Programowanie w chmurze

Cloud Computing (programowanie w chmurze) to kolejny ważny krok w rozwoju informatyki, na tyle znaczący, że jest utożsamiany z początkiem nowej ery, nazywanej erą chmury obliczeniowej, w skrócie chmury. Ponieważ jest to termin dość nowy, bywa często używany w wielu kontekstach, niekiedy do określenia różnych szczegółowych bytów. Często mówi się o chmurze nawet w kontekście systemu poczty Google Gmail lub usług Amazon Web Services czy wreszcie kompleksowych i w pełni funkcjonalnych rozwiązań "inteligentnych chmur" w rodzaju IBM Smart Business Cloud czy Windows Azure - chmury obliczeniowej w wydaniu firmy Microsoft.

Chmura to styl obliczeń, w którym dynamicznie skalowalne zasoby IT są dostarczane zewnętrznym użytkownikom w postaci usług na żądanie za pomocą technologii internetowych. Kluczowym elementem tej definicji jest dostarczanie usług "na żądanie". Chmura, oprócz dostępności usług we właściwym miejscu i czasie, zapewnia ekonomiczną efektywność rozwiązania, konsolidację zasobów, bezpieczeństwo informacji i wreszcie oszczędność energii.
