I ran a m2.2xlarge for some periodic processing. My last major invoice was from January
$1.020 per High Memory Two Extra Large (m2.2xlarge) Windows instance-hour (or partial hour) * 335 = $341 It had 34 gb of ram and 4 cores. It was enough for what I was doing. Being on windows was nice too so I could just RDP (remote desktop) in and not mess around with XWindows Do you need the extra RAM and extra cores? I was mostly using 2 cores since R / J are single threaded. I did have a routine where I spun up 8 instances to process chunks of 57 billion rows of data. I may have switched the instance type for the job. It's fairly easy to re-provision your image on a different instance type when things get real heavy and run a more moderate instance type for regular processing. Here's the actual charges. I agree that Amazon sometimes feels a bit difficult to determine what you'll actually pay: http://pasteboard.co/2q7Mxjvx.png On Wed, Aug 20, 2014 at 2:55 AM, Raul Miller <[email protected]> wrote: > Ick.
