SaaS- What is that?

Software as a Service

SaaS (Software as a Service) is a cloud computing model in which software applications are delivered over the internet and hosted by a third-party provider. Instead of installing software on local computers or servers, users can access SaaS applications via a web browser. The SaaS provider manages, maintains and updates the software.

Functions of SaaS

  • Web-based access: SaaS applications are accessible via the Internet, so users can access them from anywhere and from any device with an Internet connection.
  • Automatic updates: The SaaS provider ensures regular updates and maintenance of the software so that users always use the latest version without having to update manually.
  • Scalability: SaaS applications can be scaled according to user needs, both in terms of the number of users and the range of functions.
  • Subscription-based pricing: SaaS is typically offered on a subscription basis, where users pay a monthly or annual fee to use the software.

Advantages of SaaS

  • Cost efficiency: As no expensive hardware or software licenses need to be purchased, SaaS is often cheaper to buy and maintain. There are no costs for servers, maintenance or infrastructure.
  • Ease of implementation: SaaS applications do not require complex installation or configuration, which speeds up and simplifies deployment.
  • Accessibility: Users can access the software from different devices and locations, which promotes collaboration and mobility.
  • Maintenance-free for the user: The provider takes care of all technical management, including security, updates and backups.

Examples of SaaS

  • Office 365: A suite of office applications such as Word, Excel and PowerPoint that are available online.
  • Google Workspace: A collection of productivity tools, including Google Docs, Gmail and Google Drive.
  • Salesforce: A CRM (Customer Relationship Management) platform that helps companies manage their customer relationships
  • Dropbox: A cloud-based storage and file sharing service.
