This is an essay I wrote for the course IT Management. The task was to write an essay about one of five given topics. The topic I chose was cloud computing. 

Abstract

In the past decades, there has been an explosion in terms of available computer resources. Smaller, cheaper, faster, robust, and scalable computer systems. Virtualization and cloud were a few years ago – and still is some of the most popular buzzwords in IT. It opened a completely new dimension for the computer industry. Instead of investing in a large data center that was used only an hour a day, the computer resources could instead be hired from a cloud vendor such as Amazon or Microsoft. Although many techies says the cloud is the solution to everything, there are several risks and challenges when it comes to exploiting the great advantages of the cloud. In this essay, I will mainly discuss challenges around using PaaS (Platform as a Service). In addition, I will also discuss cases where PaaS would be an excellent choice for an application instead of running the application on premise.

When I was a kid, my favorite game on my GameBoy Advanced was Megaman NT Warrior. I did not see any reason to get any other game for by GameBoy as I felt Megaman was much more awesome than both Pokemon and Super Mario. The plot of this game was to switch between the real world and the virtual world and save the world from a criminal organization called WWW (World Three). WWW took over computer systems and planted viruses in the computer networks. WWW had a vision of taking over the world. I had to enter these networks and delete these viruses. In this game, the networks were a virtual world where I navigated with my net-navigator Megaman, which I used to delete viruses with by using different weapons (Activated by using battleships). Outside these networks, Megaman was on a hand-held device called PET (Personal Terminal). This powerful device would let me read emails, interact with my net-navi and contact other people.
