From ComputerWorld: Amazon Web Services launched a new, less-expensive flavor of its cloud-based object storage service meant for data that is infrequently accessed (IA).
Amazon’s Simple Storage Service (S3) IA is an alternative to the company’s standard S3 offering and its Glacier service. Amazon’s three storage offerings now include: S3 for fast access to data; S3 IA, which is less expensive than S3 with a slight tradeoff in availability; and Glacier, which offers even less expensive prices, with high availability but the tradeoff of long latency for retrievals.
AWS says customers can migrate data from one service to another based on how frequently they need to access the data. S3 starts at $0.03/GB/month while IA starts at $0.0125/GB/month with 99% availability, and Glacier starts at $0.007/GB/month. When announcing IA, AWS also dropped the price of Glacier from $0.01 to $0.007 GB/month.
AWS also has a series of Elastic Block Storage (EBS) services meant to provide persistent block-level storage for its Elastic Compute Cloud (EC2) virtual machines.
