AWS Account Billing

The book I read to research this post was About AWS Account Billing which is a very good book which I downloaded for free from kindle. This book merely tells you about the different types of billing & account and doesn't contain the specific charges. I typed AWS free tier into google and that took me to a web site that contained information on free tier usage. There are 2 types of billing which are consolidated where everything is consolidated into one bill and programmatical where you pay for each service individually. Consolidated makes you ineligible for the free tier service. The free tier service is only available on certain products & only lasts for 12 months. You are allowed upto 15 Gb of usage on free tier but may be charged if you open more than one instance in elastic compute cloud. Also you are generally charged per hour so it might only be a small charge per hour but it adds up over a month. I think if you are tempted to go with Amazon Web Service you need to read about it very carefully & make sure you know roughly what they are going to charge you to avoid any nasty surprises. When you sign up you must give credit card information so they can bill you. Finally I noticed there is a database which is free called Mongo DB and there is other downloadable software some of which is free on the AWS Products & Services website.
