What is SaaS?

SaaS (Software as a Service) is a software delivery model where the provider develops, manages, and maintains the application, making it accessible to clients via the internet on a subscription basis. Users access the application without worrying about installation, configuration, updates, or infrastructure maintenance.

Key advantages:

• Cost reduction: No need to purchase and maintain hardware and licenses.
• Scalability: Easily adjust the number of users or resources used based on needs.
• Accessibility: Access the application from anywhere with an internet connection.
• Updates: The provider regularly updates the software without customer involvement.
• Rapid deployment: No need for lengthy installation and setup processes.

Examples of popular SaaS applications:

• Google Workspace (formerly G Suite)
• Microsoft 365
• Salesforce
• Slack
• Zoom

From a DevOps perspective, SaaS impacts deployment, monitoring, infrastructure management, and security processes. We work more closely with cloud platforms, automate update delivery processes, and support continuous service operation for end-users.
