Is gnách go ndéantar bogearraí a fhúscadh trí ilimpeallachtaí — cosúil le forbairt, stáisiúnú, agus táirgeadh — agus feidhmíonn gach ceann acu críche ar leith ar an mbealach ó chód go dtí úsáideoirí beo. Má bhíonn cód á thoghlacadh trí impeallachtaí, is féidir fadhbanna a ghabháil sula sroichidh siad fíor-úsáideoirí.
Na timpeallachtaí tipiciúla
DEVELOPMENT (dev) → where developers build and test (local or a shared dev environment);
unstable, frequent changes, experimentation
STAGING (test/QA/pre-prod) → a PRODUCTION-LIKE environment for final testing:
→ mirrors production (same config/infrastructure as closely as possible)
→ run integration/E2E tests, QA, UAT before releasing
→ catch issues in a safe, prod-like setting BEFORE real users see them
PRODUCTION (prod) → the LIVE environment serving real users:
→ stability is critical; changes are careful and monitored
