Why it's better to rent a server than buy one
You will not need to maintain the equipment: no need to worry about uninterrupted power supply, fire safety, limitation of access to the server.
When you need to increase the technical parameters, you simply replace the rented server with another one, instead of buying a new one.
When renting, you get access to the equipment within 24 hours without worrying about communication channels and Internet connection. If you have any questions or need help with the server, you can always contact the 24/7 support team.
