Microsoft Azure Cloud Enterprise Exchange 2016 deployment 16-Configure Traffic Manager

In this section, we use Azure traffic Manager to load balance the primary secondary site, such as the red box:

With Azure traffic Manager (traffic manager), you can assign user traffic to different data centers across the azure world. Traffic Manager support for service endpoints includes Azure virtual machines, Web applications, and cloud services, and also supports external non-azure Web sites.

To load balance cloud services distributed across different data centers around the world, you can direct incoming traffic to the nearest service. Although "recent" may correspond directly to geographic distances, it may also correspond to locations that serve requests with minimal lag. Use the performance load balancing method to distribute based on location and lag, but not on real-time changes in the network configuration or load.

The performance load Balancing method finds the source of the traffic and routes it to the nearest cloud service, looking for "recent" access nodes, such as automatically finding the best link to access the Exchange front-end server role.

Both Azure traffic manager and azure load balancer can configure load balancing, so what's the difference between traffic manager and azure load balancer?

The following table lists some of the differences:

Type	Azure Load Balancer	Azure Traffic Manager
Implementation method	Based on Layer 4	Based on DNS
End point	Azure virtual machines, cloud service instances	Azure virtual machines, cloud services, web apps, external endpoints
Network support	can support the Internet or the internal network	Only Internet Enabled
Monitoring	Through the probe	by Http/https GET
Agreement	Udp/tcp	Http/https
Computational models	Use 5-tuple (source IP, source port, destination IP, destination port, protocol type)	Cookie-based

Next we'll configure Azure traffic manager

1. First we need to create an Exchange sub-site

Since we've explained in detail the process of creating a primary site, it's easy to go through the process

A. Create a new US site domain-controlled VM and set up a static IP

B. Creating a US site and setting up a replication link

C. Promotion to a domain controller

D. Install the US site Exchange, the configuration here first omitted

650) this.width=650; "height=" 249 "title=" clip_image008 "style=" Border-top:0px;border-right:0px;background-image: none;border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "Alt=" clip_image008 "src=" http://s3.51cto.com/wyfs02/M02/84/05/wKioL1eDb57Cje8GAABILD6u9AY038.png "border=" 0 "/>

E. Configure the endpoint, open the public network port

650) this.width=650; "height=" 315 "title=" clip_image009 "style=" Border-top:0px;border-right:0px;background-image: none;border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "Alt=" clip_image009 "src=" http://s3.51cto.com/wyfs02/M02/84/05/wKioL1eDb5_CSXcxAAAud8G6ZR8042.png "border=" 0 "/>

2. Configure Azure Traffic Manager

Now to Azure Classic Portal Select Create Process Manager, define DNS prefix and load balancing algorithm you, here Select Performance

650) this.width=650; "height=" 212 "title=" clip_image011 "style=" Border-top:0px;border-right:0px;background-image: none;border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "Alt=" clip_image011 "src=" http://s3.51cto.com/wyfs02/M00/84/05/wKioL1eDb5_z2UmtAABMUXoM2Og323.jpg "border=" 0 "/>

Once created, we choose to add an endpoint.

650) this.width=650; "height=" 124 "title=" clip_image013 "style=" Border-top:0px;border-right:0px;background-image: none;border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "Alt=" clip_image013 "src=" http://s3.51cto.com/wyfs02/M02/84/06/wKiom1eDb6DiUSXxAAA7D-yBwvU136.jpg "border=" 0 "/>

Select an Exchange cloud service for JP and US two sites

650) this.width=650; "height=" 394 "title=" clip_image014 "style=" Border-top:0px;border-right:0px;background-image: none;border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "Alt=" clip_image014 "src=" http://s3.51cto.com/wyfs02/M00/84/06/wKiom1eDb6CRg0baAABXteZ7Ei0945.png "border=" 0 "/>

After the creation is complete, we configure the monitoring path

Because the traffic manager needs to get the correct return value for HTTP OK to assume that the server is healthy, we create a new healthcheck.htm file in response to this value under OWA.

650) this.width=650; "height=" 308 "title=" clip_image015 "style=" Border-top:0px;border-right:0px;background-image: none;border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "Alt=" clip_image015 "src=" http://s3.51cto.com/wyfs02/M01/84/05/wKioL1eDb6DSpRtkAAAaxJ666wI489.png "border=" 0 "/>

To create a response file under the EX Server OWA path

650) this.width=650; "height=" 241 "title=" clip_image016 "style=" Border-top:0px;border-right:0px;background-image: none;border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "Alt=" clip_image016 "src=" http://s3.51cto.com/wyfs02/M01/84/06/wKiom1eDb6GRCzVIAACn6l6368w671.png "border=" 0 "/>

Return to the endpoints page to see the individual site status

650) this.width=650; "height=" 214 "title=" clip_image017 "style=" Border-top:0px;border-right:0px;background-image: none;border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "Alt=" clip_image017 "src=" http://s3.51cto.com/wyfs02/M02/84/06/wKiom1eDb6HBJj-QAAAfBrU0Mhg180.png "border=" 0 "/>

Now try to parse. As you can see, the IP addresses in different regions of the world are different, reflecting the principle that traffic manager "recently" provides services

650) this.width=650; height= "title=" clip_image018 "style=" Border-top:0px;border-right:0px;background-image: none;border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "Alt=" clip_image018 "src=" http://s3.51cto.com/wyfs02/M01/84/05/wKioL1eDcNKgu_NVAAATPi9cNNQ335.png "border=" 0 "/>

650) this.width=650, "height=", "title=" clip_image019 "style=" Border-top:0px;border-right:0px;background-image: none;border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "Alt=" clip_image019 "src=" http://s3.51cto.com/wyfs02/M02/84/06/wKiom1eDcNKQJ40fAAATV_WYNI8355.png "border=" 0 "/>

Finally, create a CNAME domain name in domain management to point to the trafficmanager.net domain name

650) this.width=650; "height=" 235 "title=" clip_image020 "style=" Border-top:0px;border-right:0px;background-image: none;border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "Alt=" clip_image020 "src=" http://s3.51cto.com/wyfs02/M01/84/06/wKiom1eDcNPAicEDAABKRyapI8s815.png "border=" 0 "/>

The nslookup query found that the parsing took effect

650) this.width=650; "height=" 138 "title=" clip_image021 "style=" Border-top:0px;border-right:0px;background-image: none;border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "Alt=" clip_image021 "src=" http://s3.51cto.com/wyfs02/M00/84/06/wKiom1eDcNOQBf2dAAAV7P5Jj88199.png "border=" 0 "/>

Test Login No problem

650) this.width=650; "height=" 486 "title=" clip_image023 "style=" Border-top:0px;border-right:0px;background-image: none;border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;margin:0px;padding-right:0px; "Alt=" clip_image023 "src=" http://s3.51cto.com/wyfs02/M01/84/06/wKiom1eDcNSjZYcEAACHbxzi7kw345.jpg "border=" 0 "/>

You can even use Healthcheck to confirm that Exchange servers that provide access to different geographies
