The Forgotten Art of Performance Modeling

Performance modeling is needed today more than ever– it is time to revive it! 

Performance modeling significantly increases the value of performance testing. First, it is one more way to validate tests correctness and help to identify problems with the system. Second, it allows answering questions about sizing and capacity of the system. Performance modeling is needed today more than ever – as we embrace continuous performance testing and full-scale tests are not always feasible. How the change in that service performance will impact overall performance of the system? It is rather paradoxical that once popular topic of performance modeling became practically forgotten – it is time to revive it!
