What is SaaS?
SaaS stands for “software as a service” and basically means that you no longer install software on your computer, but completely simply use over the Internet. You can open these programs in your browser at any time, that's all you need. You usually pay a monthly or annual fee and therefore always have access to the latest version.
This is attractive because users no longer have to worry about updates or new versions. It is no longer possible to work with an outdated version. On the server side, the providers ensure that the Continuously advancing the development of their SaaS and is played out to customers without the need for action there.

Well-known examples: This is what SaaS looks like in everyday life
- Microsoft 365: Office software with Word, Excel and PowerPoint, all files are in the cloud.
- Google Workspace: Comparable to Microsoft 365, Google Docs, Google Sheets, Drive storage, etc.
- Slack: Communication tool that you use in your browser or as an app. For team chats and conversations (huddles).
- Salesforce: One of the most well-known customer relationship management (CRM) services.
- Zoom: Online meetings without installation, or alternatively as an app.
Most companies commit to specific SaaS products for every purpose. For example, in the combination of Google Workspace and Slack — but not Microsoft 365 in parallel.

How does SaaS development work in practice?
SaaS development is complex and, as described, will not be discontinued after the first live version. Quite the contrary: In order to survive on the market, the software products are constantly being developed. The following process provides an overview of the basic development steps of a SaaS.
Idea & concept
It starts with a business idea or a problem that needs to be solved. It validates whether there is a market and whether people would be willing to pay money for the solution. This also clarifies what the pricing model could look like (e.g. monthly subscription, freemium model, etc.).
Design & architecture
As soon as it is clear what is being developed, structural planning follows. The focus here is on technical implementation, hosting in the cloud and designing the database. In addition, there is the so-called Multi-tenancy architecture, so that all users can use the same software version but keep their data separate from each other.
Development (programming)
The actual implementation often starts with a agile software development. The software is developed in small steps, tested again and again and thus gradually improved.
Testing & security
Before launch, the application is extensively tested. In addition to functionality, data security also plays a major role here, as the vast majority of security is provided by the provider — quite the opposite of locally installed software, where the user was previously responsible for data and virus protection.
Deployment & go-live
After successful testing, the software is deployed in the cloud. Thanks Continuous Deployment Updates can be imported regularly and usually without noticeable interruptions.
Operation & development
After launch, the application is continuously monitored and improved. Based on customer feedback, new functions are developed and existing features are optimized. Regular updates keep the software up to date and competitive.
