Microsoft Azure Cloud Enterprise Exchange 2016 deployment 12-Configure load Balancing

We have configured the Exchange2016 mailbox system in the last few sections, this section we configure the ports that need to be opened, and load-balance the ports, as shown in the red box:

1.Exchange Service Port

Exchange2016 need to open the following ports to provide different services to the external:

One of the most important things about HTTPS (443) ports, the following services need to use this port:

Auto Discovery Service

Exchange ActiveSync

Exchange Web Service (EWS)

Offline Address Book

Outlook everywhere

MAPI over HTTP in Exchange 2016

So port 443 must be open to inbound ports, and the rest of the ports, such as 80, 110, 143, 993, 995, 587, and so on, will also need to open inbound ports when using the appropriate service.

In addition, SMTP port 25 is required for mail entry and exit, so you also need to open the inbound 25 port.

2. Azure Load balancer (SLB)

Azure virtual machines communicate externally with an endpoint, and these endpoints can be configured with a load-balanced set that joins Azure. Azure's load-balanced set is a 4-tier (TCP, UDP) load balancing that can distribute traffic across multiple virtual machines. Azure SLB is a 4th-tier (TCP, UDP) software load balancer that calculates the hash function of the available server for mapping traffic to the VIP using a 5-tuple (source IP, source port, destination IP, destination port, protocol type). The hash function allows the distribution of connections to the server to be randomized rather than perfectly polled. In addition, session affinity is not currently supported

Let's add a load-balanced set based on azure endpoints.

We choose Azure Virtual Machine EX01, go to the Endpoint Configuration page, click Add

650) this.width=650; "height=" 340 "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/M01/83/F2/wKiom1eAzsLRK9xCAAAtinQwFKA284.png "border=" 0 "/>

First, add a standalone endpoint.

650) this.width=650; "height=" "title=" clip_image010 "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_image010 "src=" http://s3.51cto.com/wyfs02/M00/83/F1/wKioL1eAzsOClLrCAAApOXhZ0z4370.png "border=" 0 "/>

This configures the HTTPS 443 port and simultaneously chooses to create a load-balanced set

650) this.width=650; "height=" 433 "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/M01/83/F1/wKioL1eAzsay6sQpAAAqjRDLjMI237.png "border=" 0 "/>

Define parameters such as name, probe interval, and so on

650) this.width=650; "height=" 485 "title=" clip_image012 "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_image012 "src=" http://s3.51cto.com/wyfs02/M01/83/F2/wKiom1eAzsfDtTgyAAAr1h9ZK9I834.png "border=" 0 "/>

EX01 Configuration Complete

650) this.width=650; "height=" 175 "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/M00/83/F1/wKioL1eAzsfjGGQaAABBmJ6BpKo594.jpg "border=" 0 "/>

Now choose EX02, this time select Add to existing load balanced set

650) this.width=650; "height=" "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/M02/83/F2/wKiom1eAzsfQcoCMAAApQ4qxr7Y044.png "border=" 0 "/>

Save after confirmation

650) this.width=650; "height=" 491 "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/M00/83/F1/wKioL1eAzsiDZSP7AAAygMVsrrE172.png "border=" 0 "/>

In this way, the EX02 endpoint is also configured.

650) this.width=650; "height=" 178 "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/M01/83/F2/wKiom1eAzsjS_juCAABQRkMsx7I023.jpg "border=" 0 "/>

Similarly, if we need exchange other services such as POP, IMAP and so on, we can make the same configuration for the corresponding port, and we will not repeat it here.

Now let's do some simple tests.

First of all, since we don't have a fixed public address, we now see the public IP assigned to the ex cloud service by Azure as 13.78.59.202

650) this.width=650; "height=" 281 "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/M01/83/F1/wKioL1eAzsjSWZE5AAAb2VO_dmk434.png "border=" 0 "/>

Now let's telnet the SMTP port to verify the configuration of the load balancer so that the server that can differentiate the port response

650) this.width=650; "height=" "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/M02/83/F2/wKiom1eAzsniR9raAAAmTjAB-uo686.png "border=" 0 "/>

Telnet address, found EX01 responded.

650) this.width=650; "height=" 106 "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/M02/83/F1/wKioL1eAzsnCAvjTAAAaJcgDc8k191.png "border=" 0 "/>

Telnet again and discover this is EX02 to respond to the connection

650) this.width=650; "height=" "title=" clip_image022 "style=" Border-top:0px;border-right:0px;background-image: none;border-bottom:0px;padding-top:0px;padding-left:0px;border-left:0px;padding-right:0px; "alt=" clip_image022 " Src= "Http://s3.51cto.com/wyfs02/M00/83/F1/wKioL1eAzsnyrugDAAAZZg3pC-s293.png" border= "0"/>

Similarly, other ports can be tested, although the response of other ports may not be so friendly, but the port can be connected, or can be tested.
