Amazon Web Services (AWS) is offering a free one-year 'instance' of its EC2 hosted computing system.
The company said that developers and businesses can use the tier to run one Amazon EC2 instance, including storage, load balancing and data transfer.
Amazon is looking to attract companies that have not been tempted by hosted computing resources, but may be looking to increase their development and use of applications.
However, firms should be aware that popular applications could end up incurring a charge. Amazon said that any applications that spike in popularity would be switched over to the AWS pay-as-you-go, standard pricing model.
Signing up to its service should give developers a good impression of how their applications perform under considerable use, according to Adam Selipsky, vice president of AWS.
"We are excited to introduce a free use tier for new customers to help them get started on AWS. Everyone from entrepreneurial college students to developers at Fortune 500 companies can now launch new applications at zero expense and with the peace of mind that they can instantly scale to accommodate growth," he said.
"We can't wait to see what great ideas are set in motion now that it's free to experiment and launch production applications in the AWS cloud."
The free service launches on 1 November, and new AWS users will get an EC2 instance, as well as access to and resources from Amazon Elastic Block Store, Amazon Elastic Load Balancing and AWS data transfer.
The free 12-month package breaks down into 750 hours per month of micro Linux Amazon EC2 instance use, 750 hours per month of Amazon Elastic Load Balancer, 10GB per month of Amazon Elastic Block Storage, 5GB per month of Amazon S3 Storage, 30GB per month of internet data transfer (15GB 'in' and 15GB 'out' across all services), 25 machine hours per month of Amazon SimpleDB, and 100,000 requests per month of Amazon Simple Queue Service.
Other features, including 100,000 requests per month, 100,000 notifications over HTTP per month, and 1,000 notifications over email per month for Amazon Simple Notification Service, will be available for free indefinitely.
Amazon also announced its financial results this week, reporting profit gains across the board. Revenues grew to £4.8bn, a 39 per cent gain against the same quarter last year.
The company launched a cheaper Kindle e-book reader in August, which was a bestselling product on Amazon.com and Amazon.co.uk.
Amazon is expecting to make more gains in the fourth quarter, which includes the important Christmas holidays, and is predicting increases in sales of as much as 40 per cent.
