xApps
xApps is a term used in software engineering to denote modular, extensible applications that run on a host platform to extend its functionality. They are typically lightweight components such as plug-ins, microservices, or containerized modules that implement defined interfaces and can be independently developed, tested, and deployed by third-party developers or internal teams. The exact definition of xApp varies by ecosystem, but they share a common goal: to enable rapid customization and scalable extension of a base platform without modifying its core code.
Definition and scope: The "x" in xApp can stand for cross, executable, or extended, depending on the
Architecture and lifecycle: An xApp generally communicates with the host via clearly defined APIs or event
Security, governance, and interoperability: To mitigate risk, xApps rely on access controls, code signing, and runtime
Usage: xApps are employed across domains such as enterprise software platforms, network management and software-defined infrastructure,
