Traditional Service-Oriented Architecture (SOA) faces growing limitations in flexibility, adaptability, and intelligence, failing to meet modern enterprises' evolving demands. This paper proposes the Internet of Intelligent Services (IIS) and the Agent Software Factory (ASF) as solutions. IIS transforms conventional services into intelligent, autonomous, and dynamically collaborative entities, guided by principles of decentralized autonomy, dynamic adaptation, and semantic modeling with feedback-driven learning. Built on IIS, ASF enables end-to-end automation of the intelligent agent lifecycle via specialized assistant agents. Furthermore, this paper presents the INNOVATORS framework, a structured analysis of ten transformative SaaS trends that characterize this new era. Drawing on industry observations and technological foresight, the framework encompasses: I - Immersive Experience as a Service (IEaaS), N - Niche Market focus, N - Normal Business Enabler tools, O - Office Platforms for Collaboration and Business, V - Vertical Industry Solutions, A - AI Plugin Everywhere, T - Transformation Software, O - Orchestrated SaaS Development Platforms, R - Recognition of Data Insights, and S - Service-to-Service (S2S) integration. To support S2S collaboration among heterogeneous agents, the Agent Service Bus (ASB) is proposed, featuring a layered architecture for standardized access, intention-driven scheduling, and dynamic orchestration. Together, these innovations provide a foundational framework for intelligent, adaptive, and service-centric enterprise software systems.
