Step-by-step explanation:
Amazon Glacier is an AWS service designed for long-term data archival. It is a low-cost storage option that is optimized for data that is rarely accessed but still needs to be retained for compliance or business purposes. With Glacier, you can store large amounts of data with high durability and retrieval options that can take hours or days.
For example, Glacier would be a good choice for storing backup data, archives, or historical records that you may need to access infrequently.
Unlike Amazon S3, which provides immediate access to your data, Glacier is optimized for archival purposes, offering lower storage costs but longer retrieval times. When you want to retrieve your data from Glacier, you need to initiate a retrieval job, which can take several hours or even days to complete.
