By Uwe Friedrichsen Slide 74 - a couple of resilient software design patterns Slides: http://de.slideshare.net/ufried/patterns-of-resilience In this slide deck, I first describe what resilience is, what it is about, why it is important and how it is different from traditional stability approaches. After that introductory part the main part is a “small” pattern language which is organized around isolation, the typical starting point of resilient software design. I used quotation marks for “small” as even this subset of a complete resilience pattern language still consists of around 20 patterns.

Sie fokussieren sich oft auf eine Nischengruppe und verzichten nicht nur auf überflüssige Features, sondern in einigen Fällen sogar auf die ganze Datenbankschicht. Bei kleinen bis mittleren Web-Projekten haben sie sicherlich das Potenzial, WordPress und Co. zu ersetzen. Und wer weiß – vielleicht feiern wir mit Kirby, Craft oder Koken in zehn Jahren eine neue Erfolgsgeschichte.
