SaaS vs PaaS: A clear guide to understanding the two models
PaaS is a way to go if you want to have bigger control over your software development without the concern about infrastructure management. It enables innovative development and scalability, supporting businesses anticipating growth and needing tailored solutions. Assessing business needs is a critical step in deciding between SaaS and PaaS. SaaS may be the ideal choice if your business prioritizes ease of use, quick deployment, and minimal technical maintenance. It provides ready-to-use applications that can streamline operations without requiring extensive IT resources. While SaaS offers numerous advantages, it also presents certain limitations that businesses must consider.
SaaS products are completely managed by the service provider and come ready to use, including all updates, bug fixes, and overall maintenance. Most SaaS applications are accessed directly through a web browser, which means customers don’t have to download or install anything on their devices. Software as a Service (SaaS) is a cloud computing service model in which the provider develops and manages the software in the cloud environment, takes care of its maintenance, updates and support. As a customer you get the ready-made product – the software – the rest is the provider’s responsibility. Selecting between SaaS and PaaS depends on a business’s specific needs and capabilities.
Key Features
Gone are the days when you had to purchase CDs/DVDs (or floppy disks if you are as old as us) and load heavy software onto your computers. Or pay for expensive data centers and servers to develop your customized applications. A lot has changed in the business world with the growth of cloud computing services in recent years. ‘As a service’ refers to the way IT assets are consumed in these offering and to the essential difference between cloud computing and traditional IT. As opposed to SaaS or PaaS, IaaS clients are responsible for managing aspects such as applications, runtime, operating systems, middleware, and data. However, IaaS providers manage the servers, hard drives, networking, virtualization, and storage.
The deployment complexity of PaaS is somewhat intermediate what differentiates paas from saas when considering the three cloud service models, as it is less straightforward than SaaS but significantly easier than IaaS. This is because PaaS platforms often provide built-in development tools, CI/CD pipelines, and integrated databases. IaaS delivers cloud computing infrastructure, including servers, networks, operating systems, and storage, through virtualization technology.
- Instead, they store data on the servers of IaaS providers, and use a dashboard or API (application programming interface) to access and manage their resources.
- Whether you’re a small business owner, developer or you’re just curious, this article will give you a clear idea of how these models operate.
- Customers would still need to build out their own tech stack, making IaaS more similar to using on-premise systems from a practical standpoint.
These limitations highlight the importance of careful evaluation when considering SaaS for business operations. Furthermore, businesses may encounter integration challenges connecting SaaS applications with existing on-premises systems. Moreover, comprehending SaaS and PaaS enables better strategic planning, ensuring that technology investments align with long-term business objectives. Ultimately, this understanding aids in leveraging cloud computing efficiently, driving innovation, and maintaining a competitive edge in the digital landscape. These tools can either be used as a web app (such as Google Docs) or downloaded and installed on the device (such as Adobe Creative Cloud). With a SaaS app, there’s no need for a specialist to come in and manually install it on each laptop using a purchased license.

The cloud allows software and services to run on the internet instead of only locally on one device because the data is stored remotely across various servers. PaaS solutions abstract away the complexity of provisioning and running infrastructure. Developers used to set up servers manually by configuring the operating system, installing their programming language’s runtime environment, and configuring admin tasks such as backups and monitoring.

Each type of cloud computing leaves you less and less on-premise infrastructure to manage. Compared to traditional IT, IaaS gives customers more flexibility build out computing resources as needed, and to scale them up or down in response to spikes or slow-downs in traffic. IaaS lets customers avoid the up-front expense and overhead of purchasing and maintaining its own on-premises data center. IaaS, PaaS and SaaS are the three most popular types of cloud service offerings.
SaaS, PaaS and IaaS Providers
The service provider manages all hardware and software, reducing the need for local installations and IT specialists. Its advantages include reduced upfront costs with pay-as-you-go pricing, flexibility to build and adjust resources, and scalability to handle traffic changes. The following table highlights key examples of each type, showcasing their unique advantages—from ready-to-use applications and development platforms to scalable virtualized infrastructure solutions. The service provider handles all technical aspects, including data, middleware, servers, and storage, making maintenance and support easier for the business. PaaS is where many Software as a Service (SaaS) applications are developed.
In each case companies consume IT resources on-demand from external cloud providers, instead of purchasing physical assets like hardware equipment and software licenses outright. Cloud-based services have transformed IT by offering infrastructure, platforms, software, and applications online. However, SaaS companies deliver their software or apps to the end-user, whereas PaaS gives you a platform to build customizable apps. The PaaS provider manages the underlying infrastructure (servers, storage, networking) and handles the complexities of operating systems and software updates.
With PaaS and IaaS, however, users must manage their own data use and applications. SaaS and PaaS providers manage organizations’ operating systems, but IaaS users must handle their own operating systems. In contrast to on-premise systems, these are simple to access via any web browser or online app.
(Google Cloud has highly scalable resources that can be scaled to fulfill demand spikes.) But this of course requires significant expertise in system administration and resource management to achieve. As you might’ve guessed, this is the model with the highest customization capabilities. Users will have full control over the whole infrastructure including Operating Systems, software, and configuration settings.
