If you want to benefit from cold storage, make sure that you use it just in case of an emergency. Learn the best practices around cold storage in the following whitepaper: Requests are more expensive for cold storage within one cloud system.There may be a delay between the request and the actual data access.Nevertheless, there are some additional nuances compared to cool data storage: This is the best solution for large old backup archives. Cold DataĬold storage is a facility for inactive data, which is unlikely to be accessed more than once a year. If you access data too often, the request cost will be inadmissibly high, and cool storage price advantages disappear. **Free if there is no early deletion chargeĪs you can see, the major cool data concern is planning. In the comparison below we took the price* for the monthly transfer volume equal to 5TB and the cloud region is the US: Note: object overwriting is considered as early deletion too. If you store 1,000GB on day 1 and then remove it on day 15, the fee will be: Let’s take Google Nearline with 30 days storing period as an example. If you remove files before the minimum storing period is up, you will have to pay for every remaining day. Early deletion fee is another expenditure item.It’s an additional service fee charged besides data transfer. There is a data retrieval charge for every GB of downloaded data.The storage cost is lower for cold data, but it has extra data operation fees: These are disaster recovery data, backups, outdated sync data and files with a long retention cycle. Cool DataĬool storage is intended for data that is rarely required but may suddenly become crucial. But the best way to accelerate the transfer speed is to choose a data center close to prospective users, even if the cost will increase. On the Microsoft Azure data transfer pricing page, you can see that it’s twice more expensive to retrieve from Brazil. It works exactly like the storage volume discount, which we mentioned in our comparison of cloud storage for backup.Īnother concern is the distance, as some cloud providers increase the fee if you download data from particular regions. For instance, if your download exceeds 10TB, Amazon charges next 30TB within the current month for $0.085 per GB which is $0.005 less. The more data you transfer, the cheaper one GB is. Metadata retrieval, communication, authentication, etc. Requests (per 10,000)ĭata upload and object management within a cloud So, if you upload 100 files and download 300 files daily, 10,000 packages will last for 25 days. Each download/upload iteration requires one request per object. We chose 10,000 requests as an example for requests pricing comparison. **Download to China costs $0.22 and to Australia – $0.18. *Depends on if the region is out of the multi-regional location, e.g. In the comparison below, the monthly transfer volume is 5TB and the cloud region is the US: Data Transfer (per GB) Now let’s consider offerings and prices*. In practice, backup data is moved to a cooler tier after a few months upon creation. For backup, hot data means working documents and recent backups. That means that a user can frequently upload, download and restructure files. Comparison of Requests and Data Transfer Prices in Azure, Google and AWS Hot DataĪll standard cloud storage facilities are designed as hot tier storage. In reality, each data transfer needs at least one request for each object in the cloud, so it’s an integral storage bill part. For example, PUT requests are resource-demanding, so they are more expensive and are usually distributed by 1,000 packs. The pack size depends on the request cost. As a rule, all requests are paid except commands for data deletion.Ĭloud providers usually charge for 1,000 and 10,000 request packs. Requests are data operations within the storage, e.g.Transfer within one cloud region and upload is usually free. Data transfer is charged for every GB downloaded from the cloud or moved to another cloud facility.The storage tier defines the price for data transfer, so let’s check all of them.Įach user’s data access activity consists of two parts with respective fees: Based on the required access frequency, all data is subdivided into 3 categories (tiers): hot, cool and cold, which is explained in our article with top cloud storage providers pricing comparison.
