Hosting suggestion for network area

[elliott]

Greetings. After conducting research for a long time and completing an internship in this field (2 years ago), I am planning to establish a business in the Network sector. Where can I host the server I will acquire, which features a Threadripper processor? What is the current status of symmetrical line bills? How much are hosting fees? Which firewall is recommended?

I kindly request friends who have the answers to my questions to please leave a comment on the topic.
