When you start a new project on Amazon AWS, expecially for little projects, you must take care about istance cost. Yes, AWS is cost effective for small projects but evaluating how much cost your EC2 infrastructure is very hard.
Evaluating costs
You have some standard possible choice to do this task about evaluate how much your EC2 instances costs:
The problem
The main problem is that the pricing is continuous changing over time; it's very difficult to compare all the stuffs related like: Cores, ECU, Memory amount and monthly costs. From original service introduction in 2006 there's many announcement over time. Yes, billing page resume in your account can help you, but we can do better.
The solution
Would you like to compare more quick and easily the pricing? Yes, and we can use EC2Instances.info
This site was created out of frustration while trying to compare EC2 instances using Amazon's instance type and pricing pages
The updates is very frequently, based on Amazon blog page announces; if you want more frequently updates you can download the source code in order to run on your workstation and scraping the EC2 pricing pages.I think that site is a great idea: simple, fast; for who like me that hate Amazon's comparison tables. Maybe the major flaw that's the table doesn't permit to select different Regions and any mechanism to export your choices. Also in the future i hope that the guy will introduce volume pricing.
Update on 21/06/2017
Great news! The site has implemented Reserved Instances comparison; now you can compare cost and payment terms for all Reserved Instances options (all upfront, partial upfront etc..)I hoping this helps you to better compare and choose new instances based on your demand and that Amazon can learn from this type of comparisons costs.
