Warm Storage
Warm storage is a data storage tier that balances accessibility and cost, designed for data that is accessed less frequently than hot storage but more often than cold storage. It typically offers lower latency and higher retrieval costs than cold storage, but higher costs and faster access than archival solutions. This tier is commonly used in cloud storage architectures to optimize performance and expenses for semi-active data.
Developers should use warm storage when dealing with data that requires occasional access, such as historical logs, backups, or compliance records, where immediate retrieval is not critical but still necessary within minutes to hours. It is ideal for reducing costs compared to hot storage while avoiding the high latency and retrieval fees of cold storage, making it suitable for analytics, regulatory audits, or infrequent user data access.
