When I bring up an EC2 instance, I noticed that virtual memory is not enabled.
$ free total used free shared buffers cached Mem: 1017260 344956 672304 60 141252 136976 -/+ buffers/cache: 66728 950532 Swap: 0 0 0
Where as in a typical Linux installation, it would create swap partition by default. Is there any reason that virtual memory is not enabled on EC2 by default? Or is the memory my EC2 getting already part-physical / part-swap?
