Transparent page sharing (TPS) - removes redundant pages with identical content
Ballooning - artificially increases the memory pressure inside the guest
Memory compression - compresses the pages that need to be swapped out Hypervisor swapping - ESXi directly swaps out the virtual machine’s memory
Swap to host cache (swap to SSD) - reclaims memory by storing the swapped out pages in the host cache on a solid-state drive
