versus-

Windows Azure compute instances come in five unique sizes to enable complex applications and workloads.

Compute Instance Size CPU Memory Instance Storage I/O Performance
Extra Small 1 GHz 768 MB 20 GB* Low
Small 1.6 GHz 1.75 GB 225 GB Moderate
Medium 2 x 1.6 GHz 3.5 GB 490 GB High
Large 4 x 1.6 GHz 7 GB 1,000 GB High
Extra large 8 x 1.6 GHz 14 GB 2,040 GB High

*There is a limitation on the Virtual Hard Drive (VHD) size if you are deploying a Virtual Machine role on an extra small instance. The VHD can only be up to 15 GB.

From Amazon- November seems like a Thanksgiving for prices as well-

————————————————————————————————

lowered the threshold for our volume based discounts from 50 terabytes to 1 terabyte, extending volume pricing discounts to more customers. Here’s a summary of the changes:

Old         New
First 1TB           $0.150    $0.140
Next 49TB         $0.150    $0.125
Next 50TB         $0.140    $0.110
Next 400TB       $0.130    $0.110
Next 500TB       $0.105    $0.095
Next 4000TB     $0.080    $0.080 (no change)
Over 5000TB     $0.055    $0.055 (no change)

These prices apply to Amazon S3 Standard storage in the US-Standard, EU-West, and AP-East regions. The new lower prices for the US-West region and Reduced Redundancy Storage can be found on the Amazon S3 Detail Page.

Amazon EC2 and company announced a free year long tier for new users-you cant beat free 🙂

http://aws.amazon.com/free/

AWS Free Usage Tier

To help new AWS customers get started in the cloud, AWS is introducing a new free usage tier. Beginning November 1, new AWScustomers will be able to run a free Amazon EC2 Micro Instance for a year, while also leveraging a new free usage tier for Amazon S3, Amazon Elastic Block Store, Amazon Elastic Load Balancing, and AWSdata transfer. AWS’s free usage tier can be used for anything you want to run in the cloud: launch new applications, test existing applications in the cloud, or simply gain hands-on experience with AWS.

Below are the highlights of AWS’s new free usage tiers. All are available for one year (except Amazon SimpleDB, SQS, and SNS which are free indefinitely):

Sign Up Now

AWS’s free usage tier startsNovember 1, 2010. A valid creditcard is required to sign up.
See offer terms.

AWS Free Usage Tier (Per Month):

In addition to these services, the AWS Management Console is available at no charge to help you build and manage your application on AWS.

* These free tiers are only available to new AWS customers and are available for 12 months following your AWSsign-up date. When your free usage expires or if your application use exceeds the free usage tiers, you simply pay standard, pay-as-you-go service rates (see each service page for full pricing details). Restrictions apply; see offer terms for more details.

** These free tiers do not expire after 12 months and are available to both existing and new AWS customers indefinitely.

The new AWS free usage tier applies to participating services across all AWS regions: US – N. Virginia, US – N. California, EU – Ireland, and APAC – Singapore. Your free usage is calculated each month across all regions and automatically applied to your bill – free usage does not accumulate.
