Explanation

Azure Blob is the only Azure storage option that supports access tiers. The default is the Hot tier, which is designed for frequently accessed data. The Cool tier is optimized for data that will be stored for at least 30 days. The Cool tier has lower storage cost than the Hot tier but higher costs for early access. The Archive tier is designed for data that is rarely accessed and will remain in storage for at least 180 days. Access to Archive tier data requires the data to be rehydrated to a Hot or Cool tier. This can mean a latency of several hours. Access tier support requires Data Lake Storage Gen2. Azure Blob also supports two performance tiers. The Standard performance tier provides for high performance using hard disk-based storage media. The Premium performance provides greater throughput than the Standard tier and uses solid state drive (SSD) media. The Standard and Premium tiers are also supported for other storage options including Azure File storage and Azure SQL Database. Azure Table and Azure File do not support access tiers. Access tiers is a feature supported through Cosmos DB. Azure Table and Azure File are distinct storage types and are not implemented through Cosmos DB APIs. Table storage is used for storing structured, non- relational data. File storage provides file storage with shared access, similar to a file server.
