For long-term storage of rarely accessed data in Azure, what is the most cost-efficient storage tier?

Cool
Hot
Archive
Premium

The correct answer is: Archive

The Archive storage tier is specifically designed for the long-term storage of data that is rarely accessed, making it the most cost-efficient option for such a use case. This tier offers significantly lower storage costs compared to the other tiers, which is ideal for data that does not need to be readily available or accessed frequently. Data stored in the Archive tier is typically used for compliance and regulation purposes or for data that must be retained for long periods but is not expected to be retrieved often. While there are retrieval costs and a longer wait time for access compared to other tiers, the savings on storage costs make it advantageous for infrequent access scenarios. This is in contrast to other tiers, which are intended for different access patterns. The Cool tier, for instance, is designed for data that is infrequently accessed but may need to be retrieved more quickly than data in the Archive tier. The Hot tier is used for active data that is accessed frequently and has higher storage costs associated with it. Premium storage is designed for high-performance workloads that require low latency, but it comes with higher costs, which doesn't align with the requirement for cost-efficient long-term storage of rare access data.
