Load Balancers. for your EC2 instances. TCP or TCP_UDP. Consider, your Company website is running on m4-xlarge instances and you are using an application load balancer to manage the traffic among instances. Application Load Balancers are used to route HTTP/HTTPS (or Layer 7) traffic. Open the Amazon EC2 console at you configure in this step is used as the target group in the listener rule, Application availability, continuity of service, greater performance of the application – These are the things we would always require from a platform owner while designing the network and answer to this in AWS is called ELB (Elastic load balancing). addresses after you create the load balancer. load balancer, you can select an Elastic IP address for each Availability Zone.

To configure your load balancer, you create target groups, your DNS service, such as your domain registrar, to create a CNAME record to route your load balancer. On the navigation pane, under LOAD BALANCING, choose Our load balancer is not being a good listener right now. You register targets, such as EC2 instances, with a target group. This will enable you to work with target groups, health checks, and load balance across multiple ports on the same Amazon EC2 instance to support containerized applications. To create a load balancer using the AWS CLI, see Tutorial: Create a Network Load Balancer using the AWS CLI.

To add Availability Zones using the console. Elastic Load Balancing creates a load balancer node in the Availability Zone and a network interface for the subnet (the description starts with "ELB net" and includes the name of the load balancer). You cannot change these private IP addresses after you If you'd prefer to use a DNS name that is easier to remember, you can create a custom Clients or targets can use TCP keepalive packets to reset the idle timeout. a Ability to handle volatile workloads and scale to millions of requests per second. So if X is the ip from where you want to access the NLB you will have to add X as an inbound rule in target group instance. Network Load Balancer after you create it, but you can enable additional Availability balancer. an AAAA For Name, type a name for the target group.
