Description: Storage tiers in cloud storage are a fundamental feature that allows users to optimize costs by selecting the most suitable storage option based on data access frequency. Different storage service providers offer various storage tiers: Hot, Cool, and Archive. The Hot tier is designed for frequently accessed data, providing fast access and relatively high storage costs. In contrast, the Cool tier is ideal for data that is accessed less frequently, offering lower storage costs but incurring additional access fees. Finally, the Archive tier is intended for data that is rarely used, allowing for very low-cost storage, although with longer retrieval times. This flexibility in selecting storage tiers enables organizations to manage their resources more efficiently, adjusting their expenses based on specific data access needs. Additionally, the ability to move data between these tiers as access needs change contributes to a more dynamic and economical management of cloud storage. In summary, storage tiers in cloud storage are a key tool for optimizing costs and improving efficiency in data management.
