In cloud computing and virtualization, managing memory effectively is critical for ensuring the optimal performance of virtual machines (VMs). Virtualized platforms allow multiple VMs to run on a single physical server, maximizing hardware utilization. However, with this power comes the challenge of managing resources efficiently, especially memory. One technique that has gained prominence is memory overcommitment, which allows more memory to be allocated to VMs than is physically available on the host server. While this helps optimize resource use, it can lead to memory-related performance issues if not carefully managed….
