EUCALYPTUS — Elastic Utility Computing Architecture for Linking Your Programs To Useful Systems — is an open-source software infrastructure for implementing Elastic/Utility/Cloud computing using computing clusters and/or workstation farms. The current interface to EUCALYPTUS is interface-compatible with Amazon.com’s EC2 (arguably the most commercially successful Cloud computing service), but the infrastructure is designed to be modified and extended so that multiple client-side interfaces can be supported. In addition, EUCALYPTUS is implemented using commonly-available Linux tools and basic web service technology making it easy to install and maintain. For more information click here.

After I got the job as Server Administrator, the company server were running on Ubuntu Servers. So for the last 6 months I am using ubuntu. And there is not much differences in the file system. Only some differences in some command for example we use ‘yum’ command to install any thing in fedora and ‘apt-get, ‘aptitude’ command to install any thing in Ubuntu.I did’nt find any big difficulties in using Ubuntu, ofcource there are lots of help if we go online. Last two weeks back I installed Ubuntu 8.04 in my laptop, it is quite good.

Last week I got an iso image of OpenSolaris and I installed OpenSolaris in the VMWare virtual machine. Solaris is one of the best OSin the world and it is stable. First I installed apache, mysql and PHP in the Solaris machine. I used the command ‘pkg-get’ to install these packages. In Fedora and Ubuntu the configuration files of installed pakages where stored in the location /etc/. But for OpenSolaris the configuration files where stored in the location /opt/csf/etc.
