This specific type of storage is often supported by a Network Attached Storage (NAS) server. Many applications need to access and share the same files, making file storage the natural choice. The drawback is that the more data you add, the more tedious it becomes to sift through each individual drawer and folder. To quickly locate your file (data), you would first need to be made aware of which drawer and which folder within said drawer you need to look for. Within a filing cabinet, you have specific drawers, and within those drawers, you have particular folders. The hierarchical nature of file storage renders it very similar to its real-life counterpart, the filing cabinet. It’s also an excellent solution for companies looking for cloud-based file sharing. It uses metadata and directories to organize files, which makes it an easy-to-understand solution for those looking to store large data sets. Simply put, file storage provides one centralized location for your enterprise to store data. File StorageĪt the simpler end of the cloud-based storage solution is file storage. They can also be used to import existing data stores for analytics, backup, or archival purposes. Object storage solutions like Amazon Simple Storage Service (Amazon S3) are ideal for building modern applications from scratch that require scale and flexibility. But unlike hunting for a fish in a real lake, the water is transparent, and you have a bird’ s-eye view of each fish’s identifying features (metadata), so you know exactly where to go to grab the fish you want.īecause object storage uses one huge storage house or “pool,” it is easily scalable, and the improved metadata characteristics mean this solution lends itself to many applications built in the cloud. Each fish is an “object,” and you, like a hunting eagle, can pick out and retrieve whichever fish you like. It’s perhaps best to envisage object storage as looking at a vast lake full of fish. These objects are not ingrained in files and other folders instead, all of the relevant metadata pertaining to the object are combined to form a unique identifier. ![]() Rather than breaking up data into blocks and then storing those blocks as separate pieces, each with a unique identifier, object storage throws different data units (“objects”) into one large storage pool. EBS Volumes on AWS are decoupled from the servers they are attached to which means that you can move an EBS volume from one server to another, for example, if the first server fails. ![]() The added advantage of block storage is that the data is highly redundant across the blocks and storage volumes, meaning if any component suffers an outage, the data can still be retrieved.īlock-based cloud storage solutions like Amazon Elastic Block Store (EBS) are provisioned with each virtual server and offer the advantage of providing the ultra-low latency required for high-performance workloads. It’s similar in many ways to direct-attached storage (DAS) and is often accessed via a Storage Area Network (SAN). The same software or another independent solution then handles data retrieval by using that metadata “address” to locate and organize the blocks of data into complete files.īlock storage can be an excellent solution for those running large databases or ERP systems that require low latency storage for each host. When it comes to management and organization of block storage, another software program is required to administer which blocks go where. Each block is assigned a unique address, but that is the only metadata attached to each one. Block Storageīlock storage works by saving data to the storage media in fixed-sized chunks, otherwise known as blocks. Let’s start with the first on the list, block storage. Each needs to be assessed on their own merits before deciding which option presents the best fit. ![]() Block, object, and file storage all offer a different cloud-based solutions that address different business use cases. With an increasing shift toward cloud storage, it’s vital that enterprises, and those that build systems within those companies, understand the architectural differences of the three predominant cloud storage types. Storage is a significant consideration for any business.
