Applications tie into revenue generation (e.g., selling products, serving ads, displaying visual content, etc.) or provide a service that's a part of your core business strategy. Optimize for those goals. Approach the problem from the point of view that it's acceptable for every other service/component to fail, as long as most critical business processes work. As a CEO of a large e-commerce company once said to me, "I don't care if my data center is on fire, as long as I'm still making money."
