FAQs
What distinguishes SaaS from traditional on-premises software?
Unlike traditional software that requires local installation and management, SaaS applications are hosted by the vendor and accessed over the internet, typically through a web browser or mobile app. This cloud-based delivery model eliminates the need for businesses to invest in expensive hardware and IT infrastructure, while also reducing maintenance and upgrade responsibilities.
How does the multi-tenant architecture of SaaS work?
In a multi-tenant SaaS architecture, a single instance of the application serves multiple customers or tenants simultaneously. Each tenant’s data is logically partitioned and isolated, ensuring privacy and security. This approach enables SaaS providers to efficiently manage and update the application centrally while offering scalability and cost-effective pricing models.
What are the main advantages of adopting a SaaS solution?
Key advantages of Software as a service include lower upfront costs, scalability and flexibility, automatic updates and maintenance, enhanced mobility and collaboration, reduced IT overhead, and improved data security and compliance when working with reputable providers.
