What is the Autoscaling Application Block? The Autoscaling Application Block (“WASABi”) is a part of the Enterprise Library Integration Pack for Windows Azure. The application block allows you to define how your Windows Azure Application can automatically handle changes in the load levels that it might experience over time. It helps you minimize your operational costs, while still providing excellent performance and availability to your users. It also helps to reduce the number of manual tasks that your operators must perform.

25 26 ch a pter thr ee Tailspin’s Goals and Concerns Resource elasticity and geo-distribution are key properties of the Windows Azure platform. Tailspin faces several challenges with the current version of the Surveys application. The initial development was done quickly in order to be early to market. This resulted in some compromises during the development process whereby some features were sacrificed, and the design process was tailored to meet tight deadlines, not to optimize maintainability and extensibility.

3. The third constraint rule is active every Friday (in the diagram, 12 August is a Friday, and labels C and D show when this rule became active and inactive). It sets the maximum and minimum number of instances for worker role A to three. It has a lower rank than the second rule, so between 8:00 AM and 10:00 AM on Fridays, the second rule overrides this rule; in the diagram, label E shows when this happened. Figure 3 shows the effect of using multiple constraint rules with different maximum and minimum values, but without any reactive rules.
