Midrange
Simply put, the midrange is half of the data set’s range. Similar to the mean, the midrange is sensitive to the extreme values and hence the prospective outliers. However, unlike the mean, the midrange is not sensitive to all the values of the data set that lie in the middle. Thus, it is prone to...

Edge computing dynamically organizes geo-distributed nodes into micro clouds, enabling "infrastructure as software" for real-time applications. This model adapts cloud principles for efficient, location-aware resource management at the edge.
Area of Science:
- Computer Science
- Distributed Systems
- Cloud Computing
Background:
- Edge computing brings cloud services closer to users, enabling new applications but posing challenges in geo-distributed resource management.
- Real-time applications necessitate multi-tier infrastructure for local data preprocessing and cloud-based heavy computation.
Purpose of the Study:
- To present a model for dynamically organizing geo-distributed edge nodes into flexible micro clouds.
- To enable resource reorganization for optimal service delivery based on population needs and location advantages.
Main Methods:
- Adapting cloud organization principles for edge environments.
- Developing a descriptive model for specifying desired infrastructure states.
- Implementing dynamic resource reorganization for elasticity.
Main Results:
- A model capable of organizing geo-distributed nodes into adaptive micro clouds.
- Abstraction of edge infrastructure to a software level, enabling "infrastructure as software" at the edge.
- Demonstration of elasticity through dynamic resource reorganization.
Conclusions:
- The proposed model facilitates efficient management of geo-distributed edge resources.
- Enabling "infrastructure as software" at the edge is crucial for future real-time applications.
- The model can be integrated with existing tools, allowing cloud providers to offer micro clouds as a service.
