A Journey of False Starts This is not the first time you’ve had your heart set on revolutionizing your information systems: One year, you rolled out a big Enterprise Application Integration (EAI) initiative, but it was too brittle and carried high maintenance costs. For a while you experimented with Web Services, but found that while they were easy to work with, they were largely insufficient to meet your broader needs due to a lack of architectural design guidelines. Out-sourcing, in-sourcing, up-sourcing, down-sourcing, and cross-sourcing just seemed to shuffle the work around and tended to result in the blame-game. You’ve bought every pill and tonic you could find (ESBs, network appliances, UDDI registries, load balancers, etc.), each with varying degrees of success. One crazy weekend you deployed a full-scale dynamic rules engine to fully automate decision log... (more)

Move over Reliability, Resilience has arrived

[This article was originally written as a guest post for Puppet Labs and published at their blog on January 9th, 2014.] If you haven’t yet noticed that prioritization of non-functional requirements (NFRs) is changing amongst your user base, you will soon. For decades, we have held to the same familiar set of NFRs. Every team had its own definition and particular spin on NFRs, but the usual suspects are accessibility, availability, extensibility, interoperability, maintainability, performance, reliability, scalability, security, and usability.

Which Came First, the SOA or the Data Model?

Recently I have been engaged in two Master Data Management (MDM) initiatives within the context of a larger Service Oriented Architecture (SOA) adoption plan. In both cases, the client found themselves at an impasse regarding how to resolve conflicts between the master data model and the data model required for one or more SOA artifacts (i.e. business process, service interface, etc.). Each client approached the problem from a different direction, but the conflict was essentially the same. Who wins and gets to run with their view of enterprise data? The MDM team or the SOA team? ... (more)

Big Data May Have Big Problems in 2013

Unless you’ve been hiding under a rock, you are aware of the hype around Big Data and Predictive Analytics.  The potential is mind-blowing, but organizations looking to pursue Big Data must be cautious and consider the enabling pieces that need to be in place in order to be successful.  Otherwise, irrational exuberance may well lead to a Big Investment in a Big Disappointment. Earlier this month, I was interviewed for the Cloud Computing Journal as a survey of IT pundits on the subject of Big Data Predictions for 2013.  While many were extolling the virtues of Big Data, I was th...
