How to avoid IP changes?

To avoid IP changes in Azure, switch resource IP allocations from Dynamic to Static in the network configuration settings. For VMs, set the Public IP address to Static to keep it after reboots. For App Services, use App Service Environments (ASE) for dedicated, permanent IP addresses.

what is windows Admin center and usages ?

Windows Admin Center is a free, browser-based, locally deployed application from Microsoft for managing Windows Servers, clusters, hyper-converged infrastructure, and Windows 10/11 PCs. It acts as a modern, unified evolution of MMC (Microsoft Management Console) and Server Manager. It provides a single pane of glass to manage on-premises, hybrid, and Azure infrastructure without needing cloud connectivity.

What is NIC card?

n Azure Network Interface Card (NIC) is a fundamental, software-defined networking component that connects a virtual machine (VM) to a virtual network (VNet), enabling communication with internet, Azure, and on-premises resources. It acts as the virtualized network adapter, holding private/public IP addresses, and is required for a VM to function.

Auto shutdown usage and benefits?

Azure Auto-shutdown reduces costs and saves energy by automatically turning off Virtual Machines (VMs) at scheduled times, typically used for non-production, development, or test workloads. It ensures VMs are deallocated—ceasing compute charges—and offers notifications, preventing unnecessary expenses from forgotten running VMs.

what is Extension and its usage?

Azure Extensions are small, specialized applications that provide post-deployment configuration, automation, and management capabilities to Azure Virtual Machines (VMs). They are crucial for automating tasks like software installation, antivirus protection, security, and monitoring, enabling customization without needing to log in to the VM directly.
