What Is Amazon Glacier?

Amazon Glacier is considered as a cloud storage platform developed and launched by AWS with longer retrieval times. Under this, a developer is meant to use Amazon Glacier for the purpose of moving the less accessible data to archive storage for saving costs on storage.

The database backups can also be moved by the developers for backing up the storage media to the cloud for long-term storage. Earlier, the companies used to pay a lot of money for data archiving. It is an important necessity within the data management operations of a company.

The archiving solutions were available earlier at a high cost, and along with that, the companies had to determine the capacity requirement as well. This was hampering the entire functionality with several drawbacks such as under-utilized capacity and unwanted money expenditures.

Therefore, Amazon Glacier took over this hassle and brought in a convenient and cheaper solution for data backup and archiving. There is more to it that you will get to know while you continue with this article further.

Amazon Glacier Brought a Revolution

Amazon Glacier changed the traditional approach of companies for data archiving. There are no upfront payment conditions with AWS Glacier, and the pricing on usage is very low. AWS is working in the background to handle the heavy operations for executing the data retention needs. Moreover, you get the potential to increase or decrease your usage scale.

AWS management console has direct options for you to easily create or set up an Amazon Glacier storage service. Once you do that, you are accessible to upload numerous amounts of data as per your choice. The Amazon Glacier stores almost all types of data in vaults and archives.

The size of glacier archives ranges between 1 byte to 40 terabytes. In short, there is no limit to uploading data into an archive or creating several archives within AWS Glacier. There is a dedicated multipart upload feature for high reliability and throughput upon the archives that are above the size of 100MB.

AWS users are allowed to group the archives in specific vaults and manage their accessibility through AWS Identity and Access Management (IAM). A host can be assigned to each of the vaults, and notification policies can also be implemented with it. It is solely upon the AWS admin to execute the resource-based access policy for each vault of archives. Hence, the accessibility limits can also be set for the hosts permissible to access selected archives.

Along with the vaults of archives, there is a feature named ‘vault lock’ under which compliance can be set for each of them. Once a lock is initiated, Amazon Glacier implements given configurations for meeting the compliance standards.

Pricing Policy of Amazon Glacier

Amazon Glacier has a very subtle pricing policy under which it charges for every one gigabyte of storage used per month. Uploading the data to Amazon Glacier is free, while the platform charges only for the retrieval requests. It is implemented as such to prevent the customers from solely depending upon Amazon Glacier for their general data storage needs and use it only as storage of archives infused with infrequently used data.
