Hi All,
I am new to this forum. I am an application admin on Windows and Linux. So not new to Linux but only looking into application part.
However from past few days i was planning to change my career totally inclined towards Linux. So thought to go for RHCE. Read a lot about it and planning to do in next six months. Hope everything works as planned. Thanks to all for some genuine suggestion.

One Imp thing i have been hearing a lot abt cloud computing and it seems companies pumping lots of money in it. So it is going to be the future. Also i read on RH site Red hat is going to be key players in the market.

Could somebody tell me what exactly is this cloud ( i only have visual picture but no idea abt the ground realities)
- How do we fit in the new cloud model?
- Do my RHCE or RHCA in long run going to benifit me? or things will get obsolete till the time we get these certs.

cheers

"Cloud" basically just means you don't write your applications for a specific machine or location. They are written with some general-purpose code, then you allocate a unit of processing power (usually a virtual machine) from a rack of computers. You don't need to know or care where the computers actually are. If you need more power, the cloud management application assigns more CPU / storage resources to your app. Then when it is done running, those resources can be allocated elsewhere.

I did a quick search, and maybe this will help explain it:

Welcome to LQ.
On your first part: http://en.wikipedia.org/wiki/Cloud_computing
RHCE and RHCA are advanced certifications. But RHCE will only help you get your resume noticed. Nothing more. You will need to prove yourself for that. And experience is what will teach you everything. It will also depend where your interests are. Linux or windows? Are you wanting to migrate into Linux just for the sake of job? Dont do that. Be with windows. Or are you really looking forward into Linux? Something like passion that drives you?
Cloud computing in itself can not be a technology but a methodology. And yes its going to be big. Most of the companies are looking into it. Amazon, IBM and Google are already into it.
