Azure Load Balancer Pricing & Demo

Azure Load Balancer is a load balancing software that operates at layer four of the Open Systems Interconnection (OSI) model. It acts as a single point of contact for the clients by distributing inbound flows arriving at the load balancer’s front end to back end pool instances. The configuration of these flows is according to the load balancing rules and health probes. Azure Virtual Machines or instances in a virtual machine scale set can be the backend pool instances. Suitable for both single-tier and multi-tier instances and also for tailor-made instances.
