Cold Storage Archive Services

Due to the budgetary challenges of storing vast amounts of data in the cloud, cold storage is emerging as a significant trend. Some CSPs have introduced cold storage services that offer lower data storage costs and correspondingly lower performance levels. In other cases, cloud services are implementing cold storage behind the scenes; for example, they may automatically move older and less frequently accessed data to a lower-performance tier.

Four interrelated requirements are relevant to most cold storage usage models. It's increasingly common to quantify and explicitly specify one or more of these requirements in cold storage service-level agreements (SLAs) between the customer and the CSP.

  • Expected storage life: Cold storage is designed for persistent rather than transient data. This is reflected in the cold storage SLA, which is triggered by the fact that the data is considered important enough to retain and therefore requires long-term storage.
  • Access frequency: As data ages, it tends to be less frequently accessed and therefore becomes more suited to cold storage. This may be explicitly specified in the SLA: data is moved to cold storage based on the date and time it was last accessed.
  • Access speed: Cold storage explicitly assumes that lower performance is acceptable for older data. The SLA defines which data is needed immediately and which can wait.
  • Cost: The benefit of cold storage is the reduced cost of storing older and less frequently accessed data. For some usage models, this overrides any other considerations. Meeting the SLA requires use of the lowest cost infrastructure. Everything else is secondary.
