AWS, Azure and GCP offer data storage services that include a range of options in term of cost and performance. You can choose from several different storage classes (and pricing) depending on how frequently the data will be accessed, how long you need to store the data, and the redundancy and availability required. In the ideal settings, you should have the storage classes that are best for your business, and for the best price. **Storage Classes** Below are generic storage classes: - AWS S3, Azure Blob Storage (no minimum storage duration): Best for data that is frequently accessed and/or stored for only brief periods of time. - AWS S3-SIA, GCP nearline (30-day storage duration/cool storage): Low-cost, highly durable storage service for storing infrequently accessed data. Customers generally use this class for storage, backups, and for disaster recovery files. - GCP Coldline (30-to-90-day storage duration): Very-low-cost, highly durable storage service for storing infrequently accessed data. Ideal for data you plan to read or modify once a quarter (e.g. secondary backup data). - GCP Archival/ AWS glacier/Azure Archive (90-to-180-day storage duration/cold storage): It is the lowest-cost, highly durable storage service for data archiving, online backup, and disaster recovery. This class offers different data retrieval options (5-10mn for active retrieval up to 12 hrs for bulk retrieval) to fit your use case. **Storage Class Optimization** Paying attention to storage utilization and configuration can result in substantial cost savings. You should categorize your storage needs from warmer to colder classes according to actual and projected consumption. It’s possible that the storage class that you have chosen when you first set up your environment may no longer be appropriate. Storage consumption analysis could be complex and time-consuming: you should leverage native tools to manage your storage lifecycle. AWS S3 Lifecycle Policy ensures automatic data transfer to different storage classes by defining duration threshold to move data to cooler storage option. GCP and Azure offer similar services with GCP Object Lifecycle management or Azure Storage Explorer. **Data Deduplication** Files or volumes that are backed up weekly create a large amount of duplicate data hence impact your storage costs. This is where the deduplication process make sense: by eliminating multiple blocks of the same data, you reduce your data footprint, and concurrently, your storage requirements and costs. This process requires set up of specific commands within native services. Azure offers a data deduplication set up through server manager, AWS has a managed service FSx for window files and GCP has commands to deduplicate data in BigQuery. The Optimization and Deduplication steps should be implemented on a regular frequency as your cloud consumption and your storage needs evolve over time.
