Explosive growth; millions of users; global 24/7 usage -- it's a dream wished by many and a nightmare experienced by few. It's the Web-Scale, and it's redefining how we create and deliver software. If a run-of-the-mill enterprise application is like a Honda, then a Web-Scale application is like a Formula 1 car -- engineering and maintenance challenges included. One missed detail, and you could lose the race, or worse, hit the berm and end up as a tangled-mess of scrap metal. But unlike Formula 1, there are no pit stops or scheduled maintenance windows. Changes to Web-Scale applications must be error free and have no down-time... unless you want to face a mob of angry, demanding users somewhere in the world, and an even angrier mob of managers and investors. In this talk, we'll discuss various deployment strategies, scalable delivery, and how a few real-world Web-Scale organizations do it, from AllRecipes.com to Twitter, and even the monstrous Google.
