What is object storage?

Object storage is a computer data storage architecture that stores and manages large volumes of unstructured data using distinct data units or objects. Each object has a metadata and a unique identifier that users can use to retrieve and access data. Users can also customize the metadata to add contextual information for easy retrieval later. Object storage systems don’t organize files using a hierarchical path, making storing data in a flat environment easy. Object storage solutions store data in a global storage pool, meaning users can query and find the exact data they need using RESTful APIs, HTTP, and HTTPS. The flat environment enables users to easily locate the data they need, no matter where it's stored—be it across various devices or in different geographical locations.

What are the common features of object storage providers?

The following are some core features within object storage solutions that can help users in several ways: Scale-out architecture: Object storage software is supported by a distributed scale-out architecture. Within the architecture, several clusters of nodes exist, and these nodes contribute to the total amount of space available for storage. Users can also add nodes independently by parallelly adding them to increase capacity. Adding these nodal points provides massive scaling, even up to petabytes of data. Metadata: The metadata feature is used in combination with several policy-based management capabilities to manage several data services, such as data protection, placement, compression, retention, deduplication, and deletion. Multi-tenant nature: Object storage solutions separate infrastructure and users' needs using multi-tenancy. Data cannot be accessed by other tenants sharing the same infrastructure. This is especially useful for businesses that want to provide each department with storage space, with accessibility given to the specific department only. Global namespace: A namespace is a set of signs that identify and refer to different objects. It ensures that objects are given unique names so that they can be identified easily. A namespace is a global feature, meaning that although data is stored in different locations, it will provide a common view to the user. This feature of object storage ensures nondisruptive performance, load balancing, and increased performance efficiency. Automation: If a service crashes or a site suddenly becomes unavailable due to faults, the object storage system automatically activates the redundant components and services (duplicates) to prevent operations from being affected. Object storage solutions are, therefore, considered self-healing or auto-healing in nature. This important feature helps companies drastically minimize downtime.

What are the benefits of object storage solutions?

Scalability: Discrete units of data are stored within an object, such as servers or storage boxes, within the data center's infrastructure. In case additional processing is required, the data center infrastructure provider needs to add server boxes parallel to the storage cluster. Storing large amounts of unstructured data: Big data growth is explosive with the advent of internet communications and is still growing every second. The large amounts of unstructured data being generated require a strong storage architecture to ensure scalability, and object storage software is one of the best options for supporting unstructured data or big data. Increased efficiency: Accessing data in a file system is a complex task since there are numerous folders and hierarchies to navigate. In the object storage system, information is immediately retrieved via metadata. This results in increased performance since the time to retrieve data is shortened significantly. Disaster recovery support: Object-based storage solutions allow the user to configure the system to duplicate content. Due to any unforeseen activity or a disaster, the disk within a particular cluster may fail. However, since the data has been replicated, the system will continue to operate without any interruptions. The data can be replicated within nodes and several data centers located at different geographical locations. Cost-effective: One of the main cost savings comes in the form of no upfront cost since an object storage software provider would manage the hardware or servers. A user does not need to purchase several servers and storage systems and set up an IT infrastructure, thereby saving initial costs. In addition, object storage providers offer the service as a pay-as-you-go subscription fee; therefore, no upfront investment is required. Compatibility with cloud computing: Object storage is known for its compatibility with cloud computing. Object storage primarily uses cloud services or hosting services to provide storage services. Since the data is stored in the cloud (public cloud or private cloud), the company faces no major upfront cost. In addition, a company can share storage repositories among different departments within the organization, each with a dedicated resource or space. Simplified manageability: As the amount of data continues to grow, a new approach is required to manage the data, and this is where object storage comes into play. Since object software manages a “name” and not the rack of storage, the difference is huge. The namespace could be located in different locations or local sites, in a single storage box, or within multiple racks. It could be configured in multiple ways, but with all these complexities, it is still manageable via a single pane of glass.
