Virtual Love

Man, I am falling in love with virtual machines, more and more. I have had the opportunity to work with virtual machines at work recently. Unfortunately, the project is already a little late. Otherwise, I would have taken the opportunity to experiment with different virtualisation solutions. So, I stuck with what I knew and managed to get the systems up and running in record time. Virtualisation is really a life-saver.

I have been having trouble getting Tomcat running on a virtual machine after trying for half a day. Finally, I gave up and decided to start over. It took me a few seconds to wipe out the old virtual machine and create a new one. Then, it took me a matter of minutes to get Tomcat running on the new virtual machine. I am still not quite sure what went wrong with the first install but since it was my first time working in a CentOS environment, there was a lot of experimenting going on and I might have done something wrong.

Oh yes, having a virtualisation environment allows me to play around with different flavours of Linux as well. It has been ages since I played around with a RedHat related system such as CentOS. So, I got to play around with yum in the last couple of days. I have to say that I prefer the debian apt system better. It resolves and retrieves packages much faster than the yum system. I am not trying to open a can of worms here but that is what I had observed.

I think that once I have a little more free time, I may actually experiment with some other distros. The project that I have been working on is currently late by several months. So, I have to stick with what I know and use my past experiences and existing knowledge to get things up to speed first.

PS: I am right to hate Java. It is impossible to run Tomcat with a limited amount of RAM. Java just drops out with an OOM exception.
