The load balancer queues a request if it is unable to establish a connection with a healthy instance in order to route the request. Use tactical efforts to gain experience and accumulate data about cloud‑based development and deployment. At the top of the network stack, Layer 7 handles more complex traffic, such as HTTP and HTTPS requests. Like ALBs, NLBs support various types of targets in multiple availability zones.
