How do I check traffic on my load balancer?

You can use these access logs to analyze traffic patterns and to troubleshoot issues with your targets. For more information, see Access logs for your Application Load Balancer. You can use request tracing to track HTTP requests. The load balancer adds a header with a trace identifier to each request it receives.

What is l7 load balancing?

Layer 7 load balancing allows the load balancer to route a request based on information in the request itself, such as what kind of content is being requested. So now a request for an image or video can be routed to the servers that store it and are highly optimized to serve up multimedia content.

What are the types of load balancers?

Elastic Load Balancing supports the following types of load balancers: Application Load Balancers, Network Load Balancers, and Classic Load Balancers. Amazon ECS services can use either type of load balancer. Application Load Balancers are used to route HTTP/HTTPS (or Layer 7) traffic.

If all load balancers fail (or are accidentally misconfigured), servers down-stream are knocked offline until the problem is resolved, or you manually route around them.

Why is load balancing important?

The main purpose of load balancing is to prevent any single server from getting overloaded and possibly breaking down. In other words, load balancing improves service availability and helps prevent downtimes.
