Description: Zonal Testing is an evaluation procedure that focuses on the functionality and performance of network zones within a network functions virtualization (NFV) environment. These tests are essential to ensure that different areas of a virtualized network operate efficiently and meet established performance requirements. In the context of NFV, where network functions are implemented as software rather than dedicated hardware, Zonal Testing allows engineers to identify bottlenecks, latency issues, and other factors that may affect service quality. These tests are conducted at different layers of the network infrastructure, assessing both the interaction between virtualized functions and their integration with the underlying physical network. The importance of Zonal Testing lies in its ability to simulate real-world conditions, enabling organizations to optimize their networks and ensure that critical applications run smoothly. Additionally, Zonal Testing is crucial for validating the resilience and scalability of applications deployed in hybrid or multicloud environments.
