Cloud Computing Goes Far Beyond Virtualization

Virtualization vs. private cloud has confused many IT pros. Are they the same? Or different? In what way and how? We have already virtualized most of my computing resources, is a private cloud still relevant to us? This 2-part series is to answer these quesstions. Lately, many IT shops have introduced virtualization into existing computing environmentw. Consolidating servers, mimicking production environment, virtualizing test networks, securing resources with honey pots, adding disaster recovery options, etc. are just a few applications of employing virtualization. Some also run highly virtualized IT with automation provided by system management solutions. I imagine many IT pros recognize the benefits of virtualization including better utilization of servers, associated savings by reducing the physical footprint, etc. Now we are moving into a cloud era, the question then becomes "Is virtualization the same with a private cloud?" or "We are already running a highly virtualized computing today, do we still need a private cloud?" The answers to these questions should always start with "What business problems are you trying to address?" Then assess if a private cloud solution can fundamentally solve the problem, or perhaps virtualization is sufficient. This is of course assuming there is a clear understanding of what is virtualization and what is a private cloud. This point is that virtualization and cloud computing are not the same. They address IT challenges in different dimensions and operated in different scopes with different levels of impact on a business.
