When resumed, applications and OS sessions continue exactly where they left off, unlike a full reboot. Key Benefits Supported VM sizes VM sizes with up to 64-GB RAM from the following General Purpose VM…
Read More →Linux VM hibernation in Microsoft Azure enables virtual machines to pause execution while preserving the full in-memory state to disk. When the VM is started again, the Linux OS resumes exactly from where it left off—processes, applications, and sessions intact. This feature is designed for cost optimization and fast resume for stateful Linux workloads. Supported…

This helps keep virtual machines and scale sets secure, stable, and compliant. It applies to: Prerequisites Before enabling automatic upgrades: Supported extensions To check if your extensions are supported for automatic upgrade, view Automatic…
Read More →Tags are metadata elements that you can apply to Azure resources to help categorize and organize them according to business, operational, or governance needs. A tag is a key–value pair. For example, to track deployment environments, you might add a tag with the key Environment and the value Production, forming Environment = Production. This article…
Read More →There are several scenarios where you may need to move Azure IaaS virtual machines (VMs) from one region to another—for example, to improve reliability and availability, enhance manageability, or meet governance requirements. Azure Site Recovery (ASR) enables you to replicate and move Azure VMs to a secondary region. In this you will learn how to:…
Read More →Availability Zones in Azure provide enhanced resiliency by protecting applications and data from datacenter-level failures. Each Availability Zone consists of one or more datacenters with independent power, cooling, and networking. Azure ensures high availability by offering a minimum of three physically separate zones in every zone‑enabled region. This physical isolation within a region helps safeguard…
