Table 1: Edge resource metrics. era, high serviceability at the edge of the network is seen as a crucial foundational criterion for a successful Internet of Things paradigm. A software-defined implementation with high availability and durability of hardware and storage media is recommended. **Security and Privacy:** Content perception, real-time processing, and parallel processing are some of the ways in which edge computing differs from more traditional forms of computing, and this difference has led to new challenges in the area of data security and privacy protection [40]. There is a large attack surface on edge resources, so security countermeasures need to be effective and efficient. DoS attacks, penetration techniques, and physical break-ins are all part of this category. Since manual patches can have an impact on performance, automated remote patching is an absolute necessity from a security perspective.
