Though all the three technologies empowers corporate sector to help professionals access their networks remotely. However there are some conceptual differences amongst the three technologies you should know.

User experience/ Interface

Virtual Private Network

The remote user gets personalized experience because he uses applications on his desktop. The applications interact with the central network. The user experience is personalized.

Remote Desktop Services

The user remotely accesses the central server. So the user experience of all the users is same as the server. User does not get personalized experience

Virtual Desktop Infrastructure

Through virtual desktop experience is personalized. The virtual desktop creates operating system experience same as the client.

User experience/ Interface
Unit economics

Virtual Private Network

V.P.N. networks are recommended for small and medium businesses. However a lot of large businesses also use VPN.

Remote Desktop Services
Remote desktop services are best recommended with medium and large enterprise that use heavy weight applications.

Virtual Desktop Infrastructure
VDI infrastructure is a slightly complicated affair. It is best for the large businesses that want to cut the cost of client side infrastructure

Maintenance

Virtual Private Network

The client normally installs a VPN application. The network is established on authentication and it is done. Lowest on the maintenance part.

Remote Desktop Services

Relatively higher maintenance. However with less machines comes less patching and maintenance.

Virtual Desktop Infrastructure
Very high maintenance. The software and hardware application make the infrastructure complicated.

User experience/ Interface
Performance

Virtual Private Network

The performance is always dependant on the user hardware. Same transactions take more data transmission in VPN.

Remote Desktop Services

In all the three, remote desktop services fall between the VPN and VDI.

Virtual Desktop Infrastructure

Because of compartments of resources Virtual Desktop Infrastructure guarantees the fastest user experience.

Security

Virtual Private Network

The process of data encryption secures the data while it is traveling through the network

Remote Desktop Services

RDS does only allows the data to remain on the server. The user machine does not store anything. Hence even if the user machine is lost or goes in wrong hands etc , the data is never lost.

Virtual Desktop Infrastructure

Exactly similar to RDS, VDI also stores all applications, and data on its centralized server. Hence even if the user machine is lost the data is never lost.

Conclusion:

Hence, remote access industry is growing at a very fast pace. The three segments of remote namely VPN, RDS and VDI have similar application. Consequently, the remote access usage, number of users, the centralized server etc are the factors that help us identify which solution is the best for which corporate. For this reason, I strongly recommend to all IT administrators in corporate houses to consult a network infrastructure professional in brief before deciding on which technology to go for .
