What are the Differences between IaaS, PaaS and SaaS?

It is right that cloud computing is still not that popular as it was expected to. The most popular Cloud computing models in the market are IaaS PaaS & SaaS. But most businesses encounter difficulty of understanding the intricate difference between SaaS, PaaS and IaaS under the Cloud Computing realm. Since there are various Cloud Computing Service providers coming up in the market, it is very crucial to be aware of the nuances of these three models before you make your decision.

Let us discuss the capabilities of these three models and the control-level (Vendor of Self) it facilitates:

Software as a Service ( SaaS ): It is known by numerous other names like web remote software, software on the demand, software on different host etc. SaaS offers fully functional applications on-demand to provide specific services like CRM, banking services, Project management tools, CAD etc. Because of the web delivery model, SaaS eliminates the need to install and run applications on individual computers, while the provider completely manages it. Example: Netflix, Google Apps


Platform as a service ( PaaS ): Nowadays various development tools come at very high cost. Using PAAS, one enjoys easy access to development platform at very reasonable cost. Platform as a service (PaaS) automates the configuration, deployment and ongoing management of applications in the cloud. PaaS makes the development, testing, and deployment of applications quick, simple, and cost-effective. Examples: Python, Java, Eclipse


Infrastructure as a service ( IAAS ): It is the fundamental building blocks of computing resource. IaaS includes system, data storage, security etc.  The service provider creates the infrastructure, allowing the developer to create their own platform and software. It is the responsibility of the developer and not the provider to maintain and update the system. Examples: Amazon, Microsoft, VMWare, Rackspace


The cloud is a very broad concept. Each section of cloud computing has its own functionality, which is distinct from others. To derive the maximum ROI of your investment in cloud, understand, evaluate and compare the offered services in accordance with your business model, needs and budget.
