How to administer many servers?

Question

System administration

There are several dozens of servers (both physical and virtual machines) at our disposal, 2 are running under Windows Server 2012, the rest under Linux.
What useful tools can you recommend for administration? In particular, I would like to be able to execute remote commands, restart services and other routine actions through the web face, without going to each server via ssh/rdp.

Answer 1

chef, puppet, ansible, salt
if something is one-time, then fabric can

Answer 2

ansible

Answer 3

For *nix: chef, puppet, ansible, salt as already mentioned
For Windows - powershell, group policies, domain (but not for two, of course).

Answer 4

Ansible, they also saw it under Windows, it works fine under Linux. Well, or Salt. Chef and Puppet are first-generation systems, so to speak, they are more difficult to deal with than with ansible and salt.

Answer 5

Well I do not know. I have > 100 servers and the number is gradually growing.
Zabbix monitors all this goodness, bash scripts and one python script are enough for some settings, if you need to massively send the necessary files to new wheelbarrows and add authorization by key.

Answer 6

Remote Desktop manager free
Under Windows itself, at least rdp, at least ssh, everything from one window!
