SaaS vs PaaS: What is the Difference Between?

PaaS is a form of SaaS, where you host the software as well as the underlying infrastructure. It’s often offered on a pay-as-you-go basis, where you only pay for what you use. SaaS is a subscription-based model, where you pay a fee to use the software as part of a service.

He’s written several world-recognized books on software configuration, speaks Spanish, ballroom dances, and owns The Product Company and Squibler. What separates Lumen5 from other video makers is the speed with which their application converts to text. Founder and CEO, Laurel Taylor, started the company as a means of finding a solution to the student debt crisis in the U.S.

Examples of SaaS

Startups and small companies may prefer IaaS to avoid spending time and money on purchasing and creating hardware and software. Business and technical requirements that drive decisions for a specific PaaS solution may not apply in the future. If the vendor has not provisioned convenient migration policies, switching to alternative PaaS options may not be possible without affecting the business. Due to multiple services management, time-consuming is more in PAAS when compared with SAAS. To put it simply, if you want to build an app for your business, you would need a PaaS product. You can easily create large, complex applications without downloading the related infrastructure.

The software or application needed has to be downloaded in SAAS, whereas in PAAS, the application is built by the user. PAAS users are mostly developers, whereas SAAS users need not be developers always. Applications and Data are managed by users in PAAS, while in SAAS, all the requirements are managed by a third party.

With SaaS, businesses don’t have to install or download any software to their existing IT infrastructures. SaaS ensures that users are always running the most up-to-date versions of the software. For example, you can build your own web application to suit your business using the platform provided by PaaS. It is a cloud computing service category providing a wide range of hosted capabilities and services.

These controls are not limited to the software–in terms of the version, updates, or appearance–but also the data and governance. Customers may therefore need to redefine their data security and governance models to fit the features and functionality of the SaaS service. Since a one-size-fits-all solution does not exist, users may be limited to specific functionality, performance, and integrations as offered by the vendor. In contrast, on-premise solutions that come with several software development kits offer a high degree of customization options. Due to its web delivery model, SaaS eliminates the need to have IT staff download and install applications on each individual computer. With SaaS, vendors manage all potential technical issues, such as data, middleware, servers, and storage, resulting in streamlined maintenance and support for the business.

On-premise IT infrastructure presents the biggest level of responsibility to you as a user and manager. When your hardware and software are all on-premises, it’s up to you and your team to manage, update, and replace each component as needed. What cloud computing allows for is the allocation of one, several, or all of the parts of your infrastructure to the management of a third party, freeing you up to focus on other things. “As-a-service” generally means a cloud computing service that is provided by a third party so that you can focus on what’s more important to you, like your code and relationships with your customers. Each type of cloud computing leaves you less and less on-premise infrastructure to manage.

IaaS vs. SaaS

For those with little knowledge about system administration, it is better to use SaaS instead as it is more straightforward. One of the most common types of platforms used by organizations is a development framework known as PaaS. A good way to understand the concept of the SaaS model is by referring to a bank. This type of bank provides its customers with secure and reliable services while protecting their privacy. The main types comprising the cloud computing platforms that are available today include PaaS, IaaS, and SaaS.

Consider building an app on your local drive, then trying to deploy it online — that’s difficult or might take too many steps. You have to make sure that your apps and operating systems are working properly and providing the utmost security. Software updates, bug fixes, and general software maintenance are handled by the provider and the user connects to the app via a dashboard or API.

PAAS does not rely upon any other service as its platform, while SAAS relies either on IAAS or PAAS for its platform service. You are a large organization that pros and cons of paas wants to manage and coordinate employees and freelancers globally. You use an app whose demand spikes and reduces significantly—for example, taxation software.

One term you’re likely seeing more frequently in the world is XaaS, short for Everything as a Service. Larger companies may prefer to retain complete control over their applications and infrastructure, but they want to purchase only what they actually consume or need. PaaS may not be a plug-and-play solution for existing legacy apps and services. Instead, several customizations and configuration changes may be necessary for legacy systems to work with the PaaS service.

