Two Birds, One Stone

OK. New idea. Some statements first, I believe them to be true but not positive obviously.

 

1) The vast majority of the servers are grossly under-populated

2) They chose to patch at the lowest perceived server-load time, to inconvenience the fewest people.

3) They don't have a mirrored server environment. Aka two exact copies of every server (like many critical webapp enterprise companies do)

4) Assuming these servers are running on virtual boxes

 

Merge many of the servers. Half as many might be over the top, but for the purposes of easy math lets say that.

Then you have enough overhead to have duplicates of each server, with no increase in overhead costs.

 

This would allow them to apply patches to the unused half, take the live servers down for just a few minutes and bring up the other set, newly patched. Then patch to their hearts content on the other machines (now down), rinse and repeat the next time they have a patch.

 

The servers get better population levels, and patching takes moments on the customer's end instead of 4 hours.
