitate the communication of technology architecture. This can either be as a part of an Enterprise Architecture Governance process or simply in the flow of information from business requirements to systems architecture to technical design to implementation to operation.

They say "a picture is worth a thousand words" and where technology architecture is concerned, the old adage is pretty much true. As opposed to inventing something brand new, these Guidelines start with an existing, fairly widely used diagramming language called the UML (Unified Modeling Language).

Visio Shapes (UML 2.0) for Logical Architectural Diagramming

October 2008  The Visio shapes and stereotypes available from this site have been specifically developed to support the iankoenig.com Architecture Diagramming style. This style is an extension of (and fully compatible with) the "UML 2.0 specification" from the OMG. the UML (Unified Modeling Language) is a widely used specification for technical diagrams.

Architecture Principles

September 2008  Architecture Principles lay the foundation of an Enterprise Architecture. They are in essence the mission statements for the architecture. Architecture Policies derive from Principles and make them concrete and measurable. While no two Enterprises will have the same Enterprise architecture (unless they are in precisely the same business and address it in precisely the same way, there are many common elements where Architecture Principles are concerned.

The reference document attempts to present a " Starter for 10" without being overly prescriptive for defining a core set of Architecture Principles upon which to build.

Content Distribution in an Event-Oriented World

September 2008  This Presentation was given at the 4th EPTS conference in Stamford, CT held on 17-19 September 2008

It attempts to draw parallels between the application space where CEP fraeworks are prevalent (e.g. algorithmic trading in financial services) and other tiers of the content distribution stack. There is a common architectural pattern which applies to content distribution (and processing), that spans market data, textual data such as news, structured databases and even media (such as music). This lays some of the ground-work for and event-oriented SOA.

Caveat: It gets a bit abstract at times

Information Architecture and Taxonomic Classification

August 2008 This Presentation is a very high level introduction to the concepts behind Information Architecture, which is a systems agnostic view of Content, focusing on the Business Entities that link content sets together, Relationships used to navigate between Entities, Symbols / Identifiers used as Monikers and other subject based classifiers that are used to find, organize and contextually navigate content.

An Entity Model for Financial Services is included.

Service Oriented Architecture and Governance - 10 "Golden Rules"�

August 2008 This Presentation is an update from the original given as a webinar to The SOA Forum in March 2008.

It describes 10 "Golden Rules" for implementing a Service Oriented Architecture, so that an organization can leverage the cost benefilits and improved agility offered by shared technology services, while avoiding the most common pitfalls.

The bottom line -- SOA needs Governance!

Event Processing as a core capability of your content distribution fabric

18-20 September 2007 This Presentation was given at the 3rd EPTS meeting (Event Processing Technical Society) and at the Gartner symposium on Complex Event Processing from 19-21 September 2007. The presentation I gave at these meetings was when I was chief architect of Thomson Financial and as such the information, while not confidential is copyright Thomson Financial (now Thomson Reuters)

It positioned the Architecture Framework / Model for Complex Event Processing, using News as an �??interesting�?� Event-based content stream for algorithmic trading application - a key CEP application use case, including mechanisms for marking up news so that it is process-able by algorithms and for distributing it in an ultra-low latency manner
