Software-as-a-Service (SaaS) design requires a deep understanding applications that leverage cloud computing infrastructure for scalability, flexibility, and cost effectiveness.
SaaS applications are accessible from anywhere, at any time, independent of the underlying infrastructure or platform hosting an application.
Unlike monolithic on-premise legacy applications, SaaS applications have to factor in considerations such as multi-tenancy, seamless cross-platform integration, and high levels of performance and availability.
