Cloud – a hot topic nowadays for both small and big businesses. According to a report by Marketsandmarkets, the global cloud computing market size is expected to grow from USD 445.3 billion in 2021 to USD 947.3 billion by 2026, at a CAGR (Compound Annual Growth Rate) of 16.3% during the forecast period. Also, Multisoft says that 80% of the companies that move to cloud notice improvements in their IT departments in the first six months.
If you consider making the switch to a PaaS or SaaS software, it is important to understand the difference and the advantages of them.
PaaS and SaaS are two main types of cloud computing.
Platform as a service (PaaS) is a complete development and deployment environment in the cloud. It has resources that enable you to deliver everything from simple cloud-based apps to complex, cloud-enabled enterprise applications. A third-party provider delivers users hardware and software tools. The resources are purchased on a pay-as-you-go basis from a cloud service provider. All you need to access them is a secure Internet connection. Instead of working on a computer on site, it is possible to log-in from anywhere and collaborate on projects.
With a PaaS, developers don’t need to install in-house hardware and software to develop and run new applications. With PaaS, you don’t need to buy and manage software licenses, middleware, application infrastructure, development tools or other resources. PaaS allows businesses to create and design apps built with special software components. These applications, are scalable and highly available as they take on certain cloud characteristics.
Software as a service (SaaS) is a type of software delivery that allows users to access data from any device that is connected to the internet. Basically, SaaS users use and connect to cloud-based applications on the Internet, which means that they don’t need to download software on their desktop, or run updates. Usually, SaaS subscriptions have a pay-as-you-go model with a recurring fee (monthly or annually).
PaaS works by delivering all development tools in one online interface. PaaS solutions are more suitable for software development purposes. PaaS eliminates the need to work from a specific computer.
A PaaS solution has three main parts:
PaaS delivers all standard development tools online through the graphic user interface, where the developers can collaborate on projects. This enables streamlined workflows and multiple operations.
SaaS works as an on-demand computing software delivery model. It gives users network access to applications. SaaS is provided on a hosted platform, which means that the administrator doesn’t need to worry about updates, and has no connection to the hardware. Because of this, SaaS reduces the cost and time for deployment, removes some risks of operation, and also reduces the cost of operation.
SaaS can be deployed in three different models:
There are three main types of PaaS:
There are two types of SaaS:
The difference between PaaS and SaaS lies in the level of service they provide. PaaS gives you the infrastructure to create your own applications, while they and the data is fully under your control, and SaaS provides you with a total package, including the application itself and the data storage.

Overall, both PaaS and SaaS come with several advantages for users. Let’s take a look at them:
Depending on your business needs, you might want to pursue one or multiple types of cloud services. It is crucial to consider what your future goals are and how you want the solution to enhance your operations.
