Some Basics:Cloud Service:• Grants a public IP and DNS per CS.• Contains your Virtual Machines(VMs)
Virtual Machine:• Hosts your service/application• Multiple VMs can be under one cloud service.
Why do we need Load BalancerLoad balancing, by its very nature, is the solution for more than one problem such as:
1. Traffic Redundancy2. BCP Failover3. User Experience
What is Azure Traffic ManagerThree Load Balancing AlgorithmsPerformance, Round Robin, Fail Over
Map your domain name to yourservice.trafficmanager.net with CNAMEcontoso.com -> contosotm.trafficmanager.net
Map cloud service URLs in global data centers to Traffic Manager Profile.contosoeast.cloudapp.netcontosowest.cloudapp.net
Built in HTTP Health Probes for High AvailabilityCan be used outside Azure (For example: Your “On Premise”)
Round Robin Profile

Request for contoso.comLocation Portland, OR
Response with IP for contosoeast.cloudapp.net
Health Probes
Traffic Manager Returns the Next IPCould be West or East
Traffic Manager returns IPs in a round robin fashion regardless of client location.

Traffic Manager always returns the IP address of the primary cloud service unless it fails a health check.

Traffic Manager Calculates Hops…
Traffic Manager determines fastest route for the client and returns IP for the appropriate cloud service.
Demo
Performance
PowerShell DemoAdd the azure account to PowerShell
Add-azureaccount
Choose the correct subscription Select-AzureSubscription
PowerShell DemoCreate a new azure traffic manager with the following properties:
Name: SDP-TM-PerformanceDomain Name: SDP-TM-Performance.trafficmanager.netLoad Balancing method: PerformanceMonitor Protocol: HttpMonitor Port: 80Relative path to monitor: /iis85.jpgTTL: 30 Seconds
PowerShell DemoNew-AzureTrafficManagerProfile -Name "SDP-TM-Performance" -DomainName "SDP-TM-Performance.trafficmanager.net" -LoadBalancingMethod "Performance" -MonitorProtocol "Http" -MonitorPort 80 -MonitorRelativePath "/iis85.jpg" -Ttl 30
PowerShell DemoCreate a variable named "TMProfile" to contain the information about the Traffic manager profile we created.
$TMProfile = Get-AzureTrafficManagerProfile -name "SDP-TM-Performance"
PowerShell DemoUse the variable in order to add our first and second endpoints to the traffic manager, plus saving them using the "Set-AzureTrafficManagerProfile" cmdlet
Add-AzureTrafficManagerEndpoint -TrafficManagerProfile $TMProfile -DomainName "SDP-EUS-CS01.cloudapp.net" -Status "Enabled" -Type "CloudService" | Set-AzureTrafficManagerProfile
Add-AzureTrafficManagerEndpoint -TrafficManagerProfile $TMProfile -DomainName "SDP-WE-CS01.cloudapp.net" -Status "Enabled" -Type "CloudService" | Set-AzureTrafficManagerProfile
PowerShell Demo How it all looks:
New-AzureTrafficManagerProfile -Name "SDP-TM-Performance" -DomainName "SDP-TM-Performance.trafficmanager.net" -LoadBalancingMethod "Performance" -MonitorProtocol "Http" -MonitorPort 80 -MonitorRelativePath "/iis85.jpg" -Ttl 30
$TMProfile = Get-AzureTrafficManagerProfile -name "SDP-TM-Performance"
Add-AzureTrafficManagerEndpoint -TrafficManagerProfile $TMProfile -DomainName "SDP-EUS-CS01.cloudapp.net" -Status "Enabled" -Type "CloudService" | Set-AzureTrafficManagerProfile
Add-AzureTrafficManagerEndpoint -TrafficManagerProfile $TMProfile -DomainName "SDP-WE-CS01.cloudapp.net" -Status "Enabled" -Type "CloudService" | Set-AzureTrafficManagerProfile
Other Clouds Solution:AWS
• No single solution – combination of Route 53(DNS) and Elastic load balancing.
• Cannot be used for services not covered by AWS
Google Cloud
• No actual solution: Http(s) Load Balancing or Region Load balancing.• Cannot be used for services not covered by Google
Cloud-based CDNs/ADCs:• Cloudflare – Performance based only. No actual load balancing• Incapsula – Failover, performance, Round-robin• Akamai – Failover, performance, weighted
In this session we learned:1. You learned the basics of the cloud.2. What is Load Balancer3. What is Azure Traffic Manager4. What kind of profiles I can use with Traffic Manager.5. What is the differences between other cloud service providers in terms of load balancing.
