Embracing Concurrency At Scale

Posted by Justin Sheehy  on  Jun 23, 2010

Justin Sheehy explains why a paradigm shift is necessary when dealing with large concurrent distributed systems and what are some of their requirements: no global state is shared, ACID no longer works but rather BASE and CAP, getting rid of RPC and using protocols over APIs instead, prepare for failure, degradation, understanding the harvest-yield balance, and using measurement.

Hooking Stuff Together - Programming the Cloud

Posted by Gregor Hohpe  on  Jul 08, 2009 3

This talk describes the constraints of connected systems design and presents common design patterns to address some of the challenges developers will face as they spend more time connecting services and components instead of developing new ones. Along the way he asks: Is coupling really so bad? Why is REST popular? Do we need distributed transactions?

Unshackle Your Domain

Posted by Greg Young  on  Jun 24, 2009 12

This presentation, from QCon SF 08, analyzes real world projects where using explicit state transition models was made and the many interesting modeling/architectural possibilities that arose from the decision. Along the way, the IMIS system and its performance is linked to explicit state transition modeling.

Financial Transaction Exchange at

Transaction Management Strategies in Mission Critical Applications

Posted by Juergen Hoeller  on  Sep 11, 2007 6

A core part of Spring's middle tier support is the transaction management support. This session presents several interesting "mission critical" cases and shows you how to properly handle them using transactions driven by Spring 2. You'll learn the ins-and-out of the "dark art" that is transaction management within a high-volume mission-critical JEE application.
