Spagic 3: OSGi Universal Middleware for an effective SOA solution
1 like•652 views
The document outlines the features and goals of Spagic 3.0, an open-source universal middleware solution designed to address the challenges of system complexity and promote interoperability in service-oriented architectures (SOA). It emphasizes modularization, lifecycle management, and orchestration to enhance service reuse and integration. Additionally, it details governance, monitoring, and development processes within the framework to support efficient service implementation and management.
