Scale Changes Everything
So, you are sold, you are ready to build your own robotics IT factory, what’s next?
Shall we build a compute cloud?
NO
We will build web applications that brokers access to compute resources.
NO

Joe Armstrong
if p( fail | one unit) = 10-3 then
p( fail | n units) = 10-3xn
Isolation
if p( fail | one unit) = 10-3 then
p( fail | n units) = 10-3xn
Isolation
So 10 nines should be easy, we just need 4 units, amirite?
n > 1

Some people, when confronted with a problem, think “I know, I'll use a message bus.”

But wait, the cloud IS an application?
How do we build and deploy that?

If a cloud falls in a forest and no one is there to hear it, do we still have 100% uptime?
