Hi guys, i find this forum really helpful. I did post a thread about technical writing. I am designing a small system for a debt collection company and here is my analysis. If there is any opinions then please do reply.

I spoke with my client and they require a server which is flexible enough to migrate when their data increases. So , they want to start a small scale and then move to a medium in future. Since the company has a small budget, i am going to recommend cent os. Moreover, I have thought of building a single server and run all the services in it which includes web, database, dns, dhcp, samba etc. The other way round is that i can run multiple KVM which would obviously require a high end machine.

Either would work.

Just remember to securely back up the data somewhere else. Like a cron job that encrypts files and uploads them to Amazon S3, or something.

As above, for a business server Centos is fine (free RHEL).
As well as regular backups, I'd also recommend some kind of RAID eg RAID1 / mirroring.
Most backup tools are really just for apps/data. To backup the entire OS, try Clonezilla or MondoRescue.

Given the app (debt collection company) I'd aim for a fair amt of security eg https/ssl/tls for Apache, Admin etc via ssh and uploads/downloads via scp/sftp, setup iptables etc, you know the drill ...
The free tool Filezilla is a nice GUI for sftp and runs on MS clients.

Hi guys.I just talked to my client and he is wants to host asp website in the web server which is running cent os(linux).
I think they might use MySql as the database which is not a problem for me but the problem relies on .net frame work.
I did some research and came up with "mod_aspdotnet". Does anyone has quite an experience with such circumstances. Please let me know.
Cheers

I'd echo the previous comments about making sure the server is using RAID, and preferable a "real" server and not some biege tower bought from a local PC shop. As for backup, I'd take a daily backup of the database as a dump to the physical server and then throw the whole lot on to tape each night with a minimum of nine rotations (Mon-Fri + 4 rotated Weekends)
