Reliability in a data system means fault tolerance above all: the system keeps working when a network link is cut or a node dies. (opens korrents.com)
“for me, reliability means fault tolerance primarily. So, meaning that a system should, on the whole, continue working even if like a network link is interrupted or a node crashes or something like that.”
-
Scalability is not a property a system has; it is the set of mechanisms it has for coping with a change in load. (opens korrents.com)
“Scalability is just like what mechanisms we have for dealing with changes in load. If load increases, how can we add computing capacity to a system, for example, so that the system still continues working?”
-
Scaling down is half of scalability: cost and capacity should track load in both directions, right down to a service that is nearly free to run. (opens korrents.com)
“generally, like you just want the the cost and the computing capacity to be roughly proportional to the load that you have. And at the low end, that means actually being able to scale down to something that is…”
