Knowing all the different features of Windows Azure and what the corresponding fees are, can help you estimate your expenses for running an application in the cloud. It can also help you develop new applications in a way that they consume lower numbers of billable resources — drastically reducing your monthly bill.
Each instance of your Azure application runs on a separate virtual machine. You have to choose the type of these virtual machines depending on the needs of your application. Microsoft has provided the following details for comparison:
|Size||CPU cores||Memory||Disk Space
Web / Worker
|ExtraSmall||Shared||768 MB||~ 20 GB||20 GB||5||$0.04|
|Small||1||1.75 GB||~ 230 GB||165 GB||100||$0.12|
|Medium||2||3.5 GB||~ 500 GB||340 GB||200||$0.24|
|Large||4||7 GB||~ 1 TB||850 GB||400||$0.48|
|ExtraLarge||8||14 GB||~ 2 TB||1890 GB||800||$0.96|
Some Basic Facts About Pricing
With Windows Azure, every started hour is a billed hour. Keep in mind that all these resources get reserved for your application once you deploy your application and you’re paying for them — whether your application is using them completely or not. Even if your applications are not running at all, you will still be charged for the allocated resources. That’s why you need to be careful when designing your application and when you set the configuration settings for it in Windows Azure. You are responsible for removing the instances of unused applications and for allocating more or less resources for your running applications when they need them.
Other features you will be charged for are as follows:
You can find more information on actual prices on the Windows Azure official website.
There you can also find an Azure pricing calculator, which can help you in estimating your costs.
It is an easy-to-use application. You simply specify the amount of resources your application will be using and the calculator gives you the price for running it in Windows Azure.
You now know all the important information about Windows Azure design, its pros and cons, and its pricing. If you haven’t yet decided whether to use it for running your applications or not, then our next article on Windows Azure Security may help you to make your choice.
