SaaS and SOD differ in their deployment and delivery methods for software.
SaaS is an innovative approach where a third-party provider hosts and manages applications, accessible online through various devices. It simplifies software usage by adopting a subscription-based model, eliminating complex installations and device management. Notably, SaaS seamlessly handles processing and data storage on the provider's servers.
On the other hand, SOD is an architectural methodology for software development. It emphasizes creating modular and loosely connected services within an application. These services communicate through standardized protocols, representing distinct business functions. SOD allows independent development, deployment, and maintenance of services, offering advantages like reusability, scalability, and flexibility.
To summarize, SaaS focuses on delivering software as a centrally hosted service over the internet, while SOD emphasizes creating modular services within a software system.
