Every businessman whether small or big seeks new methods to cut his business costs to earn more profits. Today, the hot topic among every businessman is “The Cloud.” The cloud computing service model helps entrepreneurs in doing so. This service model helps them in switching from their physical resource management to virtual resource management.
But, the main thing is which cloud computing solution will be the most suitable for a particular business? As a business, if you want to switch from physical resource management to a virtual one, then you will have to act wisely while choosing the best cloud computing service model. Well, from this piece of writing you can gather plenty of information on this topic.
Before we move on to the definition and the difference between SaaS, PaaS, and IaaS, let us first know about cloud computing.
In simple terms, cloud computing means computing services’ delivery – including servers, database, storage, software, intelligence, analytics, and networking in the clouds while using the Internet. Cloud computing solution offers faster innovation, economies of scale and flexible resources.
On using the cloud services, you pay only for those services that you use, which helps you in running your infrastructure very efficiently, lowering your operating expenses, and scaling as per your business requirements.
As per the business needs, you can either build a cloud for your organization (enterprise cloud) or can use the clouds that are being accessed commonly by various businesses (public cloud).
Cloud computing has three famous building blocks – SaaS, PaaS, and IaaS. All three models fall under the public cloud category and are being used by various businesses all over the world.
Below is a detailed overview of each model along with its pros and cons. In the end, differences amidst all the three have been discussed.
SaaS is the most commonly used model. There are certain apps that are managed by 3rd party vendors. Via the internet, SaaS delivers those apps to its users. Using the web browser, most of the SaaS apps can be run directly. This means that the client-side need not have to install or download those apps. Using their web browser, they can be easily run.
As SaaS is a web delivery model, on using this model, you need not have to hire IT staff to download as well as install apps on every computer of your office. With SaaS, you can manage all the probable technical issues like middleware, data, storage, and servers and efficiently maintain your business activities.

PaaS is that cloud computing service model where an app software platform and hardware are being provided by a 3rd party or another party over the internet. PaaS provides a flexible, cost-effective, and complete cloud platform to develop, run and manage both simple and complex apps. At its own data center, the PaaS model provider hosts servers, storage, networks, OS software, development tools, and databases.
The PaaS delivery model is more or less similar to that of the SaaS delivery model. The only thing that is different between the two is that SaaS delivers apps over the internet, while in the case of PaaS you get a platform to create software. The delivery of this platform is done through the web; hence you can build software without the need of worrying about software updates, operating systems, infrastructure, or storage.
When can PaaS be used?
PaaS can be used in situations where:
PaaS Core Benefits
IaaS is the third cloud service model providing essential computing infrastructures like storage, networking, and server resources. In simple words, IaaS can be also said as a tool to maintain a data center on the clouds. With IaaS from examining big data to hosting websites can be done easily. Clients get complete freedom to download and use tools and OS as per their choice on the provided infrastructure.
Cloud computing services like virtual storage, network, and operating systems are all delivered by IaaS products. With the help of this platform, developers can handle servers, hard drives, virtualization, networking, and storage efficiently.
When can IaaS be used?
IaaS can be used in situations where:
IaaS Core Benefits
The three cloud service computing models have their own characteristics, benefits, and limitations that make them different from each other. Now, we will differentiate all 3 models to know which platform is best for which business.
IaaS v/s PaaS
The IaaS app is a cloud-native app, whereas the PaaS app is cloud-ready. Being PaaS highly scalable, any platform can be used to run an app. While, in the case of IaaS, a cloud environment is used to create the app and then you can enjoy the cloud functionality benefits.
PaaS v/s SaaS
With SaaS, you get a readymade solution because of which your developers need not have to put in their extra efforts. Everything is handled by the SaaS vendors. While in the PaaS model developers get complete flexibility to build their own solution. Features like scalability, user-friendliness, and customization are required by PaaS.
SaaS v/s IaaS
No developer input is required to run SaaS apps as they can be run directly via online browsers. Being plug-and-play, SaaS products are perfect for every company.
Whereas in IaaS, users get access to the operational and management settings of the app. This is the reason why IaaS products are preferred more in comparison to SaaS products.
