Can i have some good VPS sites and also a tutorial on how to deploy our own VPN service on it ? All details on this will be helpful.
Also, what do you think about the RDPs ? Don't know if renting RDP is cheaper or expensive but it can also serve the purpose if one is not so comfortable with the VPN and the privacy is fool proof when you use a remote RDP. Isn't ?
It isn't. RDP is a protocol for remotely accessing a server, while a VPN is used to encrypt all data transmitted over a network.
As for VPS, you can rent a server from any convenient site. This can be such popular sites as AWS, Azure, GCP, Digitalocean, as well as many other hosting providers.
By the way, the Digitalocean site has a detailed
tutorial on how to deploy OpenVPN. But if you don't want to go into all the intricacies of VPN configuration, you can set up a VPN server with the help of such a program as Outline.
