I am currently having an m1.large instance acting as a memcache server.
I would like to replace that with 2 m1.small nodes for High Availability more or less for the same cost.
But I am concerned about the impact of the moderate IO performance of m1.small.
I read the following as if moderate IO would affect network system as well.
Not sure if the fact that there would be more nodes counterbalance the more limited IO capacity of the small instances.
Anyone had experience with memcache on these instance types that can comment?
Many thanks in advance
