On Friday, September 10th, I attended VMWare Customer Day 2010 Korea, which was held at COEX Intercontinental Hotel, Seoul. Even though it has been a while past the event, I would like to share some notes worth sharing, combined with my personal thought about substantial content found in the talks I listened to during the event.
As the event title suggests, the talks mostly covered introductory concept about cloud computing and virtualization as well as some promotional materials about VMWare products.

The second and third session were presented in Korean so I only grabbed the general understanding and did not really grasp the details.

He also explained key drivers and phases toward its adoption in the enterprises and an era of IT as a service powered by the cloud. He started with listing several IT challenges in the enterprise environment.
