What is the purpose of target groups in AWS?
A target group tells a load balancer where to direct traffic to : EC2 instances, fixed IP addresses; or AWS Lambda functions, amongst others. When creating a load balancer, you create one or more listeners and configure listener rules to direct the traffic to one target group.
What is a target group?
Target groups are individuals or groups (families, teams, organizations) that generally live in a geographically circumscribed area (thus, in cities, individual municipal or rural districts). For the needs assessment, it’s important to describe the target group as precisely as possible.
What is difference between ALB and NLB?
Key Differences NLB just forward requests whereas ALB examines the contents of the HTTP request header to determine where to route the request. Generally a NLB determines availability based on the ability of a server to respond to ICMP ping, or to correctly complete the three-way TCP handshake.
How do I set up a target group?
Create a target group
- On the navigation pane, under LOAD BALANCING, choose Target Groups.
- Choose Create target group.
- For Choose a target type, select Instances to register targets by instance ID, IP addresses to register targets by IP address, or Lambda function to register a Lambda function as a target.
What is target group port?
The port the load balancer uses when performing health checks on targets. If the protocol is HTTP, HTTPS, TCP, TLS, UDP, or TCP_UDP, the default is traffic-port , which is the port on which each target receives traffic from the load balancer.
Can a load balancer have multiple target groups?
This is exactly what an Application Load Balancer is designed to do. You can create multiple Target Groups. Each target group has: A name.
What are the four targeting strategies?

Which is better NLB or ALB?
Network Load Balancer Its main feature is that it has a very high performance. NLB natively preserves the source IP address in TCP/UDP packets; in contrast, ALB and ELB can be configured to add additional HTTP headers with forwarding information, and those have to be parsed properly by your application.
What does ELB stand for?
Elastic Load Balancing (ELB) is a load-balancing service for Amazon Web Services (AWS) deployments. ELB automatically distributes incoming application traffic and scales resources to meet traffic demands. ELB helps an IT team adjust capacity according to incoming application and network traffic.
How do target group and Auto Scaling group work together?
When you attach an Application Load Balancer, Network Load Balancer, or Gateway Load Balancer, you attach a target group. Amazon EC2 Auto Scaling adds instances to the attached target group when they are launched. You can attach one or multiple target groups, and configure health checks on a per target group basis.
How do I add a load balancer to a target group?
Create a target group for your Network Load Balancer
- In the navigation pane, under Load Balancing, choose Target Groups.
- Choose Create target group.
- For Choose a target type, select Instances to register targets by instance ID or IP addresses to register targets by IP address.
