Yes, your Puppet Master can be an Agent, it just talks to itself. Most
people manage Puppet Agent and Master configuration with Puppet itself -
get it to manage it's own config and restart itself when it changes.
This means you only need a bunch of text files - your modules and
manifests - to rebuild your entire infrastructure.

Thanks guys that was really very helpful and did clear lots of
concepts in my mind for puppet. Absolutely brilliant that means that
with collective I can even launch the instances on EC2 aswel and can
even run the required services on demand within the boxs.
One thing I also like to know say puppet master connected to 20 boxs
in a cluster and all the agents are connected to master and are
running in daemon mode and doing well,but if i need to do some
changes or update few things in an admin box itself (i.e Box with
puppet master) so how do i do that? do i need to install puppet
client aswel where puppet master is running to do the required job or
puppet master can be use to configure itself? If yes then how.

Overdue,
Walter is right in that you will need to look to another tool,
such as MCollective. Puppet is not the best at orchestrating
operations across multiple servers. It can reacting to things on
one machine, like an Apache servers' config file updating, but
there's nothing in core Puppet that's going to have your Varnish
servers react to this event.
MCollective is a job scheduling frame work that can do what you're
after and integrates with Puppet quite well. Other products are
Func and RunDeck.

at mcollective. It allows you to define a set of servers that

to do a puppet run on.

I am sorry if my message annoys you or if its a bit
childish please

should ask,
My Question is :
I have a server running puppet Master and 8 clients are
connected with
Master and every half an hour clients pulls up there
configuration if
requires from master and update themselves, but if need to
restart
Apache on 4 of them and have to restart varnish in the
remaining 4 all
in a sudden then how i will do that? do I need to wait for
the next
half an hour that clients connects with master and restart
the service
or is there any other way for doing so?
