Software as a Service (SaaS)

What does software as a service mean?

Software as a Service, briefly SaaS, is a software delivery model in which applications are delivered as a service over the Internet. Instead of installing and maintaining software on their own computers or servers, users access the software over the Internet, usually via a web browser.

So while at SaaS If the operator is an external service provider for IT infrastructure and software, IaaS (Infrastructure as a Service) only provides infrastructure services, such as virtualized IT resources such as operating systems. PaaS (platform as a service), on the other hand, are cloud-based services that help create applications on a SaaS platform.

What makes Software as a Service stand out?

• Accessibility: SaaS-Applications are available anytime, anywhere, as long as there is an Internet connection.
• Subscription model: It is often used on a subscription basis, e.g. monthly or yearly. This eliminates the need for large initial investments.
• Maintenance and updates: The service provider provides maintenance, security updates, and the provision of new features.
• scalability: SaaS solutions are easy to scale to meet user needs.

What are the advantages and disadvantages of software as a service?

One SaaS-Application can reduce costs because there is no need for expensive hardware or your own IT infrastructure. It is also easy and flexible to use because, on the one hand, access is possible via various devices and platforms and, on the other hand, users can adapt and expand the services as required. Automatic updates are guaranteed through continuous software updates and improvements by the provider.

However, this also has the disadvantage of dependency on the provider, as users depend on the provider's availability and security measures. In addition, access to the software is linked to a stable Internet connection. Concerns may arise with regard to security and data protection because sensitive data is stored in the cloud.

SaaS: Benefits and benefits for small and medium-sized enterprises

Since SaaS applications involve comparatively lower costs and manpower, they are ideal for small and medium-sized companies. At the same time, they achieve a standardization of processes that can support company growth and focus on the essentials.

The model is made available via the Internet and the SaaSprovider covers all hosting, so there is no cost to implement the application or other hardware. The set-up effort is ultimately minimal or even non-existent. The time and costs required during use are also low, as, on the one hand, no special technical expertise is required in the company itself and, on the other hand, administration remains low. In particular, this saves personnel costs and enables cost control in general.

In addition, a SaaS-Application with the feature of high scalability. Depending on requirements, additional licenses can be added or existing ones reduced, reducing running costs to a minimum. Only what is actually used is paid for. In addition, the application can be deployed and used both anytime and anywhere. All you need is an internet-enabled device.

Lastly, safety should be mentioned. Small and medium-sized companies save themselves high costs and effort through complex system maintenance, because SaaS-Application is updated by the operator independently and at regular intervals and security gaps are closed.
