We’re excited to announce some price changes for Amazon S3 and Amazon EC2, as well as a special data transfer promotion that will run until June 30, 2010.

Amazon S3 Storage Pricing Tiers

As Amazon S3 has grown, so has the number of customers storing large amounts of data in the service. To assist these customers, we are reducing the price of our 500 TB tier. We are also introducing new pricing tiers in all Amazon S3 Regions at the 1 PB and 5 PB levels. These changes reduce storage costs for multi-petabyte customers by more than 15%, and reduce the price of our highest tier by more than 50% in the US Standard and EU (Ireland) Regions.

Amazon S3 EU (Ireland) Pricing

We are reducing the price of Amazon S3 in the EU (Ireland) Region by over 15% across all of our storage tiers. We have lowered our base price tier to $0.150 per GB. We are also reducing Request prices from $0.012 to $0.010 per 10,000 GET requests or 1,000 PUT requests.

Amazon EC2 Windows Instance EU (Ireland) Pricing

We are reducing the price of Amazon EC2 Windows and SQL Server instances in the EU (Ireland) Region by more than 5% to $0.12 per small Windows instance hour.

Free Inbound Data Transfer (until June 30, 2010)

Data Transfer into AWS will be free of charge from now through June 30th, 2010, making it even easier for customers to get their data into AWS. Other applicable charges for use of these services continue to apply.
