Public Preview: Load Balancer in Azure API Management

Customers have the ability to create a load balancer that directs traffic to multiple endpoints. Customers can now create backend pools, allowing them to add multiple backends for an API and implement load balancing across those backends. This facilitates the distribution of load to multiple backends, each of which may have individual backend circuit breakers. Furthermore, customers can seamlessly shift the load from one set of backends to another, facilitating smooth upgrades.
