Take for example i have 4 servers A,B,C,D. All are on same network and all have same services running like Apache, Tomcat etc and when patching is required to be done on these servers i need to stop, Start these services. Right now i am manually going into all the servers and doing the same. I know SSH can be done here but i am looking for a script which i when click gives me options:

Which server i want to go in.
Once i get in for example server C. Script should automatically ask which service u want to Stop? I am hoping we can declare these services with path in the script.
Once stopped it should display a message that this particular service is stopped.
It should not stop here, it needs to go on as i might or i have to stop other services on other server..
And then there should be something to start them.
Need to do this sitting on a single server. In my prod. environment i have 25 servers it is a pain for me to jump in every server or even doing SSH all the time. I know there can be script written and might be a long one.

PS: I cannot use and install Ansible.

This might give you a starting point. Note there is no sanity-checking done here:

#!/usr/local/bin/bash
# example invocations:
# script.sh - prompt for everything
# script.sh a.example.com - prompt for service and action
# script.sh a.example.com smbd - prompt for action
# script.sh a.example.com smbd restart - prompt for nothing

hosts=(a.example.com b.example.com c.example.com)
services=(apache2 mysql smbd)
actions=(stop start restart)

if [[ 3 -eq $# ]]; then
 ssh "$1" "sudo service $2 $3"
 exit $?

 select action in "$actions[@]" "Quit"; do
