It is better to rent a VDS since it has protection against Ddos attacks and ordering hosting management will personally solve problems with attacks.
Own VPN
Many users currently use a VPN because they want to circumvent restrictions or for other reasons. And companies, in turn, will benefit from using their own VPN to provide access to remote employees.
It is very convenient to provide access to the workspace through your VPN. Because without it you will not be able to connect.
From personal experience, I can say that this country email list type of connection to the workspace is very effective. No one will be able to connect to your server on which the work will take place, as well as a VPN created on VDS will deter Ddos attacks and clearly slow down hackers.
Currently, there are bots in every telegram/discord channel that help users. The creators of these bots make a profit for their use and you can also do it.
To do this, it will be enough to come up with a unique bot and have programming skills to write code. However, in order for your bot to work constantly and be able to help users, it must be placed on the server. VPS is best suited for this because of the hourly rate. Many bot creators use VPS servers, which is why they get a stable profit.
