SaaS vs PaaS vs IaaS: Comprehensive Explanation, Examples & Resources
SaaS vs. PaaS vs. IaaS: What are their meanings, how do they differ and what do each of the terms signify? Read on to know your answers in detail.
As you step into the world of the e-commerce domain, the three important acronyms that you will see a comparison around are SaaS vs. PaaS vs. IaaS. If you are considering switching your business to the cloud, it is more important than ever to understand the differences and advantages of the various cloud services.
According to Statista, by 2020, the market of global public cloud software as a service (SaaS) is forecast to reach 157 billion U.S. dollars in size. In fact, this is more than double than it was in 2014. From a similar report by StrategyAnalytics, it is said that by 2021, the corporate mobile SaaS market will reach $7.4 billion.
Nonetheless, the cloud is a hot topic and there are usually three models of cloud service to compare namely,
Let me begin defining each of these terms, some related examples, mode of delivery, advantages, and limitations.
SaaS is often deemed as one of the most commonly used options in the cloud market. A majority of the SaaS applications run directly via your web browser. Simply put, they would not require any heavy installations or downloads to run.
And because of its web delivery model, the vendors manage all technical issues without having to download it additionally.
PaaS finds its use in many applications, while it provides cloud components to certain software. It strives to deliver a framework for develops that they can use to create customizable apps.
Additionally, the delivery mode here is quite alike SaaS, with instead a difference of delivering over the internet, it tends to deliver over a platform for software creation. Further, it allows the businesses to design apps that build into the PaaS with unique software facets.
IaaS is a fully self-reliant service for accessing networking, storage, and monitoring computers. Over and above, it permits businesses to buy resources on-demand and as required rather than buying the hardware.
IaaS mostly delivers through virtualization technology. Nonetheless, the clients can still access their servers and storage directly, although though a virtual data center in the cloud.
While it is IaaS that offers the admins with more control over operating systems, it is usually PaaS that renders users with greater flexibility and ease of operation. Further, IaaS helps base the infrastructure of a cloud-based technology. On the contrary, PaaS helps developers build custom apps that can be delivered over the cloud itself.
Simply put, imagine IaaS as the foundation of building a cloud-based service. Be it software, content, or the website to sell a physical product. Whereas, PaaS helps the developers to build apps without actually having to host them.
In the bigger picture, PaaS products are used as the foundation for building new apps on top of the platform’s network. SaaS products are controlled by another company. Right from the applications to the data till the servers.
Moreover, PaaS is better for companies looking to build a solution on an existing network. And SaaS is best for companies looking for a really easy way of computing and usability.
One term you’re likely seeing more frequently in the world is XaaS or Everything as a Service. XaaS refers to the highly-individualized, responsive, data-driven products, and offerings that are fully controlled by customers.
And the data they provide via everyday IoT-powered sources like cell phones and thermostats. By using that data generated over the cloud, businesses can innovate faster, deepen their customer stickiness, and sustain the sale beyond the initial product purchase.
When it comes to SaaS vs. PaaS vs. IaaS, you must know that each of the cloud models offers unique functionalities and facets. As an organization, you must know the differences and how to implement them.
Moreover, whether you are looking for cloud-based software for multiple storage options. Or if you wish to create customizable applications or you want to take complete control over the entire infrastructure – there is a cloud service for each one of these.
Nevertheless, the comparison between these cloud services will be in the air. No matter whichever option you prefer, migrating to the cloud seems to be the future of the technology and business ahead. As they render the user with the flexibility, choice and comfort that usually on-premise cannot provide – at least not all of it.
