Networking Load Balancing
What is Networking Load Balancing ?
NLB allows all of the computers in the cluster to be addressed by the same set of Ip addresses , and it maintains a set of unique, dedicated IP addresses for each host. For load-balanced applications, when a host fails or goes offline, the load is automatically redistributed among the computers that are still operating. When it is ready, the offline computer can transparently rejoin the cluster and regain its share of the workload, which allows the other computers in the cluster to handle less traffic

Configaration
In ADDS we create a server group
Server Group Name 🡺 web server
In the web server group we install a Role and a features 🡺 Web server(ISS) and Network Load Blanching (NLB) in both server 🡺 Web -server 1 and Web server 2
Install Role 🡺 Web server (ISS)
Features 🡺 Network Load Blanching (NLB)
After completed the Role and feature we close this window
We do the same Work on 🡺 webserver-2
Now we share this folder 🡺text (.html )
Webserver-1
In Webserver-1 🡺 I change the color Blue , because we can easily understand what server we work
Now go to Tools 🡺 Internet information service Manager (IIS)
We save the file index 🡺 location (C:\inetpub\wwwroot)
In Webserver -2
Now we going to ADDS 🡺 Tools > Network Load Balancing Manager
New cluster > connect > next
Control Host Start
In ADDS (kamrul.local) 🡺 browser > 10.0.0.10
Now we check this IP > 10.0.0.10 in DNS
DNS Manager > Forward > Lookup Zones
Webserver-1 > 10.0.0.10
Now, we start this cluster
Now we check this IP > 10.0.0.20 in DNS
DNS Manager > Forward > Lookup Zones
Webserver-2 > 10.0.0.20
In kamrul.local 🡺 DNS manager 🡺 test (uses parent domain ) And Ip 🡺 10.0.0.100
Now, we check this Which server Hit it (it Hit the server-1 Because we select the Webserver-1 color is Blue
Cluster.kamrul.local / 10.0.0.100 🡺 hit the browser 🡺 this color is “Blue” which is “webserver-1”
So, this is Process of NLB (Networking Load Balancing)
