Introduction
Reliability—sometimes also called resiliency—is the ability of an application to avoid failure and recover from it quickly when it occurs. The degree of reliability your application will achieve is proportional to the amount of effort you put into the design up front, as well as the money you spend to operate it. Achieving a high degree of reliability for your application is not a trivial matter and entails significant cost and complexity. Therefore, before...
