What ISP do you have?  What Internet plan?


I assume your NextCloud is running on a virtual private server (VPS). 
Which provider and what plan?  How many users are connected when CPU 
cycles run out?  What about memory?  Storage?  Network I/O?


What about the other services?  CPU cycles?  Memory?  Storage?  Network I/O?


Are you thinking one machine with all services running on one hardware 
OS instance?  Jails?  Virtualization?
