Introduction to Azure Load Balancer. Microsoft Azure offers a load balancing service that allows loads of inbound network traffic to be distributed across different.

Introduction to Azure Load Balancer :

Microsoft Azure offers a load balancing service to distribute loads of inbound network traffic across different machines or virtual servers in the backend. A load balancer helps maintain a high availability and makes hardware and software resilient to failure. Azure acts as a transport layer in the Open System Interconnection (OSI) model. The load balancer does not indicate the traffic on the failed machine.

Azure Load Balancer uses two types of configuration modes:

  • External – Public load balancing
  • Internal – Internal load balancing

Working of Azure Load Balancer :

Microsoft Azure offers load balancing in two modes on the network so that inbound traffic flows are based on the configured rules of load balancing. Load Balancer helps us scale applications and create highly available services. Here are two modes of Azure Load Balancer:

1. Public (External) load balancer

A public Load balancer gives the outbound association with the virtual machines (VMs) from the pool of backend virtual organizations. For these outbound associations, all the private IP addresses are changed over to the Public IP addresses so that each heap balancer gets doled out with one Public IP address to acknowledge the solicitation coming from the web. Whenever load balancer gets called from the client applications then, at that point, in light of the heap balancer arrangement inbound traffic is dispersed among Virtual Machines.

2. Private (Internal) load balancer

Private burden balancers are utilized assuming we want private IPs at the frontend. This heap balancer utilizes a private IP address to call and all traffic is steered to within the virtual organization to the mentioned virtual machines. The inner burden balancer utilizes source IP, source port, objective IP, objective port, and the convention type to adjust the web traffic in virtual machines. It utilizes a hash capacity to circulate this heap. In the Ifurce to objective IP association is lost, the hash work frames another association with discrete endpoints.

How to Create an Azure Load Balancer :

1. Log in to Azure Portal using a valid username and password:

2. Select Create a resource from the portal's home page.

Features of Azure Load Balancer :

Below are mentioned the features:

  1. Load Balancer: Azure Load Balancer provides an option to configure the load balancer based on users' roles. Internet traffic is balanced on Azure virtual machines based on internal or external load balancer mode.
  2. Availability Set: Load Balancer distributes aerial resources between and across virtual machines and regions.
  3. Port Forwarding: Provides the ability to forward traffic ports to a specific virtual server using public IP addresses and ports.
  4. Application agnostic and transparent: This feature allows the user to manage traffic based on URL or multi-site hosting because the load balancer does not interact directly with TCP / IP or UDP but also with TCP and UDP streams across all ports simultaneously with HA. (High availability) port.
  5. Automatic rearrangement: Load balancer features If we scale machines up or down in the backend pool, it has the feature of reconfiguring itself.
  6. Health Search: Load Balancer has a feature that stops the flow of traffic on failed machines which in turn helps to identify failed virtual machines and this is done using a health search. Users can configure a health probe to check the health status of the server in the backend
  7. Outbound connections: Load Balancer provides outbound connections to public or private IP addresses of Azure virtual machines within the virtual network.

Conclusion :

Microsoft Azure offers the information load balance administration to keep up with the high accessibility and versatility of the virtual machines and offers programmed reconfiguration of the framework so clients have less exertion in the upkeep of the Azure with these administrations. Anything that clients do on the web we want to adjust the heap and it is finished utilizing these administrations. Here we have likewise figured out how to make an Azure burden balance and arrange similar in the view given.
