By leveraging services in the cloud, businesses can host new applications and services in a cost effective manner. Existing systems can also leverage the cloud in its entirety or for specific aspects of the system to reduce infrastructure management costs and to support potential scale-out requirements as usage increases. Windows Azure offers many services from application hosting, storage, content delivery, messaging, caching and security. Pricing each of these services to estimate your costs requires some thoughtfulness around how you will use each service within your architecture, and some predictions about the number of users, payload traffic and number of transactions. How then can you estimate your costs, or price your own offering to customers when there are so many variables? Pricing is not a perfect science and each business will have its own level of tolerance for cost absorption vs. costs to be deferred to customers. In this session we will break down the pricing model of the cloud, look at ways to quantify your service using various architectural examples, and look at ways you can track usage, validate costs and ultimately collect your costs across the core Windows Azure features to gain perspective on what you need to charge your customers for those services, along with some ideas on how to project revenue.
