Week 7 Clear: Software in Flux

This week's material was so jam packed full of good stuff it is hard to contain and will probably be hard to retain! We began with Open Source Software (OSS) and learned about the many types, the benefits, and the essentials. It appears that there are so many benefits to using OSS such as: great quality, high reliability, great flexibility, low associated costs, and an end to predatory vendor lock in. Also the access to the source code gives it a great advantage over commercial software as there is the ability to fix bugs yourself, modify behavior of the program, and add features.

Here is a brief history of Open Source Software!

The Economics of Open Source Software
Learning how companies can afford to distribute this type of software was very interesting. I have used open source software applications in the past where they were given to me for free. Though most of the applications I got my hands on were of lower quality and I have not really kept using. But they were free, I now know why, as the companies either take donations (smaller companies that have this type of software for use) or they charge for support, which can get very pricey.

The Cloud
Another topic that was pretty clear to me was somewhat new to me, at least most of it was. When the new iPhone 4s came out, it was all about the "Cloud" and I was like what is this cloud stuff they are talking about? Is this something new? But after reading this material and watching the lectures I just found out it was basically the Internet, in a way. Personal cloud based computing, such as, Gmail, YouTube, and Spider Oak are just a few examples of this type of computing. So many of the services we currently use are cloud based and most of us don't really know it, or pay attention to it. Enterprise cloud based computing now, is a little different, there are monthly subscriptions, they are highly scalable, and you can write your own.

Cloud computing options seem infinite and are the way of the future, as it frees up disk space on your physical machines and is ever evolving. It also frees up IT staff and costs to focus your resources.

Virtualization
I can't lie...this week wasn't all clear! When it came to virtualization, it was like I got hit in the head and was left dazed and confused. It actually started out very confusing, but as I went on in the lectures and reading, it started to become more clear, though I know I am not ready to jump in to try doing this on any of machines at this time and probably not in the near future either.
