<div dir="ltr"><div class="gmail_quote"><br><div>I am considering using EC2 for a web application.</div><div>I am not sure how to calculate the payment per month.</div><div>Do I pay only for the time someone makes a request?</div>
<div>For example, I have a user who requests a certain report and it takes 1 second to load the report request form, then 20 seconds to produce the report and print it.</div><div>I understand that I pay for 21 seconds?</div>
<div>So if I have 100 customers doing the same thing each day, I pay for 35 minutes (2100 seconds)?</div><div><br></div><div>It seems to be very cheap.</div><div><br><br></div></div></div></blockquote><div><br>Pretty simple. Each instance has a price per hour (or part of it). Multiply the price per hour, per number of hours your instance runs (for a server, that would be 24/7, which means 672 [Feb] /720 [30d months] / 744 [31d months] hours a month), and you have your price. Add to that your network traffic and EBS storage if used, and that's how much you're going to pay.<br>
<br>I wouldn't call that cheap...<br><br>In general I believe that using the Cloud is good only for people who upscale/downscale their platform all the time (for example, use X4 the power only 1/4 of the day) - or for people who set up and teardown demo's all the time and cannot talk a virtualization platform with them.... On probably any other scenario, a VPS/your own server in colocation is considerably cheaper IMHO. But perhaps that's just me.<br>
