Azure Image Builder - Simply Explained

Description

Azure Image Builder solves a problem that becomes increasingly difficult as environments grow: manually creating and maintaining standardized virtual machine images. The traditional process often starts with a clean VM. An administrator installs Windows updates, applications, monitoring agents, security tools, certificates, and configuration changes. The VM is tested, generalized, and finally captured as an image. That approach can work, but it depends heavily on people remembering every step. When updates or requirements change, the process has to be repeated, and small differences can quickly appear between supposedly identical images. Azure Image Builder replaces that manual routine with a repeatable Azure-based process. ㅤWHAT IS AZURE IMAGE BUILDER?Azure Image Builder is an Azure service that creates customized virtual machine images from instructions you define. You begin with a known source image, define the changes that should be made, and Azure produces a new customized image. The result becomes a standardized starting point for future virtual machines rather than requiring administrators to configure every new VM manually. ㅤSTART WITH A KNOWN SOURCE IMAGEAzure Image Builder can begin with Windows or Linux images from Azure Marketplace. That could include Windows Server, Windows 11, Ubuntu, or another supported operating system. Organizations can also start with images they have already created, including existing company images or images stored in Azure Compute Gallery. This means you don't necessarily need to rebuild everything from scratch whenever the image changes. ㅤIMAGE BUILDER DOES NOT CREATE YOUR PRODUCTION VMSThe name can create some confusion. Azure Image Builder isn't primarily responsible for creating the production VMs that users or applications eventually consume. It creates the prepared image first. Afterward, organizations can create one VM, ten VMs, or potentially much larger deployments from that finished image. Think of Image Builder as creating the approved master copy from which futu
