Futtató környezetek szerepe egy szoftver életében

Környezetek

  • local - Fícsör kifejlesztése a saját gépen, amíg nem látszik a hiba
  • CI - Véleményt mondanak: minőségbiztosító eszközök, tesztek ✔ ❌, kollégák
  • staging - Bemutatjuk a hozzá nem értő ügyfélnek, illetve kipróbáljuk egy prod-hoz közeli környezetben
  • production - Oda adjuk a felhasználóknak
