Network-attached Storage
Network-attached storage (NAS) is a file-level computer data storage server connected to a computer network providing data access to a Heterogeneous computing, heterogeneous group of clients. In this context, the term "NAS" can refer to both the technology and systems involved, or a specialized computer appliance device unit built for such functionality – a ''NAS appliance'' or ''NAS box''. NAS contrasts with block-level storage, block-level storage area networks (SAN). Overview A NAS device is optimised for file server, serving files either by its hardware, software, or configuration. It is often manufactured as a computer appliance a purpose-built specialized computer. NAS systems are networked appliances that contain one or more hard disk drive, storage drives, often arranged into logical disk, logical, redundant storage containers or RAID. Network-attached storage typically provide access to files using network file sharing protocols such as Network File System (protocol), ...

Linux
Linux ( ) is a family of open source Unix-like operating systems based on the Linux kernel, an kernel (operating system), operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically package manager, packaged as a Linux distribution (distro), which includes the kernel and supporting system software and library (computing), libraries—most of which are provided by third parties—to create a complete operating system, designed as a clone of Unix and released under the copyleft GPL license. List of Linux distributions, Thousands of Linux distributions exist, many based directly or indirectly on other distributions; popular Linux distributions include Debian, Fedora Linux, Linux Mint, Arch Linux, and Ubuntu, while commercial distributions include Red Hat Enterprise Linux, SUSE Linux Enterprise, and ChromeOS. Linux distributions are frequently used in server platforms. Many Linux distributions use the word "Linux" in their name, but the Free ...

Kernel-based Virtual Machine
Kernel-based Virtual Machine (KVM) is a free and open-source virtualization module in the Linux kernel that allows the Kernel (operating system), kernel to function as a hypervisor. It was merged into the Mainline Linux, mainline Linux kernel in version 2.6.20, which was released on February 5, 2007. KVM requires a processor with hardware virtualization extensions, such as Intel VT or AMD-V. KVM has also been ported to other operating systems such as FreeBSD and illumos in the form of loadable kernel modules. KVM was originally designed for x86 processors but has since been porting, ported to IBM ESA/390, ESA/390, PowerPC, IA-64, and ARM architecture, ARM. The IA-64 port was removed in 2014. KVM supports hardware-assisted virtualization for a wide variety of guest operating systems including BSD, Solaris (operating system), Solaris, Microsoft Windows, Windows, Haiku (operating system), Haiku, ReactOS, Plan 9 from Bell Labs, Plan 9, AROS Research Operating System, AROS, macOS, ...

Hypervisor
A hypervisor, also known as a virtual machine monitor (VMM) or virtualizer, is a type of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a ''host machine'', and each virtual machine is called a ''guest machine''. The hypervisor presents the guest operating systems with a virtual operating platform and manages the execution of the guest operating systems. Unlike an emulator, the guest executes most instructions on the native hardware. Multiple instances of a variety of operating systems may share the virtualized hardware resources: for example, Linux, Windows, and macOS instances can all run on a single physical x86 machine. This contrasts with operating-system–level virtualization, where all instances (usually called ''containers'') must share a single kernel, though the guest operating systems can differ in user space, such as different Linux distributions with the sam ...

Elastic Block Storage
Amazon Elastic Block Store (EBS) provides raw block-level storage that can be attached to Amazon EC2 instances and is used by Amazon Relational Database Service (RDS). It is one of the two block-storage options offered by AWS, with the other being the EC2 Instance Store. Amazon EBS provides a range of options for storage performance and cost. These options are divided into two major categories: SSD-backed storage for transactional workloads, such as databases and boot volumes (performance depends primarily on IOPS), and disk-backed storage for throughput intensive workloads, such as MapReduce and log processing (performance depends primarily on MB/s). Use case In a typical use case, using EBS would include formatting the device with a filesystem and mounting it. EBS supports advanced storage features, including snapshotting and cloning. As of September 2020, EBS volumes can be up to 2 TiB in size using the MBR partitioning scheme, and up to 16 TiB using the GPT partitioning ...

Amazon Machine Image
An Amazon Machine Image (AMI) is a special type of virtual appliance that is used to create a virtual machine within the Amazon Elastic Compute Cloud (EC2). It serves as the basic unit of deployment for services delivered using EC2. __TOC__ Overview Like all virtual appliances, the main component of an AMI is a read-only filesystem image that includes an operating system (e.g., Linux, Unix, or Windows) and any additional software required to deliver a service or a portion of it. An AMI includes the following: * A template for the root volume for the instance (for example, an operating system, an application server, and applications) * Launch permissions that control which AWS accounts can use the AMI to launch instances * A block device mapping that specifies the volumes to attach to the instance when it's launched The AMI filesystem is compressed, encrypted, signed, split into a series of 10 MB chunks and uploaded into Amazon S3 for storage. An XML manifest file stores in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amazon Web Services
Amazon Web Services, Inc. (AWS) is a subsidiary of Amazon.com, Amazon that provides Software as a service, on-demand cloud computing computing platform, platforms and Application programming interface, APIs to individuals, companies, and governments, on a metered, pay-as-you-go basis. Clients will often use this in combination with elasticity (system resource), autoscaling (a process that allows a client to use more computing in times of high application usage, and then scale down to reduce costs when there is less traffic). These cloud computing web services provide various services related to networking, compute, storage, middleware, Internet of things, IoT and other processing capacity, as well as software tools via AWS server farms. This frees clients from managing, scaling, and patching hardware and operating systems. One of the foundational services is Amazon Elastic Compute Cloud (EC2), which allows users to have at their disposal a Virtualization, virtual Computer clus ...
