What is AWS ELB?
Elastic Load Balancing distributes incoming traffic automatically across multiple targets such as Amazon EC2 instances and containers, IP addresses and Lambda function. It can manage the different load of your application traffic within a single or multiple Availability zones.
How does AWS ELB function in this regard?
How elastic load balance works. A load balancing takes in traffic from clients and routes it to its registered targets (such EC2 instances), in one or more Availability zones. The load balancer monitors the health and routes traffic to only healthy targets.
What is an ELB, and what are its benefits? An ELB, a software-based loadbalancer, can be configured and set up in front of a group of AWS Elastic Compute instances (EC2). The load balancer acts as a single point of entry for users of the EC2 instances. It distributes incoming traffic across all available machines.
This being said, how do you use ELB in AWS?
Elastic Load Balancing is a load-balancing solution for Amazon Web Services (AWS). ELB distributes all incoming traffic automatically and scales resources to meet traffic demand.
What are the different types of ELB in AWS?

What is the difference between application and classic load balancer?
The Classic Load Balancer operates on both the request and connection levels. A Classic Load Balancer is recommended only for EC2 Classic instances. The Application Load Balancer operates at the request level only. If you're dealing with HTTP requests, which you are for your web application, you can use this.
What is difference between ALB and ELB?
Application Load Balancer enables content-based routing and allows requests to be routed to different applications behind a single load balance. While the Classic Load Balancer doesn't do that, a single ELB can host single application. ALB isn't an improved Classic Load balancer. It's made on a completely new platform.
Does ELB change IP?
3 Answers. ELB's IP address keeps changing. You should instead use the DNS name provided to you. The short answer: Yes, ELB's IP addresses (both the ones that are publicly distributed to clients of your service, and the internal IPs from which ELB sends traffic to your instances) dynamically change.
Do load balancers have IP addresses?
However, Classic Load Balancers and Application Load Balancers use the private IP addresses associated with their elastic network interfaces as the source IP address for requests forwarded to your web servers.
What happens if ELB goes down?
If one load balancer fails, the secondary picks up the failure and becomes active. They have a heartbeat link between them that monitors status. 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.
Does ELB have IP address?
Each load balancer instance has its own IP address registered in the DNS service on Amazon's side. This is also why Amazon only provides a DNS for the ELB, because a static IP address does not exist that can be used instead.
How much does an ELB cost?
Classic Load Balancer in US-East-1 will cost $0.025 per hour (or partial hour), plus $0.008 per GB of data processed by the ELB. Use the AWS Simple Monthly Calculator to help you determine the load balancer pricing for your application. Just look under the EC2 tab on the left side of the page.
What is application load balancing?

What is HTTP load balancing?
