Deployment services are software-based solutions used to support the implementation and rollout of new applications or infrastructure. They can include hardware or software acquisition tuning, configuration, staging, installation, and interoperability tests.
The benefits of app deployment include enhanced security, simplified management and better insight into user behavior. App deployment simplifies complex tasks that take a lot of time and are costly, like software upgrades.
If your business requires to move servers or install new ones, HP offers a comprehensive range of deployment services that can accelerate the process. From device delivery and staging to installation, setup and data migration Our deployment services can help you get up and running quickly and efficiently and with a minimum of downtime.
Windows Deployment Service – Provides network-based, centralized deployment of operating system to computers running bare metal. It is the successor of Remote Installation Services (RIS). WDS uses disk imaging to install virtually any operating system.
Microsoft Windows Server 2008 R2 or later makes use of the Windows Image Format (WIM), for example creating images that can be used for remote installation. A Windows image contains an environment that is pre-boot and boots the computer and allows it to install the operating system. The administrator can www.deployeveryday.com/running-knative-locally customize and extend the pre-boot environment to perform other tasks, like installing an additional driver.
To make use of WDS the environment must be set up to allow a local network or Internet access. The environment must also have a Windows Deployment Services Server role installed on the server. This includes the DHCP server.
Microsoft provides a variety of tools that can be used for WDS to manage deployment servers, build, create images, and then apply them. These include imagex, dism and the wdsutil. These tools can be utilized on the same server as the WDS server or on separate servers. Imagex is a command-line tool that can create one WIM or a deduplication structure. It can be executed on a network share or mapped drive letter. The wdsutil tool can be used to manage the WDS server without the GUI and to upload images that have been taken to the repository.
Virtual Machines can be created as client machines for creating and testing Windows deployment image. Virtual machines can affect the performance of the Trivial File Transfer Protocol (TFTP) download phase. This is especially important in the event that the virtual machines aren’t capable of handling a complete boot loader.
Multiple WDS servers – Could be used to provide fault tolerance and redundancy. You can deploy one WDS server to manage a lot of WIM images, or you can install multiple WDS servers within networks to increase availability and offer fault tolerance.
A Windows image can be created with ImageX or another third-party tool, and then distributed via the Internet to another WDS server. The image is downloaded to local servers or remote server, or even a Hyper-V virtual machine.
Ron’s supervisor gives him the responsibility of deploying the most recent Windows 7 OS at the branches of the company’s fifty offices. Ron wants to do this remotely, so he doesn’t need to travel to branch locations. However, the company policy states that only one DHCP is allowed on corporate network, and that’s located at the Tooth City Office.
