We are very early stage IoT and Analytics company [not in hosting business], after working with nice good hosts [netcup, hetzner] VPS systems, now we are moving some server into co-locations in India.
We bought used servers, setting up and testing them for clusters LXD at this moment. This is our first time experience handling barebones and co-location.
Do we need firewall for Data Center or manage with Linux Ubuntu firewall?
We will have a switch for internal networking.
Data Center has redundant power supply.
Got quotation for 1 kVA, we have 4 x server + 1 switch, If I understand some math, it can handle 800 Watts.
Is there any checklist for co-location?
