Performance Testing in an Ephemeral Environment


#1

Awhile back I had an interesting problem to solve. I was involved with refactoring a cloud-based application that did intensive data analysis on very large data sets. The entire application —business logic, analysis algorithm and database — lived in a single virtual machine. Every time the analysis algorithm ran, it maxed out CPU capacity and brought the application to a grinding halt. Performance testing the application was easy: We spun up the app, invoked the analysis algorithm and watched performance degrade to failure. The good news is that we had nowhere to go but up.
