How to create Azure Loadbalancer

What is Azure Load Balancer? Azure Load Balancer is a cloud service that distributes incoming network traffic across backend virtual machines (VMs) or virtual machine scale sets (VMSS). This article explains Azure Load Balancer's key features, architecture, and scenarios, helping you decide if it fits your organization's load balancing needs for scalable, highly available workloads. Load balancing refers to efficiently distributing incoming network traffic across a group of backend virtual machines (VMs) or virtual machine scale sets (VMSs Azure Load Balancer is one of the services that Load balancer overview Azure Load Balancer operates at layer 4 of the Open Systems Interconnection (OSI) model. It's the single point of contact for clients. The service distributes inbound flows that arrive at the load balancer's frontend to backend pool instances. These flows are distributed according to configured load-balancing rules and health probes. The backend pool instances can be Azure virtual machines (VMs) or virtual machine scale sets. A public load balancer can provide both inbound and outbound connectivity for the VMs inside your virtual network. For inbound traffic scenarios, Azure Load Balancer can load balance internet traffic to your VMs. For outbound traffic scenarios, the service can translate the VMs' pri. With internal load balancer, you can provide inbound connectivity to your VMs in private network connectivity scenarios, such as accessing a load balancer frontend from an on-premises network in a hybrid scenario.Why use Azure Load Balancer With Azure Load Balancer, you can scale your applications and create highly available services. The service supports both inbound and outbound scenarios, provides low latency and high throughput, and scales up to millions of flows for all TCP and UDP applications. Core capabilities Azure Load Balancer provides: High availability: Distribute resources within and across availability zones Scalability: Handle millions of flows for TCP and UDP applications Low latency: Use pass-through load balancing for ultralow latency Flexibility: Support for multiple ports, multiple IP addresses, or both Health monitoring: Use health probes to ensure traffic is only sent to healthy instances Traffic distribution scenarios Load balance internal and external traffic to Azure virtual machines Configure outbound connectivity for Azure virtual machines Load balance TCP and UDP flow on all ports simultaneously using high-availability ports Enable port forwarding to access virtual machines by public IP address and port Advanced features IPv6 support: Enable load balancing of IPv6 traffic Cross-region mobility: Move internal and external load balancer resources across Azure regions Gateway load balancer integration: Chain Standard Load Balancer and Gateway Load Balancer Global load balancing integration: Distribute traffic across multiple Azure regions for global applications Admin State: Override health probe behavior for maintenance and operational management Monitoring and insights Comprehensive Health Event Logs: Monitor load balancer health events and status changes for proactive management Load Balancer health status: Gain deeper insights into the health of your load balancer through health status monitoring Security features Azure Load Balancer implements security through multiple layers: Zero Trust security model Standard Load Balancer is built on the Zero Trust network security model Part of your virtual network, which is private and isolated by default Network access controls Standard load balancers and public IP addresses are closed to inbound connections by default Network Security Groups (NSGs) must explicitly permit allowed traffic Traffic is blocked if no NSG exists on a subnet or NIC Data protection Azure Load Balancer doesn't store customer data All traffic processing happens in real-time without data persistenceAzure Load Balancer serves as the single point of contact for clients at layer 4 of the Open Systems Interconnection (OSI) model. It distributes inbound traffic that arrives at the front end to pool instances on the backend.Azure? Azure load-balancing services You can choose from three different load-balancing methods: round-robin, weighted, and priority based. Application Gateway provides application delivery controller as a service, offering various Layer 7 load-balancing capabilities and web application firewall functionality. The Basic Azure Load Balancer is free of charge, but is not provided along with the basic Virtual Machine. No additional charges for packets routed from Global-tier (Cross-region) Load Balancer to Regional-tier Load Balancer.In Azure, a Network Security Group (NSG) acts as a virtual firewall that filters network traffic to and from Azure resources within a virtual network. It controls inbound and outbound traffic based on rules that specify source/destination, ports, and protocols. NSGs can be associated with subnets or network.
