CentOS Rocks Good-Bye RHEL

Home Data Center saga

I upgraded my home “data center” recently with the addition of two used HP DL320s.  They both have 4GB of RAM and two 15k 36GB drives in a RAID1 configuration.  I build and buy hardware as a hobby to keep me close to the reality of managing corporate software systems and data centers.

From RHEL to CentOS

I decided to run CentOS 5.2 on these new home systems.  It is fantastic.  You have to love the GPL that makes this possible.  Some companies making their first foray into Linux might not feel comfortable using CentOS.  Mature companies that have been using some form of RHEL for a few years should feel very comfortable.  How many Linux OS support calls do you make in a year anyway?  Needless to say, we are migrating AOL from RHEL to CentOS at a significant annual savings.

I would have gone to Debian, as I needed a free alternative  to improve my company’s operating margins, but why not use CentOS when it is binary compatible with RHEL and FREE?  Easy decision.

Open Source Commoditization of Software

Similar to my decisions to move my previous companies off of BEA WebLogic to Tomcat and Sybase to MySQL.  It is almost hard to believe that companies payed for the Netscape Web Server now that Apache is ubiquitous.  Distant memories of companies paying for Alta Vista, Verity, or FAST search products now with Lucene and SOLR.  Thank you Open Source!

Home Data Center “Drudgery”

Managing my home data center takes more time lately. I now have a mac mini and a Fedora Core 3 box in my office.  This is in addition to the servers in my garage.

I enjoy the Fedora Core 3 box and am looking to upgrade an older AS2.1 box to Fedora.  First I need to  move the old applications off of it. I am keeping notes in a Wiki on one of my machines now to track all the stuff I am doing to these boxes. At least I have MRTG graphs for my PIX and my NICs on all the machines in the garage. I also have RRD graphs for all of the web servers on those machines as well.

Connecting my DSL and Cable Modem Networks

I plan on buying a PIX for the upstairs office.  This way I can make a site-to-site VPN that auto connects between the upstairs cable modem and the garage’s DSL line. Then I will instrument the upstairs machines with MRTG and RRD as well.

Maybe I will start my Harley some time in May. It has been so long the battery may be dead by now. 🙁 It is overcast and cold this morning up here in the hills – so no ride today.
