Services that exist as independent concepts at design time are implemented as independent execution entities at runtime. Assuming that the conceptual system structure is equally useful during execution is a naive and potentially dangerous mistake. Instead, applying high-performance transaction system design criteria that optimize for runtime properties like performance, throughput, and resiliency should be paramount
