Private cloud is a type of cloud computing that delivers similar advantages to the public cloud, including scalability and self-service, but through a proprietary architecture. Unlike public clouds, which deliver services to multiple organizations, a private cloud is dedicated to the needs and goals of a single organization.
As a result, private cloud is best for businesses with dynamic or unpredictable computing needs that require direct control over their environments, typically to meet security, business governance or regulatory compliance requirements.
There are three general cloud deployment models: public, private and hybrid.
A public cloud is where an independent, third-party provider, such as Amazon Web Services (AWS) or Microsoft Azure, owns and maintains computing resources that customers can access the internet. Public cloud users share these resources, a model is known as a multi-tenant environment. Continue reading
At its most basic, a NAS is used largely for storage and sharing files across a network, but the newest devices can do so much more. We help you understand what to look for when shopping for network-attached storage.
A network-attached storage (NAS) device is primarily a centralized repository for data. It differs from a direct-attached storage (DAS) device in that instead of attaching directly to a computer, it attaches to (you guessed it) a network. Most NASes are used largely for storage and for sharing files across a network, but the newest NASes can do so much more. In fact, they can do so many things that shopping for one can be confusing. Here’s what you need to know when selecting network-attached storage.
A NAS is a server. Most NASes can be used as multimedia servers, as most support the UPnP and DLNA protocols. These protocols are for sharing and streaming multimedia files to devices such as gaming consoles, tablets, and phones on a network. NASes are also multifaceted devices that can often be configured as FTP, The Web, e-mail, and print servers. Continue reading
Until recently, PC buyers had very little choice about what kind of storage to get in a laptop or desktop. If you bought an ultraportable, you likely had a solid-state drive (SSD) as the primary drive (C: on Windows, Macintosh HD on a 
Mac). Every other desktop or laptop form factor had a hard disk drive (HDD). Now, you can configure most systems with either an HDD or an SSD, or in some cases both. But how do you choose? We explain the differences between SSDs and HDDs (or hard drives), and walk you through the advantages and disadvantage of both to help you decide.-Hard Disk Drives and Solid State Drives
The traditional spinning hard drive is the basic nonvolatile storage on a computer. That is, information on it doesn’t “go away” when you turn off the system, as is the case with data stored in RAM. A hard drive is essentially a metal platter with a magnetic coating that stores your data, whether weather reports from the last century, a high-definition copy of the original Star Wars trilogy, or your digital music collection. A read/write head on an arm accesses the data while the platters are spinning. Continue reading
