Web Hosting Configuration

[radu_s2003]

Hello,

I want to make my own web hosting company, so I will buy some second-hand servers and routers, switches, ups (HP servers with 2,2GHz, 2-4GB DDR1-2, HDD 250-500GB with Raid5, Gigabit NIC`s, routers, switches from CISCO).

I want to know if you have comments on this, maybe suggestions, other configuration, etc:

OS I will use CentOS

- SRV-FRW (intern)- Firewall+VPN

- SRV01-WEB (4clients)- Apache2+JRE+PHP5+FTP+SNMP+Antivirus(Clam)+PHPMyAdm in+Cpannel
- SRV02-WEB (4clients)- Apache2+JRE+PHP5+FTP+SNMP+Antivirus(Clam)+PHPMyAdm in+Cpannel
- SRV03-SQL (4clients)- MySQL+SNMP

- SRV04-EML (email-4clients)- Email(Zimbra)+Mysql+JRE+SNMP

- SRV05-INT (internal+ticketing 4clients)- Apache2+PHP5+MySQL+Cacti+Ticketing(GLPI)+SNMP+Tomc at6+JDK+Samba+Alfresco+WebKeepass

- SRV06-ESX (4clients)- Vmware ESX+SNMP


On the SRV-FRW will be an firewall and VPN, maybe BGP, here will enter 2 ISP, with different switch for all infrastructure (ISP1 for servers 1, 2, 3, 4 and ISP2 for servers 5, 6).

If ISP1/2 is down, the SRV-FRW must to grant access to all the infrastructure from the ISP that is UP.

I will have minimum 2 Gigabit NIC on each server and 2 Gigabit switches.


I will need some advice about one automation when the clients pay to automate generate the accounts, and another automation to remember to users when the pay is coming soon. (Maybe for the last one will be one CRM).


So, in the and, how do I make the SRV-FRW to do the Switch from ISP1-ISP2 and how to make that`s 2 automations?
Others propose for an webhosting?
The OS is ok?
