I'd really love to jump on EC2, but every time I run the numbers it doesn't add up for my usage.<p>I currently colocate all my servers and I wanted to figure out just how much it might cost to potentially switch over to EC2. After much digging and benchmarking, it seems that an single ECU is roughly equivalent to 350 to 400 points on PassMark. With this information and load metrics, it is pretty easy to determine what kind of ECUs I might need to switch over (as RAM and disk are pretty straight forward): <a href="http://www.cpubenchmark.net/cpu_list.php" rel="nofollow">http://www.cpubenchmark.net/cpu_list.php</a>.<p>Came to the same conclusion as I did a few years ago. For my scenario (about a rack of servers, established business, 24/7 usage, capacity to handle for a 10-fold increase in usage (and much more within a 2 hour window))... I save roughly $170,000 over 3 years doing it all (server costs included). This is with 3-year reserved instances.<p>It should be noted that I build our servers from the ground up and do all the ops.
Useful, but no reason to go through a redirector which may change.<p>The direct link to the blog post: <a href="https://blog.cloudvertical.com/2012/10/aws-cost-cheat-sheet-2/" rel="nofollow">https://blog.cloudvertical.com/2012/10/aws-cost-cheat-sheet-...</a><p>The direct link to the PDF with the data: <a href="http://s3.amazonaws.com/CloudVerticalBlog/CloudVertical-AWS-Cost-Cheat-Sheet.pdf" rel="nofollow">http://s3.amazonaws.com/CloudVerticalBlog/CloudVertical-AWS-...</a>
For a 'small timer' like me used to VPS or dedicated local servers it's still a bit confusing.<p>I don't know how much a value it is, but when looking at PAAS options (like openshift, heroku, appengine, etc.), I like appfog's braindead simple pricing: 2gb free, 4gb $100/month, 16gb $380, etc.
Very cool! This is useful for small deployments. We developed PlanForCloud.com to help with cost forecasting for big deployments, where you want to compare infrastructure options and cloud providers.<p>Also, don't forget that one of the key benefit of using the cloud is elasticity, and unless you model this, you won't get accurate estimates. We developed the notion of elasticity patterns[1] to let users do this, so you can say something like "my baseline S3 storage is 100GB, but every month this grows by 5% and in the Christmas it doubles".<p>[1] <a href="http://www.planforcloud.com/pages/docs/patterns.html" rel="nofollow">http://www.planforcloud.com/pages/docs/patterns.html</a>
Great way to make the prices clear. 15% more for Japan, I think it's time to move my things back to US East (Virginia) and make some savings.<p>It had some pricing on S3 but I think it would be nice to also have the prices for RDS. A medium-sized one of those things costs as much as a medium EC2 instance (yes I learned that the hard way).
