The better OS Architecture

Hi ...

I need to install few linux vms (VMware and KVM), and I am looking to know what would be the better OS architecture to choose from:
32-bit or 64-bit.
If you may, please, suggest  white papers as references would be highly appreciated.  

Thank you for your help.

If you need to use lots of memory in the VM, then 64 bit, otherwise 32 bit.

Have you considered using Docker ?
64bit can run all 32bit applications

Thanks Andrew for your comment.
In terms of hardware resources usage, that is making better use of available CPU, Memory, ... When I install 64-bit OS on a system with 4GB memory comparing to 32-bit OS, the rate of "Windows Experience Index" is better. Example; actual usable memory is higher

I started reading/learning about Docker using a online resource while ago, but was not able to continue and complete it.
I don't think there is much point in installing 32 bit OS anymore.. - legacy!
In all that is possible use 64 bit if you ever intend on using more memory

Thanks Fred.
Actually, i am looking for some solid facts here, rather than, just "do not install 32-bit...", that you have mentined them.
I am trying to migrate to 64-bit from 32-bit OS, but some of the developers are not in my favor. So, i need to provide a solid data,statistics,..etc  as how we can benefit from this migration and so far You have given me some out of other comments. ;)

fred hakim: thank you for numerology, as with all numerology some stuff went foul, in real life:
32bit Linux supports 64MBytes of RAM via PAE (i.e ppro and above)
uClinux (32/16 bit) also supports 64bit timers and 32bit uids/gids

...For what?

There's only very rarely a way to determine if anything is "better" or "best" without appropriate context. You mention "some of" your developers, but no mention of what they're developing nor how many developers are involved in total and what "some of" means nor if there are actual reasons given by "some" that have an impact on the decision.

What is developed? Who are the product customers? What hardware platforms is the software to run on? Other questions might follow, but at least we can have a starting point.
I am surprised how completely technically unfounded BS got accepted as a solution.
Cool Gheist, s*** happens lol
