Reinventing Performance Testing: New Architectures

Alex Podelko

Auto-scaling is often presented as a panacea for performance problems, but, even if it is properly implemented (which is, of course, better to be tested), it just assigns a price tag for performance. As already mentioned, performance testing is rather a performance engineering process (with tuning, optimization, troubleshooting and fixing multi-user issues) eventually bringing the system to the proper state rather than just testing.
