# IoT IP Overlay Network Security Performance Analysis with Open Source Infrastructure Deployment
## 5 Implemented Scenarios and Experimental Results
* Dynamic Resource Allocation: Proxmox dynamically adjusts resources based on current workload demands, optimizing CPU and memory usage. * CPU Hotplug: This allows one to add CPUs to running VMs without downtime, providing flexibility and scalability. * Integration with cgroups and namespaces: This ensures fine-grained control over resource allocation and isolation in containers, optimizing CPU usage. Proxmox VE's optimizations in both network and CPU management layers ensure nowadays that virtualized environments operate with high efficiency and performance. The comprehensive support for advanced networking technologies combined with robust CPU management techniques makes Proxmox VE a powerful platform for modern data centers and cloud environments.
