I suppose it depends what type of code you’re developing but in general I’d expect a dev environment and unit tests, then a test environment and integration tests, a staging environment and UAT (or UAT in Test) and then production. Test or staging would usually have a copy of old prod data. It sounds as though you can’t predict the prod traffic though. Is there no sample traffic or even stats on types and volume of traffic over a period of time you can take to then feed to your test environment?
