Yes, there can be limitations on the number of users or clients that a SaaS platform can handle. The ability to handle a large number of users depends on various factors such as infrastructure, scalability, and performance. Modern SaaS platforms often use cloud technologies, which provide the necessary infrastructure to handle high user loads. The cloud allows for easy scaling, both horizontally and vertically, enabling the platform to accommodate a growing user base. Horizontally scaling: Horizontal scaling refers to adding more servers or instances to distribute the user load across multiple resources. This means that as the number of users increases, the platform can spin up additional server instances to handle the load, ensuring a smooth user experience. Vertically scaling: Vertical scaling involves upgrading the existing infrastructure by increasing the resources of the servers. This can be done by adding more CPU, memory, or disk space to handle the increased user load. Vertical scaling is useful when a single server instance can handle the user
