sklopovlje i programska podrška u datacentrima koji omogućuju takvu uslugu. (SaaS)
Cloud: Sklopovlje i programska podrška koji se nalaze u datacentru.
Neograničena skalabilnost
• Kapacitet dinamičkog skaliranja prema uporabi
Pay-per-use
• Uobičajeno se plaća samo ono što se koristi
Bez troškova uspostave
• Nema kapitalnih investicija, samo operativni troškovi
Isključena potreba upravljanja sustavima
• Miniimalno upravljanje sustavima od strane kupca

Javni ili privatni oblak?
ONPREMISE / HOSTED / CLOUD
• Povećanje gustoće transakcija i resursa
– dijeljena infrastruktura, elasticitet
• Povećanje apstrakcije i smanjenje granularnosti
– On demand servisi, dijeljena infrastruktura, elasticite
• Upravljanje učinkovitošću aplikacije
– Dinamička infrastruktura, elasticitet, pay as you go
• Smanjenje dijeljenja „stanja” i međuovisosti
– Elasticitet
• Povećanje paralelnih zadataka
– Elasticitet
