Servers Types - Hyper- V | VM Ware | VDI

 Hyper-V is a hardware virtualization technology built into some editions of Microsoft Windows. It lets you create and run virtual machines (VMs) — essentially “computers inside your computer.”

A virtual machine behaves like a separate PC with its own:

  • Operating system
  • Virtual hard drive
  • RAM
  • CPU allocation
  • Network settings

For example, on one Windows PC you could run:

  • Windows 11
  • Ubuntu Linux
  • Windows Server
    all at the same time using Hyper-V.

What Hyper-V is used for

Common uses include:

  • Testing software safely
  • Running Linux on Windows
  • Learning networking/server administration
  • Creating isolated development environments
  • Malware analysis/sandboxing
  • Running legacy operating systems

How it works

Hyper-V uses a hypervisor, which sits between the hardware and operating systems.

There are two main parts:

  1. Host OS — your main Windows installation
  2. Guest OS — the virtual machines you create

The hypervisor shares your computer’s hardware resources among the VMs.

Hyper-V requirements

Typically requires:

  • 64-bit CPU with virtualization support (Intel VT-x or AMD-V)
  • Hardware virtualization enabled in BIOS/UEFI
  • Windows Pro, Enterprise, or Server editions

Hyper-V is generally not available on Windows Home editions by default.

Main Hyper-V tools

  • Hyper-V Manager — graphical VM management tool
  • Virtual Switch Manager — networking for VMs
  • Checkpoint/Snapshots — save VM state
  • PowerShell integration — automation

Hyper-V vs VirtualBox / VMware

Example

If you want to test Ubuntu without changing your main Windows setup:

  1. Enable Hyper-V
  2. Create a VM
  3. Attach Ubuntu ISO
  4. Install Ubuntu inside the VM

Your real PC remains unchanged.



WHAT IS A VDI 

Virtual Desktop Infrastructure (VDI) stands for Virtual Desktop Infrastructure.

It’s a technology where a user’s desktop environment runs on a central server instead of directly on their physical computer.

Instead of your laptop doing all the work:

  • the desktop runs inside a virtual machine in a data center or cloud
  • your device acts mainly as a screen/keyboard/mouse interface

You connect remotely to that virtual desktop.

Simple idea

With VDI:

Your physical device
→ connects over network/internet
→ to a virtual desktop hosted elsewhere

The virtual desktop can run:

  • Windows 10/11
  • Linux
  • enterprise applications

How Hyper-V relates to VDI

Hyper-V can be used as the virtualization platform underneath a VDI system.

Hyper-V creates and runs the virtual machines, while VDI software manages:

  • user sessions
  • desktop assignment
  • remote access
  • security
  • scaling

Common VDI platforms

  • Citrix Virtual Apps and Desktops
  • VMware Horizon
  • Microsoft Azure Virtual Desktop
  • Nutanix Frame

Why companies use VDI

Centralized management

IT manages desktops from one place.

Better security

Data stays on the server instead of employee laptops.

Remote work

Employees can access office desktops from anywhere.

Lower hardware requirements

Even thin clients or older PCs can access powerful desktops.

Easy maintenance

Updating one image can update many desktops.

Example

A company gives employees:

  • cheap laptops
  • internet access
  • login credentials

When employees log in:

  • they connect to a Windows desktop running in the company’s data center
  • all apps and files stay there

 Azure Site Recovery an earlier tool for migration: Thought purpose built for Disaster Recovery ASR: Azure Site Recovery Yes — Azure Site Recovery (ASR) is commonly used as a migration tool , even though its primary purpose is disaster recovery. How ASR Is Used for Migration Organizations use ASR to perform: Lift-and-shift migrations VMware to Azure migrations Hyper-V to Azure migrations Physical server to Azure migrations ASR replicates workloads continuously from on-premises infrastructure to Azure. During the final cutover, the replicated VM is started in Azure with minimal downtime. Migration Workflow Using ASR Typical Flow Discover on-prem servers Enable replication Continuous data synchronization Test failover (optional) Planned failover/cutover Azure VM becomes production workload This approach minimizes: Downtime Data loss Manual rebuild effort Why ASR Is Popular for Migration ASR vs Azure Migrate Real-World Use Case Example: Company has 200 VMware VMs on-premises.

Azure -- All Networking Components

   1. Virtual Network (VNet) 📌 One-paragraph explanation A Virtual Network (VNet) is the core private networking space in Azure where all cloud resources communicate securely. It is used to isolate workloads, control IP ranges, and create a private environment similar to a traditional data center network but fully software-defined in the cloud. 🔍 Details Where used: Hosting VMs, AKS clusters, databases, internal services Connected services: VM, Load Balancer, Application Gateway, Azure Firewall, Private Endpoint Dependencies: None (foundation component) Purpose in architecture: Acts as the main “network boundary” for all resources 🧩 2. Subnet 📌 One-paragraph explanation A subnet is used to divide a VNet into smaller logical networks so that different layers of an application (web, app, database) can be separated and controlled independently for security and traffic management. 🔍 Details Where used: Tiered architectures (web/app/db layers), microse...

  Kubernetes Core Resources Explained 1. Pods What It Is A Pod is the smallest deployable unit in Kubernetes. It contains one or more containers that share: Network Storage Lifecycle Used For Running application containers Grouping tightly coupled containers together Example A web application container running inside a pod. 2. Deployments What It Is A Deployment manages Pods and ReplicaSets. Used For Rolling updates Application version upgrades Scaling applications Self-healing applications Example Deploying 3 replicas of an NGINX application. 3. ReplicaSets What It Is A ReplicaSet ensures a specified number of pod replicas are always running. Used For High availability Maintaining desired pod count Example Keeping 5 backend pods running at all times. 4. DaemonSets What It Is A DaemonSet ensures one pod runs on every node (or selected nodes). Used For Monitoring agents Log collectors Security agents Example Running Fluentd or Prometheus Node Exporter on all nodes. 5. StatefulSets W...
