R Programming By Example

Flexibility and power with cloud computing

Sometimes, you don't even need more computing power or efficient resources usage. Sometimes, you just need to run R on some other computer without tying up your own for hours or days. In those cases, using cloud computing resources can be very useful.

Cloud computing resources are not only useful when you want to use an extra machine, they are a very efficient way to get hold of supercomputers to do some work for you. It's very easy to build a machine with 64 CPU cores and 512 GB of RAM memory. Using a system like that may be cheaper than you think, and it can be leveraged for very costly computations that would take way too much time in commodity hardware.
