saas - Normal web app Vs cloud based web app -


we hear cloud based computing lot these days.

i wanted understand basic difference between web app , 1 uses cloud based (saas model say) said cloud means hosting application @ common place users, instead of 1 per user. find confusing since normal web app same. difference ?

although many times saas might sound similar webhosting , different in following aspects :

  • saas application access sold using subscription
    model, customers paying ongoing fee use application.

- saas provider hosts application , data centrally—deploying patches , upgrades application transparently, , delivering access end users on internet through browser or smart-client application

  • and of course main difference being multitenancy the
    application layer , application different each tenant based on varying levels of tenancy

4 multitenant models cutting across 3 layers.
