"System performance is designed and built into a system. It does not just happen."
"The application has the biggest impact on scalability."
"In many cases, the cost of re-designing a system with the associated downtime costs in migrating to new implementations exceeds the costs of properly building the original system. The moral of the story is simple: design and implement with scalability in mind from the start."
"However, any performance increases achieved by adding hardware should be considered a short-term relief to an immediate problem."
"Poorly designed systems perform poorly no matter how much extra hardware is allocated" - моя любимая.
"In the most general terms, if the design looks correct, then it probably is."
"If the calls to the database are abstracted away from the application logic by many layers of software, then there is probably a bad software development method."
