4. What is Cloud Computing?
Cloud computing is a model for enabling ubiquitous,
convenient, on-demand network access to a shared pool of
configurable computing resources (e.g., networks, servers,
storage, applications, and services) that can be rapidly
provisioned and released with minimal management effort or
service provider interaction.

5. Service Models of Cloud Computing

6. Azure IaaS
• It is responsible for providing Azure Virtual Machines, along
with Azure Virtual Network.
• Networking, Compute, Storage and Hypervisors are managed
by Microsoft.
• Starting from the Operating System, everything is managed by
you. Things like applications, data, etc.

7. Azure Resource Manager
• The Azure Resource Manager is the service used to provision
resources in your Azure subscription.
• It enables you to work with the resources in your solution as a
group.
• It provides security, auditing, and tagging features to help you
manage your resources after deployment.
• It provides a consistent management layer to perform tasks
through Azure PowerShell, Azure CLI, Azure portal, REST API,
and client SDKs.

8. Azure Resource Manager
Terminologies:
• Resource
• Resource Group
• Resource Provider
• Resource Manager Template
• Declarative Syntax

9. Azure Virtual Machines Components
• Virtual Machine.
• VHD Files
• Image
• Disk
• Virtual Network
• Subnet
• IP Address
• Load Balancer
• Network Security Group

10. ARM Resource Providers for a VM

11. Azure Virtual Machine Series
• A-Series - Entry-level economical VMs for dev/test
• B-Series - Economical burstable VMs
• D-Series - General Purpose Compute
• E-Series - Optimised for in-memory hyper-threaded
applications
• F-Series - Compute optimised virtual machines
• G-Series - Memory and storage optimised virtual machines
• H-Series - High performance virtual machines
• L-Series - Storage optimised virtual machines
• M-Series - Largest memory optimised virtual machines
• N-Series – GPU enabled virtual machines

12. Billing and VM State
You will be billed on a per-minute basis for all the VMs that are
in running state.
There is a direct relationship between the VM’s status and
billing:
• Running - The VM is on and running normally (billable).
• Stopped - The VM is stopped but still deployed to a physical
host (billable)
• Stopped (Deallocated) - The VM is not deployed to a physical
host (not billable).

13. LIVE DEMO
• Create a VM using portal
• Create a VM using PowerShell
• Create a VM using Azure CLI
• Create a VM using ARM template
• Connect to a Windows Virtual Machine (RDP and PowerShell)
• Connect to a Linux Virtual Machine (SSH)

14. Availability Sets
• Availability Sets ensure that the Azure virtual machines are
deployed across multiple isolated hardware nodes in a cluster.
• Only a sub-set of your virtual machines are impacted in case
of a hardware/software failures.
• Virtual Machines are deployed across multiple fault domains
and update domains.
• To meet the 99.95% SLA, VMs should be deployed in
Availability Sets, except in the case of Premium Storage.

15. Availability Sets
• Fault domains define the group of virtual machines that share
a common power source and network switch.
• Update domains indicate groups of virtual machines and
underlying physical hardware that can be rebooted at the
same time.

16. Availability Sets using Managed Disks

17. Availability Sets using Unmanaged Disks

18. Azure Virtual Machine Scale Sets
Azure virtual machine scale sets let you create and manage a
group of identical, load balanced VMs
Benefits:
• Easy to create and manage multiple VMs
• Provides high availability and application resiliency
• Allows your application to automatically scale as resource
demand changes
• Works at large-scale

19. LIVE DEMO
• Deploy two VMs in an Availability Sets
• Create a Virtual Machine Scale Set

20. Azure VM Agent
• The VM Agent has a primary role in enabling and executing
Azure virtual machine extensions.
• Installed by default on any Windows VM deployed from Azure
Marketplace.
• Can be installed manually on custom or uploaded images.
• Azure Linux Agent (waagent) manages Linux & FreeBSD
provisioning, and VM interaction with the Azure Fabric
Controller.

21. Azure VM Extensions
Azure virtual machine (VM) extensions are small applications
that provide post-deployment configuration and automation
tasks on Azure VMs.
Common VM Extensions are:
• Custom Script Extension for Windows
• DSC Extension for Windows
• Azure Diagnostics Extension
• Azure VM Access Extension

22. LIVE DEMO
• Execute a custom script extension against Windows VM
