How build and deployment should shape software architectures

Build and deployment concerns can help us to avoid some architecture anti-patterns, and enable some useful system properties.

1. How build and deployment should shape software architectures Matthew Skelton CEng | thetrainline.com IASA UK Ignite 2, London | #iasaignite 10 September 2012
2. Systems engineering (robotics, control theory, sensors, neuroscience) Software development (finance, insurance, travel, pharma, media, medical imaging) now Build & Deployment at thetrainline.com @matthewpskelton
3. architecture = f (build & deploy) (for some systems)
4. “HERESY!”
8. RELIABLE REPEATABLE RAPID RECURRING
9. Web-based Frequently- changing Public-facing High-volume
10. ‘R-R-R-R’ BUILD AND DEPLOYMENT Helps to avoid the Ball of Mud
12. BUILDABLE Small pipelined builds on generic build machines Seconds, not minutes or hours Short feedback cycles (Dan Worthington-Bodart, @danielbodart - http://bit.ly/M85wsX)
13. TESTABLE Test (separation, harnesses, points) IDENTIFIABLE Meaningful versions, packages, defined dependencies, artefact management (think component boundaries)
14. DEPLOYABLE Rapid, scriptable, simple failure modes MONITORABLE Logging, metrics, transaction tracing CONFIGURABLE Inject settings – no ‘black boxes’ LIGHTWEIGHT Keep things small and easily comprehendible
15. INSTANTIABLE No snowflakes or singletons RECOVERABLE No nasty zombies after failures MTTR more important than MTBF* * for most kinds of F
17. RELIABLE REPEATABLE RAPID RECURRING
18. Lightweight, Testable, Monitorable, Configurable, Recoverable, Identifiable component architecture
19. LOAD BALANCING HIGH AVAILABILITY SCALING ELASTIC ARCHITECTURES RAPID RECOVERY
