Q: How does a user typically consume a SaaS application?

A user accesses a SaaS application within a multi-tenant architecture, where multiple users access the same pool of resources. Each user has their own dedicated space to securely store their data. This setup offers cost efficiency and streamlined management by the cloud service provider.
