Understanding Cloud Tiering and Why It’s the Best Option for Storing Cold Data

Cloud storage gives us the flexibility to store all our important data. It could be used for backups, archives, or even as an extension of local file systems. In the recent years, cloud providers have started offering many different storage tiers. These storage tiers let you optimize the use of storage resources, backup data efficiently, save money, and make the best use of storage technology for each type of data.

Cloud tiering and cloud archiving allow users to move less frequently used data, also known as cold data, from an on-premises file server or Network Attached Storage (NAS) to cheaper and more reliable cloud storage services, usually object storage such as Amazon S3, Azure Blob and Google Cloud Storage. Cloud tiering is a form of data tiering. The term, ‘data tiering’ came from moving data between tiers or classes within a storage system, but it has now also come to mean tiering or archiving data from a storage system to another storage system or cloud. Cloud tiering is increasingly recognized as a necessity to manage enterprise file workloads across a hybrid cloud.

Cloud tiers are generally classified as hot or cold

Data that is frequently accessed is stored in hot tiers and is also called hot data. The storage costs will be higher, but data access will be immediate, and there will be no or low access charges for such data. In addition, there will be no minimum contract lengths for data storage. The data in cold tiers is often referred to as cold data because it is rarely accessed. Storage costs are lower, but there are minimum contract lengths. Data is generally not immediately available, and retrieval can take several hours. Obtaining data will cost significantly more.

Cloud storage has hidden charges

Cloud computing offers inexpensive storage. Nonetheless, there are hidden charges. It is common for cloud providers to charge for both the storage and retrieval of data, as well as egress fees if the data must leave the cloud. Cloud retrieval fees usually appear as API calls to “get” and “put” data into or out of the cloud. Egress fees are based on data read from outside the cloud.

In cloud tiering, cold data is stored economically

Most enterprises have not accessed up to 80% of their actual data in more than a year. With cold data tiering, the on-premises storage array needs to keep only hot data and the latest logs and snapshots. The capacity of the storage array, mirrored/replicated storage array, and backup storage can be dramatically reduced by tiering the cold data, as well as older log files and snapshots. The result is increased recovery speeds and lower recovery costs.

It is possible to reduce backup footprint, backup license costs, and backup storage costs by continuously tiering off unused cold data that isn’t being accessed. Imagine the amount of money you would save by storing around 80% of your data in a cloud tier, which consists of infrequently accessed data such as snapshots, logs, backups, and cold data!

Data Dynamics is a leader in managing unstructured data via its Unified Unstructured Data Management Platform providing data Analytics, Mobility, Security and Compliance. By leveraging the insight, intelligence and automation of the Platform, enterprises drive risk mitigation, enhance data security and optimize their storage, all from a single Platform.

Proven in over 25% of the Fortune 100, the Data Dynamics Platform scales to meet the challenge of global enterprise workloads. Enterprise customers no longer need to deploy individual point solutions nor have siloed views of their data through the power of the Data Dynamics Platform. The Platform accelerates the adoption of hybrid, public and multi-cloud strategies, builds higher quality SLAs, and improves business process modernization.
