Standard storage type: Provide general-purpose Object storage services, suitable for frequently-accessed and hotspot-prone data, such as audios, videos, pictures and Website static resources, as well as the data with lower latency and high throughput performance.
Infrequent access storage type: Suitable for infrequent access business scenarios, and suitable for long-term storage and less-frequently-accessed data. Infrequent access storage can keep the access latency at a millisecond level while reducing the storage prices. It can ensure no-wait and high-speed reading for users’ data retrieval scenarios. However, it has certain requirements on storage duration. If a document with less than 30 days’ storage duration is deleted in advance, certain costs will be incurred. Whether for intranet or extranet, data retrieval will also incur costs.
