The most critical component in capacity planning and performance engineering is the Workload Model, which defines the workflows, throughputs, and target performance your system must support at peak loads. As critical as it is, it can be difficult and particularly challenging to predict loads for new applications, features, or events. A typical approach starts with a wild-guess worst-case scenario—but overestimates waste time and money, and force you to engineer applications and infrastructure to support unrealistic loads. Low estimates can result in terrible customer experiences, lost...
