Good afternoon !

I want to transfer the site to CMS Wordpress, to a new hosting Hetzner Cloud, tell me please, I will be very grateful:

1) Difference between Location - Nuremberg DC3 and Falkenstein DC8?
2) What is Type LOCAL STORAGE (NVME SSD) and NETWORK STORAGE (CEPH)
3) Additional features - User Data what is it?
4) What is the SSH key for?

Is there an explanatory manual in Russian on the network for setting up Hetzner Coud, please share the link.

Thank you for your attention !

Answer 1

1. The difference in the geographical location of the data center.
2. Obviously LOCAL STORAGE (NVME SSD) is a solid state drive in the server, and NETWORK STORAGE (CEPH) is network storage. The first is much faster.
4. To connect to SSH with a key instead of a password. Anticipating the question "why not connect with a password", because the password "SuperHacker92" is much easier to crack than the RSA1024 key.

Answer 2

1. Different data centers in different cities.
2, 3: https://wiki.hetzner.de/index.php/CloudServer/ru
4. Authentication with a key instead of a password. The password is an extremely inconvenient way.
