ELB Listener

Elastic Load Balancing (ELBv2) and AWS Certificate Manager (ACM) are two distinct AWS services that can be used together to provide secure, high-performance network traffic routing. ELBv2 is an Amazon web service that enables users to create and manage load balancers for incoming application traffic. The service automatically distributes incoming application traffic across multiple Amazon EC2 instances, thus scaling out applications across multiple availability zones for increased availability and scalability. On the other hand, ACM is a service that allows users to easily create, manage, deploy and renew SSL/TLS certificates in the cloud. An SSL/TLS certificate helps to protect websites by encrypting web communications between visitors’ browsers and websites using HTTPS protocol. By associating a certificate with an ELBv2 listener configuration, users can ensure encrypted communication between clients connecting through their load balancer and the back-end EC2 instances serving website content or applications.

The link between Amazon Web Services' (AWS) Elastic Load Balancing (ELBv2) Listener and Cognito Identity Provider (IdP) User Pool is that they work together to provide authentication services for web applications. ELBv2 Listeners are responsible for monitoring incoming requests to a load balancer and routing them to the appropriate target group, while Cognito IdP User Pools handle the authentication of users by verifying their credentials against an identity provider. This allows web applications hosted on AWS to easily authenticate users and provide a secure, reliable experience.

Elastic Load Balancing (ELBv2) is a powerful tool within the Amazon Web Services (AWS) platform that provides a secure, reliable and efficient way to route traffic between multiple EC2 instances. ELBv2-listener is an important component of the ELBv2 system, as it listens for incoming requests from external sources and then forwards them to the appropriate EC2 instance. The ELBv2-load-balancer is another important component, as it ensures that all incoming traffic is routed efficiently and securely by distributing it across multiple EC2 instances. Together, these two components provide a reliable and secure way of routing traffic across multiple EC2 instances in AWS.

The link between an ELBv2-Listener and ELBv2-TargetGroup in Amazon Web Services (AWS) is that the TargetGroup defines where traffic from your Listener should be routed. An ELBv2-Listener is a network endpoint that listens for incoming requests and routes them to the appropriate target group. A TargetGroup contains a group of target instances, such as EC2 instances, which can receive traffic from the listener. The Listener uses rules to route requests to specific target groups based on content or other criteria, allowing for advanced load balancing configurations.

The link between Amazon Web Services' (AWS) Elastic Load Balancing (ELBv2)-Listener and HTTP is that ELBv2-Listener acts as a proxy to route incoming requests from the client to the backend server. ELBv2-Listener is capable of supporting multiple protocols like HTTP(S), TCP, TLS and Websockets. By routing incoming requests through ELBv2-Listener, it ensures that the appropriate protocol is used for each request, thus allowing clients to access resources securely using HTTPS or other secure protocols. Additionally, ELBv2-Listener also provides additional features such as health checks, connection draining and sticky sessions which help ensure that clients are served content efficiently and reliably.