Users pay a monthly or annual fee to use a complete application from within a web browser, desktop client or mobile app. The application and all of the infrastructure required to deliver it – servers, storage, networking, middleware, application software, data storage – are hosted and managed by the SaaS vendor. Organizations can run their own apps and services using PaaS solutions, but the data residing in third-party, vendor-controlled cloud servers poses security risks and concerns. Your security options may be limited as customers may not be able to deploy services with specific hosting policies. IaaS is about managing cloud-hosted computing resources — servers, networking, and storage.


For IaaS, key users need to be skilled in running a virtual machine and infrastructure. The key users of SaaS systems are end-users – the people who log into and make use of the platforms. The key users of IaaS systems are network architects and IT administrators – the people who are responsible for administering and maintaining the platform. Software as a Service, or SaaS, is the solution we find most people are familiar with, just as they use these technologies in their day-to-day lives.

  • You typically pay a monthly fee to access these resources based on your specific services and how much you use them.
  • The providers will then host the software and hardware on their own infrastructure and deliver this to their users as an integrated solution.
  • On the other hand, PaaS is hosted anywhere in the system and managed through a remote server.
  • Build out backend IT infrastructure on the cloud using IaaS, and use it to build its own development platform and application.

The cloud service provider then manages all of your services and applications. This is because the CSP hosts and manages all the back-end IT infrastructure and software development frameworks that include OSs, middleware, databases, and runtimes. While this gives developers greater flexibility and ease of operation, they don’t have control over development environments.

Like IaaS, the CSP hosts and manages all the hardware, including servers, networking, and storage resources. The key users manage applications and data while the service provider manages runtime, middleware, O/S, virtualization, servers, storage, and networking on PaaS. On IaaS, the key users manage applications, data, runtime, middleware, and O/S while the service provider manages virtualization, servers, storage, and networking. Infrastructure as a service is used by companies that don’t want to maintain their own on-premises data centers.

SaaS saves valuable business resources otherwise spent on hiring staff to install, download, and update these applications on multiple computers. Scaling the application development infrastructure in an on-premises setup can be wasteful and expensive. However, with PaaS, you buy only the additional capacity and begin to use it immediately. You can access a wide range of resources such as OSs, middleware, databases, and development tools that would otherwise be expensive to purchase and own in an on-premises setup. Developers can use PaaS to create custom software which can be provided via the cloud via an API.

Both can be great solutions for businesses of all sizes, but they are very different. BMC works with 86% of the Forbes Global 50 and customers and partners around the world to create their future. Similarly, customers must rely on the vendor to ensure that VMs are adequately isolated within the multitenant cloud architecture.

IaaS vs. PaaS vs. SaaS: Here’s What You Need to Know About Each

These products make it easier for developers to construct custom applications since they don’t have to outsource for data storage and management. Microsoft Azure is an IaaS product and cloud computing platform that makes it possible for customers to create, manage, and test applications via a cloud host. Typically IaaS customers can choose betweenvirtual machines hosted on shared physical hardware or bare metal servers on dedicated physical hardware. Customers can provision, configure and operate the servers and infrastructure resources via a graphical dashboard, or programmatically through application programming interfaces . While customers can run legacy apps in the cloud, the infrastructure may not be designed to deliver specific controls to secure the legacy apps. Minor enhancement to legacy apps may be required before migrating them to the cloud, possibly leading to new security issues unless adequately tested for security and performance in the IaaS systems.

XaaS: Everything as a Service

On SaaS, the key users manage nothing while the service provider manages runtime, middleware, O/S, virtualization, servers, storage, and networking. As mentioned earlier, many of these service models already include some of the capabilities of the other ones, basically getting two in the form of one. IaaS offers the central infrastructure with servers, networking, etc.

Or, you may earn a popular Professional Certificate in cloud computing, such as the Google Cloud certification on Coursera. If you are unsure about what route you should take in advancing your cloud computing knowledge, you can start with an in-depth introductory course like Introduction to Cloud Computing. Most application software under SaaS can be downloaded directly through a web browser. As a user, you benefit from not having to work through lengthy installation instructions and not having to wait for the software to download on your computer.
