In-Flight Upgrades

I think that all the required technology is already in place to support in-flight upgrades. Here are some examples of what I mean:

Air Travel

You board an airplane. Three minutes before the plane pushes away from the gate, a computerized announcement airs: “There are four unsold seats in first class. Bidding for these seats is now open. Please use the touch screen in the seatback in front of you, along with your credit or debit card, to place a bid.” 90 seconds later: “Bidding has now completed. The passengers in seats 7D, 14A, 3C, and 12A may take their seats in first class.”

The computerized bidding system would simply choose the highest bidder(s).

Shipping

You purchase something that is shipped to you. Initially, you choose the slow-boat shipping. A day or two later, your eagerness to have this item increases. So, you go to the shipper’s tracking site, enter the tracking number, and click Upgrade Delivery Time. After keying in your credit card digits, your package is expedited so that it arrives faster.

I don’t know much about the inner workings of shipping companies, but it seems to me that packages get handled at least every 24 hours during transit. If that is true, there should be ample opportunity to upgrade an in-transit package to a faster delivery service.

I bet shipping companies could get away with charging a premium for these kind of upgrades.

Other Applications?

Well, that’s all I’ve come up with for now, but I bet this principle of in-flight upgrades could be applied elsewhere. It seems to me like an untapped revenue source for companies that deliver a service that takes a while to complete.

Server Virtualization and the SMB (part 5)

Conclusion

While server virtualization is not a cure-all, and a properly implemented server virtualization solution may require new hardware, many small and medium size businesses can simplifiy day-to-day operations and increase efficiency by using server virtualization in their infrastructure. In addition, server virtualization makes it easier to manage changes like unexpected server failure and migration to new hardware.
Background Reading
The following articles are good background reading on the subject of server virtualization in the small and medium business.
“Companies with IT teams of one to four people or firms with 60 or fewer employees often don’t have the level of sophistication required to make virtualization pay,” said Chip Nickolett, president of Comprehensive Consulting Solutions that has helped several small businesses take their first steps into the virtual world. “In these environments, the benefit of virtualization would be marginal at best.”
These are not hard-and-fast numbers, of course. Tiny firms in financial services, law and other sectors sometimes have both significant IT requirements, the budget and the staff required to make virtualization pay big dividends.
The use of virtualization technology is expected to grow rapidly in the coming years, especially among the SMBs. Virtualization vendors, who have primarily been targeting the larger businesses thus far, have now started paying more attention to SMBs. Similarly, SMB channel partners are also developing the required skills to offer virtualization-related services. Thus, many SMBs will start using some form of virtualization in the near future and the use of its technology will be fairly common in the next three or four years.
When it comes to disaster recovery with virtualization, you get what you pay for. If your IT budget is too tight to accommodate the most expensive VMware or Citrix packages, don’t expect continuous availability during a disaster.

Using virtualization for disaster recovery makes perfect sense. Virtual machines (VMs) can be packaged with your operating system, applications and configurations and sent off to a secondary location and take over immediately during a disaster at the primary data center site.

Disaster Recovery

The real test of a disaster recovery plan happens after disaster strikes and you need to recover your servers. The more quickly and effectively this can be done, the more quickly you can resume business. Server virtualization offers some unique disaster recovery benefits.
 
You can back up a running virtual machine the same way you back up a single file. All the data and configuration in that virtual machine are backed up. This means that when you need to restore a virtual machine, you are restoring a small group of files rather than hundreds or thousands of files, and after restoration the virtual machine resumes running with the configuration and data it had at the moment you backed it up. Because you do not need to re-configured anything when you restore the server, all of your server applications and data are ready to use immediatly after restoring the virtual machine.
 
Virtual machines are easily portable from one physical server configuration to another. This provides benefits for disaster recovey scenarios because you can restore and run a virtual machine on a different server than the one where you created the backup.

Server Virtualization and the SMB (part 3)

Greater Flexibility

Recent developments in the server virtualization world allow even greater flexibility when you have several servers hosting virtual servers. You can use Live Migration to move a running operating system from one host server to another. With Microsoft’s Hyper-V product, you get this feature essentially for free. If you use VMWare’s product, this feature is an extra-cost add-on. Both products require some specialized hardware for this feature to work, but implementing Live Migration provides a tremendous amount of flexibility, allowing easier maintenance and load balancing for your virtualized servers.
 
For example, if you have two or more virtualization servers configured for Live Migration, you can move running virtual machines from one server to the other so that you can do maintenance on the first server. This reduces downtime for users and makes scheduling maintenance windows easier for IT staff.

Server Virtualization and the SMB (part 2)

Increase Hardware Utilization

Even in smaller business environments, multiple servers are commonly used to run the organizations application workload. Often these  servers are under-utilized. While this spare capacity allows for future growth and spikes in utilization, it also represents wasted money spent on the initial purchase of the server as well as the electrical cost to run a mostly-idle server.
 
By running several server operating systems on a single physical server, you can better utilize the power of that single server while still leaving room for future growth and spikes in utilization. The number of operating systems that you choose to run on a single server depends on business requirements and hardware availability.
