Azure Load Balancer is a highly available and scalable load balancing service provided by Microsoft Azure to distribute incoming internet traffic across multiple virtual machines or cloud services. With the use of Azure Load Balancer, we can efficiently handle high traffic loads and prevent downtime for our cloud application. In this tutorial, we will implement Azure Load Balancer for web traffic to ensure high availability, scalability, and the distribution of traffic across multiple virtual machines.<\/p>\n
Before implementing Azure Load Balancer, we need to ensure the following prerequisites:<\/p>\n
If you haven’t already done so, please ensure that you have satisfied the above prerequisites.<\/p>\n
Azure Load Balancer is a Layer 4 (TCP\/UDP) load balancer that provides high availability by evenly distributing incoming traffic over multiple virtual machines. It works by analyzing the incoming traffic and choosing the appropriate virtual machine to handle the request based on the configured rule sets.<\/p>\n
Azure Load Balancer supports two modes of distribution:<\/p>\n
Azure Load Balancer also provides support for various protocols, including TCP, UDP, and HTTP\/HTTPS. This makes it possible to use it for different types of applications, such as web servers, database servers, and custom applications.<\/p>\n
In this step-by-step guide, we will implement Azure Load Balancer for web traffic. We will assume that you have created at least two VMs with web servers installed, and they are assigned static public IP addresses.<\/p>\n
If you don’t have any VMs set up in Azure, you can follow Microsoft Azure’s documentation to create them.<\/p>\n
Open the Azure portal and navigate to the “Load Balancers” option in the left-hand menu. Then click on the “Add” button.<\/p>\n
<\/p>\n
Configure the following settings:<\/p>\n
<\/p>\n
Once the configuration is complete, click on the “Review + create” button to proceed. Then, click “Create” to deploy your load balancer.<\/p>\n
Now we need to create a backend pool for the load balancer to distribute traffic to. This backend pool will contain the IP addresses of the VMs that will serve as web servers.<\/p>\n
Click on the “Backend pools” option in the “Settings” menu of your load balancer. Then click on the “Add” button to create a new backend pool.<\/p>\n
<\/p>\n
Configure the following settings:<\/p>\n
<\/p>\n
Once the configuration is complete, click the “Add” button to create the backend pool.<\/p>\n
To ensure that the backend pool only contains healthy VMs, we need to create a health probe. This health probe will actively monitor the health of the VMs and remove any unhealthy VMs from the backend pool.<\/p>\n
Click on the “Health probes” option in the “Settings” menu of your load balancer. Then click on the “Add” button to create a new health probe.<\/p>\n
<\/p>\n
Configure the following settings:<\/p>\n
<\/p>\n
Once the configuration is complete, click the “Add” button to create the health probe.<\/p>\n
Now that our backend pool and health probe are created, we need to create a load balancing rule. This rule will define how traffic will be distributed to the backend pool.<\/p>\n
Click on the “Load balancing rules” option in the “Settings” menu of your load balancer. Then click on the “Add” button to create a new load balancing rule.<\/p>\n
<\/p>\n
Configure the following settings:<\/p>\n
<\/p>\n
Once the configuration is complete, click the “Add” button to create the load balancing rule.<\/p>\n
To allow traffic to flow through the load balancer to the backend pool, we need to configure the network security group associated with the backend VMs.<\/p>\n
Click on the “Network security group” option in the left-hand menu. Then click on the network security group associated with the backend VMs.<\/p>\n
<\/p>\n
Then click on the “Inbound security rules” option in the “Settings” menu. Click on the “Add” button to create a new inbound security rule.<\/p>\n
<\/p>\n
Configure the following settings:<\/p>\n
<\/p>\n
Once the configuration is complete, click the “Add” button to create the inbound security rule.<\/p>\n
After completing the above steps, your Azure Load Balancer should be ready to distribute traffic evenly across the backend VMs. You can test the load balancer by navigating to the public IP address associated with your load balancer.<\/p>\n
In this tutorial, we have implemented Azure Load Balancer for web traffic. We created a load balancer, a backend pool, a health probe, a load balancing rule, and configured the network security group to allow traffic to flow through to the backend pool. With these steps complete, we have successfully created a highly available, scalable, and reliable load balancing solution for our cloud application.<\/p>\n","protected":false},"excerpt":{"rendered":"
