The cloud service giant announced on its blog that it has cut the price of indexed storage by 75 percent in all regions, while the price of provisioned throughput capacity has fallen by 35 per cent.
Amazon's indexed storage is free for the first 100MB to European customers and then $0.283 (£0.0188) per GB per month thereafter. Meanwhile, provisioned throughput capacity for the same region is $0.00735 (£0.00488) per hour for every 10 units of write capacity and $0.00735 (£0.00488) per hour for every 50 units of read capacity.
Amazon is also offering a reserved capacity pricing model to customers that are able to predict how much capacity they will need in the future.
"If you need at least 5,000 read or write capacity units over a one or three year time period you can now enjoy savings that range from 54 percent to 77 percent when computed using the newly reduced on-demand pricing," said Jeff Barr, AWS chief evangelist, in his blog post.
Since DynamoDB was launched, Amazon has introduced several other big data and enterprise-focused services such as Data Pipeline but it still faces strong competition from those the likes of Rackspace, who recently entered into the NoSQL database service with its acquisition of ObjectRocket and its MongoDB technology.
