...Network-attached storage (NAS) is file-level computer data storage connected to a computer network providing data access to a heterogeneous group of clients. NAS not only operates as a file server, but is specialized for this task either by its hardware, software, or configuration of those elements. NAS is often manufactured as a computer appliance, a specialized computer built from the ground up for storing and serving files, rather than simply a general purpose computer being used for the role. All depends how much money you have to spend. The high end commercial stuff is actually where the fastest networking interfaces in the world exist. The way manufacturers make NAS devices can be classified into three types: Computer based NAS—Using a computer (Server level or a personal computer), installs FTP/SMB/AFP... software server. The power consumption of this NAS type is the largest, but its functions are the most powerful. Some large NAS manufacturers like Synology, QNAP and ASUStor make these types of devices. Max FTP throughput speed varies by computer CPU and amount of RAM. Embedded system based NAS—Using an ARM, MIPS... embedded system and RTOS to run a NAS server. The power consumption of this NAS type is fair, and functions in the NAS can fit most end user requirements. Marvell, Oxford, and Storlink make chipsets for this type of NAS. Max FTP throughput varies from 20 MB/s to 120 MB/s. ASIC based NAS—Provisioning NAS through the use of a single ASIC chip, using hardware...

...charges are applied on how much you use them. With cloud services you can connect at home, work or on the go via a laptop, desktop, smartphone or other handheld devices. Widespread cloud computing is made possible by the Internet, and this is the most common way of accessing cloud resources. The basic cloud computing model is shown below. Servers, storage, applications, and services are accessed via a common network. They are shared between organizations, and accessed by users or applications. The users may be members of the organizations working on-premise, remote workers, customers, or members of the general public. Cloud computing has three service models. These are the basic kinds of service that cloud service providers provide. They are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). [1] Infrastructure as a Service (IaaS) is a cloud model which allows organizations to outsource computing equipment and resources such as servers, storage, networking as well as services, such as load balancing and content delivery networks. The IaaS provider owns and maintains the equipment while the organization rents out the specific services it needs, usually on a "pay as you go" basis. Platform as a Service (PaaS) is a cloud model designed for software developers. PaaS is used to develop web and mobile applications using components that are maintained by the service provider, including programming languages, application servers and databases...

Featuring Internet Information Services (IIS) 7.5 and designed exclusively as an Internet-facing server. (Microsoft, 2010) Top 10 New Features in Windows Server 2008 #10: The self-healing NTFS file system: Ever since the days of DOS, an error in the file system meant that a volume had to be taken offline for it to be remedied. In WS2K8, a new system service works in the background that can detect a file system error, and perform a healing process without anyone taking the server down. #9: Parallel session creation: "Prior to Server 2008, session creation was a serial operation," Russinovich reminded us. "If you've got a Terminal Server system, or you've got a home system where you're logging into more than one user at the same time, those are sessions. And the serialization of the session initialization caused a bottleneck on large Terminal Services systems. So Monday morning, everybody gets to work, they all log onto their Terminal Services system like a few hundred people supported by the system, and they've all got to...
