This could take several minutes. Connect to the Microsoft Azure portal and configure basic settings. Create a back-end pool Back-end pools specify the instances of Access Gateway being fronted by the load balancer. Click the name of the load balancer.
In the Settings section, click Backend Pools. Click the Add to add a new back-end pool. Virtual network From the drop-down box, select the virtual network containing the Access Gateway instances. Associated to Virtual machines Click Add. The new virtual machines dialog will display. Select each Access Gateway node that should be used by the load balancer.
Click Add. Click Save. Configure health probes Load balancers must be able to tell the health of the instances they interact with. In the Settings section, click Health Probes. Load balancer distributes inbound flows that arrive at the load balancer's front end to backend pool instances. These flows are according to configured load-balancing rules and health probes.
The backend pool instances can be Azure Virtual Machines or instances in a virtual machine scale set. A public load balancer can provide outbound connections for virtual machines VMs inside your virtual network.
These connections are accomplished by translating their private IP addresses to public IP addresses. Public Load Balancers are used to load balance internet traffic to your VMs. An internal or private load balancer is used where private IPs are needed at the frontend only. Internal load balancers are used to load balance traffic inside a virtual network. A load balancer frontend can be accessed from an on-premises network in a hybrid scenario. Figure: Balancing multi-tier applications by using both public and internal Load Balancer.
For more information on the individual load balancer components, see Azure Load Balancer components. Your end-to-end scenarios may benefit from combining these solutions as needed. For an Azure load-balancing options comparison, see Overview of load-balancing options in Azure. With Azure Load Balancer, you can scale your applications and create highly available services.
This demo includes the following tasks:. Step 1 Log in to Azure Portal Please make sure you have a subscription before doing all this. Also Check: Our blog post on Azure Compute. Step 2 In Create virtual network, enter or select the following information in the Basics tab:.
Check Out: What is the difference between az and az In the IP Addresses tab, enter this information:. Step 4 Under Subnet name, select the word default. Step 1 Select All services in the left-hand menu, select All resources , and then select myLoadBalancer from the resources list.
Step 2 Under Settings , select Backend pools , then select Add. Step 3 In the Add a backend pool page, enter the following information and then select Add. The load balancer monitors the status of your app with a health probe. The health probe adds or removes VMs from the load balancer based on their response to health checks. Step 2 Under Settings , select Health probes , then select Add. Step 3 Enter the below information in the Add health probe page and then select OK.
If your application consists of multiple workloads, evaluate each workload separately. A complete solution may incorporate two or more load-balancing solutions. Internet facing. Applications that are publicly accessible from the internet. As a best practice, application owners apply restrictive access policies or protect the application by setting up offerings like web application firewall and DDoS protection.
End users or clients are located beyond a small geographical area. Platform as a service PaaS services provide a managed hosting environment, where you can deploy your application without needing to manage VMs or networking resources. In this case, PaaS refers to services that provide integrated load balancing within a region.
See Choosing a compute service — Scalability. Azure Kubernetes Service enables you to deploy and manage containerized applications. Infrastructure as a service IaaS is a computing option where you provision the VMs that you need, along with associated network and storage components. IaaS applications require internal load balancing within a virtual network, using Azure Load Balancer. Application-layer processing refers to special routing within a virtual network.
For example, path-based routing within the virtual network across VMs or virtual machine scale sets. Feedback will be sent to Microsoft: By pressing the submit button, your feedback will be used to improve Microsoft products and services. Privacy policy. Skip to main content.
