Default Networking Configuration
Using the External Load Balancer
TCP Health Probe
Load Balancer Probes Every 15 seconds
Looks for ACK on socket connect
Traffic stops until ACK received (two failures)
Continues Polling
HTTP Health Probe
Health probe every 15 seconds
HTTP 200 means healthy
Traffic stops until 200 received (two failures)
Continues polling until healthy
Allows deeper inspection into the health of a
web application via custom code.

Virtual Network
DNS options – BYO or Microsoft Azure-provided
Extend your trust boundary – VMs and Cloud Services on the same Network
Bring Your Own DNS
Specify DNS Servers in the Virtual Network
• Hosted in an Azure VM
• External
• On-Premises (with hybrid connection)
VMs are assigned specified DNS at boot.
TIP: if DNS is added after a virtual machine is
running a reboot is required for assignment.

Static IP Addresses
Use Static IP addresses to request a specific IP address be assigned to the
virtual machine.
Addresses available from assigned virtual network subnet.
Will fail if another virtual machine has already been assigned the IP.
Deploy Virtual Machines with Static IP addresses into their own subnets to
avoid conflict with other virtual machines.
Set via PowerShell (Set-AzureStaticVNetIP)

Creating a Virtual Network
Always plan and create the virtual network first
VMs are provisioned into a virtual network (cannot easily move an existing virtual machine to a VNET)
Virtual Network configuration file
Import/Export from the management portal – use as a template
Applies to all VNETs in the selected subscription
Create via Microsoft Azure management portal
Create via PowerShell
get-help azurevnet
Gateway redundancy and availability
Gateway roles in Microsoft Azure has 2 instances (active-passive mode)
A pair of VPN devices can be a redundant (i.e. F5 Big IP) and the RRAS service on
Windows Server is supported in a clustered configuration.
Pricing and SLA

Deploying Globally with Traffic Manager
Traffic Manager – DNS Based Load Balancer
Three Load Balancing Algorithms
Performance, Round Robin, Fail Over
Map your domain name to yourservice.trafficmanager.net with CNAME
contoso.com -> contosotm.trafficmanager.net
Map cloud service URLs in global data centers to Traffic Manager Profile.
contosoeast.cloudapp.net
contosowest.cloudapp.net
Built in HTTP Health Probes for High Availability
Performance
Traffic Manager determines fastest route for the client and returns IP for
the appropriate cloud service.
Round Robin
Traffic Manager returns IPs in a round robin fashion regardless of client
location.
Failover
Traffic Manager always returns the IP address of the
primary cloud service unless it fails a health check.
