Software performance guru Martin Thompson (@mjpt777) gave an illuminating talk on event-sourced architectures, and why event-driven, state-machine designs are the way forward for complex, multi-path software systems (“Event Sourced Architectures and what we have forgotten about High-Availability”, [slides: 700KB PDF]).

Jon Allspaw (@allspaw) from Etsy talked about the role that Anomaly Detection, Fault Tolerance and Anticipation play in producing highly scalable software systems (Fault tolerance, anomaly detection, and anticipation patterns, slides [PDF, 5MB]).
As head of technical operations at Etsy, whose web traffic is pretty substantial, Jon focused on resilience in software systems: what it is, and how to achieve it.

Stefan Tilkov (@stilkov) from innoQ gave an excellent talk on the importance of a “system-of-systems approach” to software architecture (Breaking the Monolith, slides [PDF, 1MB]).
In essence, he argued for a distinction between micro-architecture (the design of the individual [sub]system) and macro architecture (the design of interacting systems).

I’ve just returned from UK Scale Camp 2010 (@scalecampuk), organised by The Guardian (and the indefatigable Michael Brunton-Spall, ). Here are some notes:
I liked the “unconference” format (no formal programme; attendees vote for their favourite sessions in advance), and ended up in four of the many sessions:

Subject: You are invited to ScaleCamp 2010 – 10th December at the Guardian offices, London
Hey,
We are so pleased to be able to invite you to Scale Camp 2010 on the 10th December at the Guardian Offices here in London.
I’m looking forward to some great conversations and debate, particularly around DevOps and how that can contribute to scaling a software platform.
