SaaS in Cloud Architecture

Understanding SaaS is important for cloud practitioners. Cloud architects encounter this concept when designing systems for reliability, scalability, security, and cost-efficiency across Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and Oracle Cloud Infrastructure (OCI).

In cloud Cloud, SaaS is one of several foundational concepts that practitioners must master to design production-ready systems. Related concepts in the same domain include the terms listed in the See Also section below.
