Virtual Machine Availability

Availability considerations
28
• Paired regions
• Availability sets
• scale sets
• Availability zones

Maintenance for VM in Azure
29
Maintenance that doesn't require a reboot
Live migration
Azure platform starts live migration:
• Planned maintenance
• Hardware failure
• Allocation optimizations

Maintenance for VM in Azure
30
Maintenance that requires a reboot
• Notified in advance
Planned maintenance phases:
• Self-service phase – 35 days
• Scheduled maintenance phase

Availability Sets
31
• Fault Domain:
Clusters within a
region (Up to 3)
• Update Domains:
Updates and patches
to clusters (Up to 20)

Scale Up or Down - Vertical
32
• Increase or decrease
configuration of
same server

Scale Out or In - Horizontal
33
Increase or decrease instance count

Scale sets
34
• Group of identical VMs
• Automatically increase or decrease
Instances
• Centrally manage & configure a large
number of VM
• Support Azure load balancer & Azure
Application Gateway
• Max 1,000 VM instances or 600
custom image
Demand
Demand

Availability Zones
35
• Physically separate
locations within an Azure
region
• Minimum of three separate
zones in all enabled
regions
• Zone-redundant services

Question 2
For Virtual machine Scale Set, Scale Out and Scale Up
are same things.
a) True
b) False
36

Question 2
For Virtual machine Scale Set, Scale Out and Scale Up
are same things.
a) True
b) False
37

Question 3
Deploying VM in Availability zone will provide
redundancy in case of datacenter failure ?
a) True
b) False
38

Question 3
Deploying VM in Availability zone will provide
redundancy in case of datacenter failure ?
a) True
b) False

Virtual Machine Extensions

Azure VM Extension
41
• Provide post-deployment
configuration and automation
tasks
• choice of first and third party
extensions
• Custom Script extension
• PowerShell Desired State
Configuration (DSC)

Break
42

Demo
• Deploy virtual machine in Availability sets
• configure networking option like changing dynamic
IP to Static
• Adding additional data disk
• Install Extension and Custom Script option.
• Deploy zone-resilient Azure virtual machine scale
sets
• Scale out scale set based on CPU utilisation
