Hi all, Does anyone know if a template exists for what it takes to

availability, 4 9's etc.for Internet data centers? Specifically I'm looking for something that would say "if you want 5 9's of availability, here's what you need to do", and so on.

For 5 9s you need:

1) Lots of money 2) Lots of clue 3) Lots of luck 4) Lots of balls

You can do 4 9s with any 3 of the above.

Too true.

But you forgot to include 'halfway-clued management' - without that you haven't got a hope in hell of even getting three 9's. ;)

Covered under 2 (above). You need clued mgmnt even to ask for it, let alone "pay" for it. Non-clued management gets ingress filtered at the initial cost estimate layer, for cost-estimate layers that are properly operational.
