Modern Big Data Processing with Hadoop

Cold storage

This storage is very useful for storing important backups in the Cloud that are rarely accessed. Since we are dealing with a special type of data here, we should also be aware that the Cloud vendor might charge significantly high amounts for data access from this storage, as it's meant to be written once and forgetten (until it's needed). The advantage with this mechanism is that we have to pay lesser amounts to store even petabytes of data.
