Adoption to both virtualization and cloud computing, network become the important component of the success to both solutions. For many of the mature deployment and operation in virtualization, network become the uncontrolled piece in the virtual infrastructure which allow administrator to breech the change control management from the production network without proper authority from the network administrators. Some of you may not been agreed with this statement but it does impact the production environment.

The traditional vswitch or dvswitch did not provide control, manage as the physical switching environment in the data center. It allow administrator to provision new virtual machine and connect to network without proper request and change management in place. Let’s imagine, the effect will be the same as unauthorized persons connected a server to the production LAN without a change approval. In physical environment, we can shut off all the unused network ports in data center, in virtual, you will not able to perform this while using vswitch or dvswitch from vmware. Technology limitation for the past previous years does not allow network operation to be fully integrated until the Nexus 1000V from cisco & VMware join develop products come to place. This will allow administrator to manage and control the access level on the virtual environment as it does in physical switch. Transparency and Manageability is possible on virtual layer now.  Network performance analysis and troubleshooting become easier compare to previous.

vCloud director come to place to provide private & public cloud to enterprise. Many of the new features are great and useful to the cloud environment. Introducing virtual firewall, security control and others function in vcloud director, does help to improve the cloud infrastructure, but should this fall under the vmadmin , network admin or security admin roles? Users may need to reconsider the approach by introducing all this new technologies to the production environment. They may need to get the right expertise and team to manage each different functional. This will allow the IT organization to move forward together without breaching the rules & regulation been set in the infrastructure.
