Cisco and VMware Submitted VXLAN for Open standard

Posted on September 2nd, 2011 in Announcement, Data Center, vCloud, Virtualization | No Comments »

Interesting announcement from Cisco and VMware during the VMworld 2011 which was regarding the VXLAN capability. Both company had invited a group of product principle together to submit the VXLAN to IETF for approval as a standard for future.

Let’s talk a little bit more about what is VXLAN and why do we need that. As of today, DR solution are commonly deploy by every enterprise environment. Did you realize 1 of the biggest challenge which always happen on the DNS record, hard coded IP segment, subnet and VLAN which always require human interaction to manually change it, to allow a success fail over of the DR scenario? Well, I think this is just 1 of the major issue commonly face. With Cisco Nexus 7000 come with OTV (Overlay Transport Virtualization) which allow you to stretch the Layer 2 traffic over Layer 3, with minimal bandwidth requirement. Cisco had done a great job to the enterprise to address this, which now you can have both side learning the same VLAN, Subnet and ip address. A DNS and ip changes is no longer require as both end are transparent with similar VLAN.

VMworld 2011 had focused a lot on private and hybrid cloud computing environment which address the concerns from enterprise over the public cloud offering in the market today. One of the key highlight during the event was the new capability over vCloud director version 1.5.

With vCD 1.5, you can now manage both private and public as a hybrid mode from the administration with secure federated. It allow you to subscribe, manage, relocate and provision anywhere you prefer, could be internal infrastructure or public cloud provider you choosen and manage in same console.

Network Consideration in Virtualization and Cloud Computing

Posted on December 3rd, 2010 in Data Center, Server, Tips, vCloud, Virtualization, vSphere | No Comments »

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.
