Amazon S3 Glacier is an online file storage web service that provides storage for data archiving and backup. [2]Glacier is part of the Amazon Web Services suite of cloud computing services, and is designed for long-term storage of data that is infrequently accessed and for which retrieval latency times of 3 to 5 hours are acceptable.
Amazon S3 Glacier Flexible Retrieval is also a low-cost option for long-lived data; it offers 3 retrieval speeds, ranging from minutes to hours. Amazon S3 Glacier Deep Archive is the lowest cost storage for long-lived archive data that is accessed less than once per year and is retrieved asynchronously.
This comes a year after the setting up of S3 in Europe. [29] [30] 2009: April: Product (compute) Amazon launches Amazon Elastic MapReduce (EMR), which allows businesses, researchers, data analysts, and developers to easily and cheaply process vast amounts of data. It uses a hosted Hadoop framework running on the web-scale infrastructure of EC2 ...

Amazon does not charge for the bandwidth for communications between EC2 instances and S3 storage "in the same region." Accessing S3 data stored in a different region (for example, data stored in Europe from a US East Coast EC2 instance) will be billed at Amazon's normal rates. S3-based storage is priced per gigabyte per month.
Through images Icefin beamed back, they discovered the glacier is melting in unexpected ways, with warm ocean water able to funnel through deep cracks and “staircase” formations in the ice.
The Laurentide ice sheet (LIS) was a massive sheet of ice that covered millions of square miles, including most of Canada and a large portion of the Northern United States, multiple times during the Quaternary glaciation epochs, from 2.58 million years ago to the present.
They can be up to 10 meters wide and are typically found on ice sheets and flat areas of a glacier in a region of transverse crevasses. Moulins can reach the bottom of the glacier, hundreds of meters deep, [3] [4] [5] or may only reach the depth of common crevasse formation (about 10–40 m) where the stream flows englacially. [6]
