Virtual Trusted Platform Module – vTPM 

Trusted Computing Group (TCG) introduced TPM in 2009. A Trusted Platform Module (TPM) is a microchip that is often built into the motherboard to provide hardware-based security. This can be also be added later for customized systems if your motherboard supports it. A TPM chip is a secure crypto-processor that is designed to carry out cryptographic operations. If you are using BitLocker encryption on a computer with the TPM, part of the key is stored in the TPM itself, rather than just on the disk. This means that an attacker can't just remove the drive from the computer and attempt to access its files elsewhere.

In Windows server 2016 Hyper-v and Windows 10, you can enable vTPM into a VM. Virtual instance will be mapped to each VM, as shown in the following diagram:

This is what the hardware TPM chip looks like:
