Even if you do not use their services, you might find it useful to 
emulate them and implement a private cloud.

Please specify the architecture of your services, your current 
development/ test/ staging/ production infrastructure and facilities, 
your current workload for each service, your current quality of service 
for each service, and all other relevant details.


Please describe your goals for the new data center in terms of the above.


Please specify your budget and schedule.

I suspect they see no financial benefit in doing so.

Business owners are usually interested in spending their money on things 
that provide a positive "return on investment".

Please define "enterprise context".  (I would define it as thousands of 
employees and even more web hits and e-mail messages per day)


I view Debian as the dominant enthusiast Linux distribution in the USA. 
I use it on my SOHO laptops and desktops because it mostly works on most 
x86/x86_64 computers made in the last ~20 years.  (But, it is common for 
the "stable" version not to work on recently designed hardware.)  I also 
have a Ubiquitti Networks Unifi Controller application stack running on 
a Debian VPS on the Internet ($5/month).  I am the only user and it has 
never failed.  Other people with far more knowledge, skills, and 
ambition do more with Debian, but the effort appears to be both heroic 
and lonely.  I have yet to hear of an "enterprise" environment built on 
Debian, but you can tell us about yours when you build it. (URL's for 
examples of such are welcome.)


I view FreeBSD as the dominant free x86/x86_64 BSD/Unix server 
distribution.  I use it on my SOHO servers because the design is 
traditional, the feel is polished, software packages are recent, and 
there are good books available [1, 2].  FreeBSD has notable enterprise 
deployments and commercial derivatives [3].


I view Ubuntu as the dominant commercial Debian derivative company, Red 
Hat as the dominant USA commercial Linux company, SUSE as the dominant 
German commercial Linux company, and Oracle as the dominant commercial 
Unix company.  If I ran an enterprise data center on Unix or Unix-like 
computers, I would find the following characteristics of these 
commercial offerings to be very appealing:

1.  Configuration management, quality assurance, and documentation.

2.  Hardware and software certification/ integration (notably Oracle).

3.  Technical support and consulting.

4.  Personnel training and certification.

If you use a commercial OS, certified hardware, and certified software, 
you should never experience compatibility issues.  If you do find an 
issue, you make the vendor fix it (or fire them and hire another vendor).

I have a Dell PowerEdge T30 and do not recall any issues with Debian 9. 
(But the fact that Dell disabled the M.2 NVMe port in the firmware does 
irritate me.)


I have had good luck with Antec cases; Thermaltake power supplies, Intel 
motherboards, network interfaces, and solid-state drives; and Seagate 
hard disk drives.


> Note: I will need some RAID solution hard or soft.

"Enterprise" implies storage area networks.  This requires hardware (and 
support software).


Drives and/or racks with dual interfaces require hardware (and support 
software).


Hardware RAID (and support software) should give you the best I/O 
performance and least CPU load, but implies locking you into the 
vendor's way of doing things.


Software RAID gives you the most control and flexibility, but impacts 
I/O performance and CPU load.

Your English is fine.

You're welcome.  :-)
