PaaS (platform as a service) and SaaS (software as a service) are cloud-based software solutions and often confused. The truth is that while there can be some overlap in how these two offerings work, PaaS vs SaaS are not identical. Typically, PaaS is responsible for software development, and SaaS focuses on implementing cloud computing. In this article, let’s look at what these two systems provide and what differentiates PaaS from SaaS at all.
SaaS at the glance
Software as a service (SaaS) is how applications are delivered over the Internet – as a service. It provides simple online access without software installation and maintenance, not to mention complex hardware management. SaaS applications are also known as on-demand software or hosted software. But either the name of software as a service, specific.
SaaS providers’ servers manage the applications in terms of performance and availability. It is worth mentioning that SaaS stands out from other applications at the expense of improved access to data, easy customization, and advanced infrastructure.
Definition of PaaS
Platform as a service (PaaS) is determined as a specific cloud computing model providing delivery of needed software or hardware tools via the Internet by a third-party provider. Different sets of tools are usually required to develop the applications. The main feature of PaaS is that a provider is responsible for hosting the hardware or software on his infrastructure. In conclusion, this relieves developers from installing in-house software and hardware. The main benefit of PaaS solutions is convenience and simplicity in functionality for multiple users.
The difference between SaaS and PaaS
When comparing SaaS and PaaS solutions, we can notice several key differences. Here are the most common:
- PaaS uses applications not in the public cloud, while SaaS utilizes applications placed in various public clouds.
- PaaS applications are easily customized and might be created depending on the developer’s preferences. On the other hand, SaaS applications cannot be customized or only in exceptional cases.
- In PaaS, both the developer and the third-party vendor can control the servers, networking, and servers. SaaS provides a third-party provider’s ability to handle all the mentioned aspects.
- Data in PaaS is easily portable from other applications, while SaaS doesn’t offer to transfer data from other providers across the software.
- PaaS allows building hardware or software that is based on the developer. At the same time, SaaS utilizes software that a vendor already creates.
- In PaaS, the developer ensures the software application while SaaS provides software applications at the expense of the network.
- PaaS offers more security by the application, but SaaS uses applications from vendors that reduce the overall security.
- PaaS provides faster and easier deployment, development, and testing processes than SaaS.
- PaaS is not available on a subscription basis, while SaaS ensures this offer.
