![]() Cloud NAS is commonly used for web serving, content management, data analytics, data backups, archiving, streaming content, and software development. With cloud NAS, a user or business can easily store and access data from cloud storage with the same ease and convenience as a local NAS device in the data center or desktop. It uses cloud computing to provide expandable storage as a central source for storage while still providing enterprise NAS features, such as file access, sharing, and collaboration. System available features depend upon the NAS chip and firmwareĪ cloud NAS works like the legacy, on-premises NAS, but it is a virtual appliance designed to work with and leverage cloud-based storage.Requires knowledge of computer networking.Operational burden and drain IT budgets and resources.Latency for video or multiple large files.Inability to deliver performance at scale.NAS requires the setup and configuration of hardware and software, and the device needs to be connected to the network. The resulting inadequate performance can create latency and poor user experiences. I/O contention can occur when too many users access the system at the same time with requests. NAS devices must serve multiple client systems across a network, including users and other applications. Unlike cloud services, maintenance and repairs must be handled directly, which requires IT expertise. NAS deployments have far fewer available. Simple NAS stores data on a remote disk, but if data availability and protection from data loss in the event of a disk failure are requirements, it will not suffice.Ĭloud deployments consist of thousands of servers, which can be used for failover. Wide array of systems and sizes availableīecause data stored on a NAS device is backed up on-premises, if the NAS device breaks down, is stolen, or is destroyed (e.g., in a fire), the stored files could be lost.Automatic backup to other devices and the cloud. ![]() And, since they are so small, they are easy to transport if they need to be brought to a service provider for repair. This makes them easily accessible for maintenance or repairs. Most NAS devices are about the size of a toaster, making them easy to store-at users’ workstations or storage rooms. This can be done in several ways, including adding a new hard disk or solid-state media, adding a new shelf of drives, or adding a whole new NAS system and coupling it with the installed NAS devices using coupling software. NAS can quickly and easily scale out to meet increased capacity demands. While NAS requires an upfront investment, no more expenditure is needed beyond maintenance and repair. Assuming proper security protocols are followed, this can mean a higher level of security than with a cloud provider. With NAS, all aspects of security are handled in-house. NAS Features, Benefits, and Drawbacks Features and Benefits of NAS Devices ![]() Testing and developing web-based and server-side web applications.Storing images and videos that require frequent access.Serving email, multimedia files, databases, and print jobs.Hosting messaging, server-based, open-source applications, and virtual desktop infrastructure.Backup target, using a NAS array for disaster recovery.Several ways that NAS is used in enterprise environments include: NAS devices can also be clustered together for scale-out storage to support heavy workloads. In enterprise environments, NAS devices have three to five, and sometimes more, drive bays. NAS devices usually contain a minimum of two drive bays, although single-bay systems are available for noncritical data. NAS consolidates storage, but can expand storage capacity by using more and/or larger disks. NAS connects to a wireless router making it easy for users to access files from any desktop or mobile device with a network connection.īefore the availability of NAS, enterprises had to configure and manage hundreds or even thousands of file servers to meet storage requirements. Each NAS server resides on the network as an independent node and is defined by a unique IP address. Most NAS devices are configured and managed with a browser-based utility and do not have a keyboard or display. The growing demand for file-sharing and storage solutions has increased the options available for on-premises NAS devices and cloud solutions.
