João,
Storage is cheap these days. There are many options to share storage between
servers. I've done many records implementations with content-addressable
storage (CAS), which works great for files that don't change (e.g., records).
Multiple servers can access the content over an IP network. Replication
between shelves and over devices ensures backup availability. We've had them
fail over automatically over long distances too. Many fault tolerant
implementations can work in an active-active configuration to help ensure
seamless fail-over and full use of the infrastructure during normal operation.
Performance can be reduced on fail-over, but it least operations continue....
I like the idea of hosting at FamilySearch, and possibly other services.
Perhaps we could get a good index built! They wouldn't want to give up rights
to the content, but perhaps they could find a better way to drive traffic to
their site. Honestly, I just go directly to the content and can't say what
else is on the site....
Regards,
Bill

Victor,
The "cloud" is not free... And while I do agree that on principle it would make
sense, the truth is that the thing that's REALLY expensive on the cloud is
storage. You can get Amazon Web Services to scale easily the number of servers,
but telling that each of those servers would have to be able to store and
replicate several Terabytes of data would probably consume the budget for the
whole archipelago quite fast.
And it doesn't make sense to have several servers all going to the same storage
server wherever they store all those images.
Things that would make sense:1. Allowing Familysearch to serve those images
(pros: free, and no work necessary; cons: nobody would use the CCA servers ever
again).2. See 1., to be honest.

They should load all that data up on the cloud to be fault tolerant. Likely
cheaper and less of a maintenance hassle for the CCA admins.

CCA seems to have gone down this morning around 10:00 am EST. As of now it is
still down. Rick--
