 Cloud storage has changed the rules for deploying simpler, infinitely scalable and more affordable storage. So it makes little sense to burden a cloud storage platform with storage systems that are based on 20th century file systems that inhibit administration, scalability and cost.
Selecting the correct underlying storage system can greatly impact the success or failure of implementing cloud storage. The characteristics of object storage are ideally aligned with a cloud storage infrastructure, delivering a superior cloud storage experience with better scalability, accessibility and affordability, according to Caringo Inc.. Here are five reasons an object storage infrastructure should be the foundation for a cloud storage system according to that company:
1. Object storage magnifies the cost efficiency of cloud storage
A key to the cost efficiency delivered with cloud storage is to begin with an affordable storage system. The complexities and restrictions of outmoded file systems that power traditional NAS and SAN storage arrays can easily offset the potential cost savings of cloud storage by complicating storage administration, limiting scalability with artificial capacity caps and enforcing vendor lock-in with expensive, proprietary hardware.
Object storage is a much better fit for cloud infrastructures. Instead of using a complex, difficult to manage and antiquated file system, object storage systems leverage a single flat address space that enables the automatic routing of data to the right storage systems, specifies the content lifecycle and keeps both active and archive data in a single tier with the appropriate protection levels. This allows object storage to provide better value by aligning the value of data and the cost of storing it without requiring oppressive management overhead to manually move data to the proper tier while providing infinite scalability to support the capacity-on-demand capability of cloud storage. Object storage is also designed to run at peak efficiency on commodity server hardware.
2. Object storage provides easy access to storage anywhere, any time to any device via HTTP
Cloud storage is commonly delivered as a storage as a service application via the Internet, so using HTTP as the primary protocol to access object storage pools vastly simplifies the process for cloud storage providers to integrate object storage systems into their service offerings.
3. Object storage provides unlimited capacity to support cloud storage elasticity for storage on demand
In object storage systems there is no directory hierarchy (or “tree”) and the object’s location does not have to be specified the way a file’s directory path has to be known to retrieve it. This location transparency enables object storage systems to scale to petabytes and beyond without limits on the number of files (objects), file size, or file system capacity, such as the 2 terabyte restriction that is common for Windows and Linux file systems.
4. Object storage performance scales as the cluster grows, eliminating hot spots
In an object storage cluster, performance scales linearly as more nodes are added. As new server nodes running on commodity hardware come online, they provide massively parallel increases in both processing and I/O capacity across the cluster. Additionally, the object storage cluster is totally symmetrical, allowing the workload to be automatically load balanced across all nodes in the cluster and avoiding hot-spots to better support cloud bursting and other peak demand events.
5. Object storage eliminates the need for cloud backup & recovery
In a cloud storage system the old paradigm of data protection via backup and recovery is eliminated as the entire object storage cluster is an online, scalable file repository, not a backup or offline archive solution. All files are always online and available, doing away with the cost and administrative overhead of a separate backup application with no more worries about meeting backup windows or recovery time objectives.
