There is an interesting article provided by Vyatta about the most common mistakes practised by many companies, and I think that from this white paper we all can get something beside server virtualizaion, and should conside give network virtualization a try in the near future. You can get the withe paper here.
The Top Five Virtualization Mistakes
MISTAKE #1: LEAVING THE NETWORK UNSEGMENTED
MISTAKE #2: VIRTUALIZING ONLY THE SERVERS
MISTAKE #3: FORGETTING TO VIRTUALIZE THE BRANCH OFFICE
MISTAKE #4: FORGETTING TO VIRTUALIZE THE NETWORK AS PART OF THE DISASTER RECOVERY PLAN
MISTAKE #5: FORGETTING TO SELL YOUR OLD HARDWARE ON EBAY
The conclusion:
To get the most out of your virtualization project and to avoid common mistakes, here’s a checklist to use in planning.
1. Look for unsegmented networks that might be at risk from virtualization and use virtualization tools to segment them.
2. Look at the networking functions associated with servers you plan to virtualize and virtualize them together.
3. Consider networking functions such as routing, firewalls, and VPN as part of branch virtualization projects. Putting them on the same hardware as other applications will get you a long way toward “branch in a box.”
4. Use virtualize to include network functions in disaster recovery plans, so that when there’s a disaster, your routing, firewall, and VPN will come back online along with the rest of your compute resources.
5. Sell off specialized network hardware on eBay. By using x86 hardware and virtualization, you’ll save money on purchase, operation, and maintenance.
