Azure Virtual Machines Deep Dive

“Welcome back. Today we're getting hands-on with Azure Virtual Machines. By the end of this video, you'll have created your own VM in Azure, connected to it, and understood how VMs fit into the bigger cloud picture.”

“A virtual machine is a software-based computer running inside Azure's physical servers. It behaves exactly like a real computer — it has its own CPU, RAM, storage, and network interface — but it's virtualized. You choose the OS, install your software, and manage it just like a physical server. The difference is Azure handles all the physical hardware underneath.”

“Azure VMs come in dozens of sizes organized into series. B-series are burstable, cost-effective VMs great for development and testing. D-series are general purpose workhorses. E-series are memory-heavy for databases. And N-series come with GPUs — critical for AI and machine learning workloads, which we'll explore later in this series.”

“Every VM gets an OS disk — that's where Windows or Linux is installed. You can attach additional data disks for your application data. The key thing to understand is disk tiers: Standard HDD is cheapest and slowest, Premium SSD is fast and reliable, and Ultra Disk delivers extreme IOPS for demanding workloads like databases. Always use Managed Disks — Azure handles replication and backups automatically.”

“When you create a VM, it lives inside a Virtual Network — your own private network in Azure. You define subnets within that network, and your VM gets a Network Interface Card connecting it. A Network Security Group acts as a firewall, controlling inbound and outbound traffic. For most demos, we'll assign a public IP so we can connect from our laptops.”

“Time for the demo. I'll walk you through creating a Windows Server VM from scratch in the Azure portal, configuring all the settings we just discussed, and connecting to it via Remote Desktop. Let's go.”

“You've now created and connected to your first Azure VM. You understand sizes, storage tiers, and networking fundamentals. Next video, we'll cover Azure Storage Accounts — Blob, File, Queue, and Table storage — and when to use each. See you there.”
