Business intelligence (BI) and service-oriented architecture (SOA) have conflicting principles and needs. SOA promotes hiding the data inside the services while BI needs that very data if we want to get meaningful predictions and alerts. This article will show you how you can combine SOA with EDA to solve the BI/SOA conflict and maybe even enhance your SOA.

Agile, Architecture and the 5am Production Problem
Can refactoring and unit testing really create robust “working software” that survives the real world? In this story adapted from his book Release It! Michael Nygard contends that "abstractions leak": we need to attend to architecture, even in Agile projects, to guard ourselves against the 5AM failures that occur when foundational abstractions misbehave.
