Azure Compute Gallery in Azure allows users to manage and share VM images effectively across subscriptions and regions.The gallery serves as a central repository for storing images and streamlines consistent environment deployment.Prerequisites for creating an Azure Compute Gallery include an active Azure subscription and understanding of VMs.Step 1 involves creating the Azure Compute Gallery by providing necessary details like subscription, resource group, and region.Step 2 focuses on preparing the VM for image capture, ensuring it is in the correct state with required configurations.The specialized state of a VM involves unique configurations, applications, and data, necessary for specific deployments.Specialized VMs are tailored for environments requiring specific settings, while generalized VMs remove unique configurations for reuse.Step 3 covers capturing the specialized VM image by naming it, selecting the Compute Gallery, and confirming its specialized state.Generalizing a VM is recommended for creating reusable, standardized images for scaling purposes.Step 4 enables users to use the captured image from Azure Compute Gallery to deploy new VMs, either in the same region or across regions.
