Question

Virtualization

Hello dear community.

Help me decide whether to virtualize for the sake of 2 services on one hardware platform for a small company of 25-30 people.

We have 1 Dell PowerEdge T110 server; Tower; Intel Xeon Quad Core X3470 2.93Ghz cache 8MB FSB 1333MHz; RAM 4x2048MB PC3-10600 DDR3 SDRAM; HDD 4x500 Gb 7,2K rpm 3.5" SATA; Required

:

1 Microsoft Active Directory Services + fileshare + Bases 1C Bukh and Consultant Plus
2 service Firewall / router with multiwan support, VPN tunnels and beautiful statistics of Internet use by employees.

There are several options :

A: Install Hyper-V Server 2012 on the server and raise 2 virtual machines with Windows Server (AD, balls and the rest) and Kerio Control Hyper-V Virtual Appliance (ITU / router / VPN)

or

B: Install Windows Server on physical. server + buy a second server for Kerio Control

and another option

C: Install Windows Server on physical. server + buy Ideco or some iron solution (and which one?)

Answer 1

DBMS virtualization is a bad idea in general.

Answer 2

Option A for a small office is quite efficient. It, of course, is not the best practice - to combine an AD controller and other services (and not have a second controller), but it works.
I had a specific experience of deployment and support on one piece of hardware for an office of 15 people ESXi 5.1 with three virtual machines - 1) Windows + AD + Exchange + 1C + fileshare; 2) PFSense software router; 3) Elastix VoIP telephony.

Answer 3

Put on a physical service, as a linux / unix-like os gateway behind the eyes, we can also integrate into hell if necessary, for such a small office it is not cost-effective to wind up virtualization in my opinion.
at the beginning of my career there was an office where I headed the department, xen was used as virtualization, 1C, hell and others got along quite lively, though I had a gateway on freebsd
