Parallel execution on multiple servers in UNIX

I have a requirement (in a shell script) to connect to several servers at once and execute a series of commands.

I am aware that ssh can be used for sequential execution. But since most of the commands that I need to execute take a long time, I have to go for the parallel option.

Is there a way to run commands simultaneously without using any command line tools such as pssh, cluster ssh etc?

Can someone please help?

Did you consider executing the ssh sessions in background?
