Reverse Proxy: A reverse proxy is a server that sits in front of web servers and forwards client (e.g. web browser) requests to those web servers. Reverse proxies are typically implemented to help increase security, performance, and reliability. A reverse proxy server is an intermediate connection point positioned at a network’s edge. It receives initial HTTP connection…
What is the difference between running and saved configuration on NetScaler? A: A running configuration refers to the configuration currently running on a NetScaler system. The running configuration on a NetScaler can be seen by issuing the show ns runningconfig command in the Command Line. A saved configuration shows the commands that have been issued through the NetScaler…
Subnet – is a range of IP addresses determined by part of an address (often called the network address) and a subnet mask (netmask). For example, if the netmask is 255.255.255.0 (or /24 for short), and the network address is 192.168.10.0, then that defines a range of IP addresses 192.168.10.0 through 192.168.10.255. Shorthand for writing…
A collection of virtual hardware that creates a standard x86 or x64 enviornment that allows for the installation of a supported guest operating system. A virtual machine is a software computer that, like a physical computer, runs an operating system and applications. The virtual machine is comprised of a set of specification and configuration files…
A LAN is a local area network and is defined as all devices in the same broadcast domain. If you remember, routers stop broadcasts, switches just forward them. What is a VLAN? vlan is a logical configuration of a network on switch port to segment IP traffic. Using vLans reduce h/w needs by allowing a…
Thin provisioning (TP) is a method of optimizing the efficiency with which the available space is utilized in storage area networks (SAN). TP operates by allocating disk storage space in a flexible manner among multiple users, based on the minimum space required by each user at any given time. In the conventional storage provisioning model, also known as fat…
What is VDI? VDI stands for Virtual Desktop Infrastructure, using software to virtualize desktops, then deliver that user experience centrally. Instead of users storing their OS, desktop personality and data on individual laptops or desktops, VDI enables desktop data to run centrally on servers maintained by IT admins, and just accessed locally via a traditional…
Desktop virtualization, often called client virtualization, is a virtualization technology used to separate a computer desktop environment from the physical computer. Desktop virtualization is considered a type of client-server computing model because the “virtualized” desktop is stored on a centralized, or remote, server and not the physical machine being virtualized. Desktop virtualization “virtualizes desktop computers”…
Server virtualization is the partitioning of a physical server into smaller virtual servers to help maximize your server resources. In server virtualization the resources of the server itself are hidden, or masked, from users, and software is used to divide the physical server into multiple virtual environments, called virtual or private servers. This is in…
