SaaS vs IaaS vs PaaS
An Entrepreneur Must Consider While Choosing a Suitable Cloud Delivery Model
SaaS vs IaaS vs PaaSEveryone knows that the cloud is a very broad concept and before
choosing a cloud service delivery model for your application or infrastructure deployment,
it’s important for an entrepreneur to look out the fundamental difference between the cloud
services available. There are three models of cloud service available: Software as a Service (SaaS),
Platform as a Service (PaaS), and Infrastructure as a Service (IaaS) and depending on the
requirement a user can opt for any of the three models. Let us discuss in brief about SaaS vs IaaS vs PaaS
SaaS: Software as a Service
SaaS providers host an application and targeted the end users through the internet, usually user need
to log into the cloud service through a browser and start using the service. The most familiar examples
that users commonly interact with are Gmail, Dropbox, Salesforce, Google Docs, Microsoft 365, etc.
Working: SaaS providers usually work on the Subscription model, you pay for what you consume.
As SaaS uses the web delivery model, reduces the need to install and run applications on individual
computers. With SaaS, the user does not need to setup or maintain the software themselves as Saas
provides the ‘on demand’ infrastructure for software and reduces the cost and time for deploy-
ment. In addition, Saas maintains the background infrastructure and offers a high percentage of ‘up’
time which enables the users to always be productive. Some SaaS providers may give free trials for a
limited period or provide some feature s for free to try out.
