Different types

Transparent Page Sharing (TPS)

Ballooning

Memory compression

Swapping

Transparent Page Sharing (TPS): Transparent Page sharing shares memory pages on the same or across multiple VMs running on the same host.

Ballooning: Ballooning: can be used when we have VMware Tools running Can cause performance increase or decrease as the Guest VM has to use its own memory technique swapping etc.

Memory compression: Host compress the memory but this has an impact as the compressed memory takes longer time to get access read/ write.

Swapping: Host swapping memory this is used as a last resort as can cause serious performance issues. The memory is written to the physical disk
