LiquidCore.RO, I-Ware and Quanta SRL announces that our custom new server, the second one, runs the latest release of your great linux distro, CentOS 5.3.

The main job for the server is to deliver websites, galleries and forums, mostly based on Joomla and phpBB, the e-mails with Postfix & Dovecot etc, but also to offer web hosting to our friends and a few clients. We use Webmin, Usermin and Virtualmin PRO as the access, management and hosting panels. It also stands for a DNS, file and FTP server. It is not a big business but rather a personal and a non-profit one to bring the latest news, reviews, benchmarks, "how to"s in games, hardware and software to the romanian enthusiastic community.

Thank you CentOS!

We saved one of our clients thousands of dollars migrating file servers from a Windows File server environment to a Samba Centos Server. In fact, during the last virus scare our client called us worried about the so called April Fools virus. We told them not to worry that their File Server was protected due to it being on CentOS. :) Got to love Linux! especially CentOS!! :)

We recently migrated our last windows server! We were using microsoft Exchange 2003. We had to stay on the Windows Server because of our dependency of Blackberry devices. Fortunately we found a fantastic mail server called Kerio and ported into CentOS 5.2 and we have never looked back. In fact we found our new Linux Mail Server could handle thousands of emails at a lower CPU and memory. Our migration was so successful on CentOS and Kerio we decided to become resellers of the product.

Hi, just want to say a big thank you to the CentOS team for providing such a superb enterprise operating system. We've been using CentOS for several years and it's never let us down.

We use CentOS5 at White Horse Creative for development work based on the Drupal CMS. The combination of stability and performance is great. And it just works. For those reasons, there really is no other choice for us.

Our development machine:

Supermicro motherboard
Quad Core Intel CPU
8 GB OCZ RAM
1 500GB Western Digital SATA
1 RAID0 array w/ 2 Atlas 10K Maxtors
on an LSI controler

The heavier duty apps this machine runs are as follows:

IPTABLES gateway
SQUID reverse caching proxy
APACHE webserver
PHP
MYSQL
NFS
BAZAAR version management


The most important thing to us is stability. But we also need performance. Out of the box CentOS gives us both whether it's our primary development server or laptops. Of course we've seen benefits tuning to our specific workloads. But that is just icing on the cake. Thanks so much CentOS.

Seval Data has started this week another server, running Centos 5.2. Our plan is to start another server on this year, so let's hope to do it!
We're very satisfied with CentOS. It's a stable operating system.

Wemoto On-Line Motorcycle Parts Retailer have been using CentOS for our PostgreSQL database servers, Apache web servers and Sendmail mail servers for the past year and are extremely satisfied with the results. Our hardware includes IBM x3655 twin processor dual core AMD Opterons, generic AMD dual core x86_64 Althlons and HP Proliant quad core Xeon systems, CentOS loaded and runs faultlessly on all of them. We certainly recommend CentOS as a robust operating system for any application.
