AWS Technical Essentials Practice

Amazon Glacier is primarily designed for long-term archiving of data. It provides a low-cost storage solution for data that is infrequently accessed but needs to be retained for long periods. Organizations often require storage for historical records, compliance data, or backups that don't need to be accessed frequently. Amazon Glacier optimizes costs for this kind of storage, making it ideal for such scenarios.

It is worth noting that options related to real-time data processing, temporary file storage, and fast access to frequently used data do not align with Glacier's functionality. While these may be important aspects of data storage and processing within the AWS ecosystem, they are specifically addressed by other services such as Amazon S3 for standard storage needs or solutions like Amazon EBS for quick access to data. Glacier's unique attribute lies in its ability to offer a secure, durable storage solution with minimal cost, tailored specifically for data that can tolerate retrieval times of several hours, making it the preferred choice for long-term data archiving.
