Why Object Storage?

We have been seeing increasing demand for our object storage product, Bulk Storage over the past few months, which is exciting for us because we think that object storage is a phenomenal storage solution for many specific applications. We wanted to provide our followers with an overview of object storage technology and highlight some effective use cases. The biggest hurdle we see to adoption of our Bulk Storage product is an understanding of how exactly the technology can be used. As a result of this, a big portion of our job at Cloud-A is to play matchmaker and point users in the direction of existing third party software solutions that integrate with object storage.

What is Object Storage?

Object Storage is an extremely simple yet scalable and reliable file storage system that has been made popular by Amazon’s S3 product, the world’s most recognized object storage deployment. In addition to S3, OpenStack Swift is an open source project that allows organizations to build out their own object storage solutions – Swift is what Cloud-A Bulk Storage is built with. For organizations who prefer to keep their data within their own walls, and do not have in-house development talent or experience to build their own Swift deployment, SwiftStack provides a vendor supported, optimized and hardened solution for on-prem object storage solutions.

Rather than organizing files in a directory, object storage stores files in a flat organization called containers, and unique identifiers or “keys” are used to retrieve them. Object storage requires less metadata than traditional file systems do to store and access files by grouping metadata with each object. Object storage offers basic functionality, allowing users to store, retrieve, copy, and delete files and most object storage systems provide a REST API that allows users to programmatically integrate with containers and objects.



The simplicity of object storage makes it incredibly scalable. Scaling an object storage cluster is as simple as adding additional nodes.


Object storage achieves reliability by replicating objects across multiple hard disks, nodes, and geographical locations.

Cost Effective

Since object storage is “software defined,” clusters can be built on commodity hardware, avoiding the cost of specialised appliances. This paired with the economies of scale that a cloud provider like Cloud-A achieves enables the price point of object storage to be much lower than traditional network attached storage (NAS) solutions.

Object Storage Limitations

Object storage is built for unstructured data within cloud applications. The technology was not built to replace block storage for operating systems and databases, which are both structured data. Object storage in a public cloud setting generally has a lower throughput than traditional storage systems.

Use Cases

Content Repository

Object storage makes for an excellent solution to house content repositories for web & mobile applications. A single, web-addressable namespace is used rather than putting infrastructure knowledge in the application.

These applications access data via native HTTP RESTful APIs and developers leverage broad API support for programming languages including Java, C, C#, Python, PHP, Ruby, and others.

Recently at Cloud-A we have seen more and more users serving static files from Bulk Storage as an alternative storage backend for content management systems like Drupal or WordPress.

Large-File Workflows

Several industries that store and archive large files like video production, life sciences and research have found object storage to be an extremely useful storage solution. The scalability of object storage, both in public or private deployments, allows organizations to distribute their data across multiple regions for essentially unlimited amounts of capacity.

Most of these large-file use cases involve industry specific software that has been modernized to support cloud storage APIs like the OpenStack Swift API.

Document Sync & Sharing

One of the largest consumers of Cloud-A Bulk Storage is third party sync and share solutions. Organizations are champing at the bit for DropBox-like solutions that are under their own control.

Object Storage provides an excellent storage backend for sync and share as it allows organizations to store unlimited documents and unstructured data, all accessed with no compatibility issues or data lock-in. Cloud-A Bulk Storage, powered by OpenStack Swift supports a wide range of third-party file sync services and document management systems such as:

CTERA Enterprise File Sync & Share

CTERA provides an enterprise-grade alternative to consumer cloud services, utilizing cloud infrastructure that is completely under ITs control, and providing end-to-end security.

Big Data Repository

Object storage can provide a repository for incoming data, as well as the results of analysis and modeling in big data use cases.

Object storage provides simple storage management, allows organizations to avoid silos and sharding, and fast access to any data either as files or as native objects from Hadoop and other analytic tools.

Utilizing the Hadoop Swift Filesystem client, organizations can leverage OpenStack Swift deployments like Cloud-A Bulk Storage for their Hadoop workflows. The Hadoop Swift filesystem library defines which Swift object hosts a container – and how to connect to it.


Architected, developed, and built completely in the open, Hortonworks Data Platform (HDP) provides an enterprise ready data platform that enables organizations to adopt a Modern Data Architecture.

Backup and DR and Archival Storage

Another leading use case for Cloud-A Bulk Storage is backup, disaster recovery and archival storage. Object storage provides a resilient and easily scaled storage target for backups of VMs, files, and databases.

As a backup target, object storage can provide a much lower-cost solution than other on-premise storage options. Native data replication in object storage technology like OpenStack Swift ensures that backups remain available even if a server, site or network fails.
