With clouds (private and public) where you spin up new VMs or containers for
every deploy, how do you guys deal with:
Login in:
- Can you ssh to all your servers/containers? Or just check centralised logs?
- If you can't ssh to them, how do you solve hard problems, problems where
you'd traditionally use netstat, iostat, strace etc...?
DNS:
- Do you servers/containers register themselves on a DNS server?
- What about containers sharing their server's ip? How do you access them
individually?
Authentication:
- in this new world, do you create one userid per staff, or everybody's
using the same one?
- if the latter, how do you deal with finding out who did what? What about
audit/reporting requirements?
- if the former, specifically in public clouds, what auth mechanism do you
use? Do you setup your own NIS/samba/AD server in the cloud?
Thanks.
